Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	General The accompanying unaudited Condensed Consolidated Financial Statements of Weatherford International plc (the “Company,” “Weatherford” or “Weatherford Ireland”) are prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and include all adjustments, consisting of normal recurring adjustments, which in our opinion, are considered necessary to present fairly our Condensed Consolidated Balance Sheets at June 30, 2019 and December 31, 2018, Condensed Consolidated Statements of Operations and Condensed Consolidated Statements of Comprehensive Loss for the three and six months ended June 30, 2019 and 2018 and Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2019 and 2018. When using phrases such as “we,” “us,” and “our,” the intent is to refer to Weatherford International plc, a public limited company organized under the law of Ireland, and its subsidiaries as a whole or on a regional basis, depending on the context in which the statements are made. Although we believe the disclosures in these financial statements are adequate, certain information relating to our organization and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted in this Form 10-Q pursuant to U.S. Securities and Exchange Commission (“SEC”) rules and regulations. These financial statements should be read in conjunction with the audited Consolidated Financial Statements for the year ended December 31, 2018 included in our Annual Report on Form 10-K. The results of operations for the three and six months ended June 30, 2019 are not necessarily indicative of the results expected for the year ending December 31, 2019 for which we expect to file the related Annual Report on Form 10-K as an accelerated filer, our first period affected by the change in filing status based on our public float as of the last business day of our second fiscal quarter of 2019. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements, the reported amounts of revenues and expenses during the reporting period, and disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our estimates and assumptions, including those related to uncollectible accounts receivable, lower of cost or net realizable value of inventories, assets and liabilities held for sale, derivative financial instruments, intangible assets and goodwill, property, plant and equipment (“PP&E”), right-of-use (“ROU”) lease assets, income taxes, accounting for long-term contracts, self-insurance, foreign currency exchange rates, lease liabilities, pension and post-retirement benefit plans, disputes, litigation, contingencies and share-based compensation. We base our estimates on historical experience, adjusted for current conditions if necessary, and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates. Principles of Consolidation We consolidate all wholly owned subsidiaries and controlled joint ventures. All material intercompany accounts and transactions have been eliminated in consolidation. Reclassifications Certain reclassifications of the financial statements and accompanying footnotes for the three and six months ended June 30, 2018 have been made to conform to the presentation for the three and six months ended June 30, 2019. See “Note 3 – New Accounting Pronouncements” for additional details regarding accounting changes impacting the Condensed Consolidated Financial Statements.

Chapter 11 Proceedings and Abilitiy to Continue as a Going Concern

Reorganizations [Abstract]

Chapter 11 Proceedings and Ability to Continue as a Going Concern

Voluntary Reorganization Under Chapter 11 of the U.S. Bankruptcy Code

On July 1, 2019, Weatherford Ireland, Weatherford International Ltd. (“Weatherford Bermuda”), and Weatherford International, LLC (“Weatherford Delaware”) (collectively, “Weatherford Parties,” or “Debtors”), filed voluntary petitions under Chapter 11 of the U.S. Bankruptcy Code (“Bankruptcy Code”) in the U.S. Bankruptcy Court for the Southern District of Texas (“Bankruptcy Court”). The Debtors have obtained joint administration of their Chapter 11 cases under the caption In re Weatherford International plc, et al., Case No. 19-33694 (“Cases”). On June 28, 2019, the Debtors commenced a solicitation for acceptance of their prepackaged plan of reorganization (“Plan”) by causing the Plan and the corresponding disclosure statement to be distributed to certain creditors of the Company.

Weatherford Ireland anticipates filing a petition under the Irish Companies Act 2014 in Ireland (“Irish Examinership Proceeding”) following confirmation of the Plan by the Bankruptcy Court to seek approval for its scheme of arrangement. The filing of the Irish Examinership Proceeding will commence a 100 calendar day protection period under Irish law, during which Weatherford Ireland will have the benefit of protection against enforcement and other actions by its creditors. Weatherford Ireland intends to continue operating its business in the ordinary course during the protection period.

Weatherford Bermuda has commenced provisional liquidation proceedings (“Bermuda Proceedings”) pursuant to the Bermuda Companies Act 1981 by presenting a winding up petition to the Supreme Court of Bermuda (“Bermuda Court”). The Bermuda Court appointed a provisional liquidator who acts as an officer of the Bermuda Court, and is required under the Bermuda Court’s order to report from time to time on the progress of the Bermuda Proceedings. The provisional liquidator will have the power to oversee Weatherford Bermuda’s restructuring process. The Debtors’ management team and board of directors will remain in control of Weatherford Bermuda’s day-to-day operations and its Cases. The appointment of the provisional liquidator provided an automatic statutory stay of proceedings in Bermuda against Weatherford Bermuda and its assets. On the return date of September 6, 2019 for the Bermuda petition – similar to a second day hearing in a Chapter 11 proceeding – Weatherford Bermuda will seek to postpone its petition for a specified period, while the U.S. Bankruptcy Court and the Irish Examiner administer its Cases. Before the Debtors emerge from Chapter 11, Weatherford Bermuda may, along with the provisional liquidator and subject to the direction of the Bermuda Court, convene meetings of the impaired creditors in order to consider and approve, if appropriate, a scheme of arrangement pursuant to the Bermuda Companies Act 1981. It is anticipated that a the terms of the scheme will mirror the terms of the Plan and once properly approved, is a mechanism for ensuring that all of the impaired creditors of Weatherford Bermuda are bound by the terms of the Plan.

Our remaining non-debtor affiliates that have not filed voluntary petitions under the Plan will continue operating their businesses and facilities without disruption to customers, vendors, partners or employees. The Plan and requested first day relief provide that vendors and other unsecured creditors who continue to work with the non-debtor affiliates on existing terms will be paid in full and in the ordinary course of business (in the case of creditors of the Debtors, following consummation of the Plan). All existing customer and vendor contracts are expected to remain in place and be serviced in the ordinary course of business.

Subject to certain exceptions, under the Bankruptcy Code, the filing of the Cases automatically enjoined, or stayed, the continuation of most judicial or administrative proceedings or filing of other actions against the Debtors or their property to recover, collect or secure a claim arising prior to the date of the Cases. All of the Debtors’ prepetition unsecured senior notes are subject to compromise and treatment under the Bankruptcy Code. Since the commencement of the Cases, the Debtors have continued to operate their businesses as debtors-in-possession under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court.

Restructuring Support Agreement

On May 10, 2019, the Debtors entered into the Restructuring Support Agreement (“RSA”) with certain holders of our unsecured notes (“Consenting Creditors”). The RSA sets forth, subject to certain conditions, the terms of the capital financial restructuring of the Company (“Transaction”) and, as of July 12, 2019, includes the commitment of Consenting Creditors holding over 80% in aggregate principal amount of our outstanding unsecured notes.

The Transaction will be approved through the confirmation of the Plan filed in the Cases.

The RSA contemplates a comprehensive deleveraging of our balance sheet and a reduction of approximately $5.85 billion of our funded debt and provides, in pertinent part, as follows (as further described in later paragraphs):

•

Our existing unsecured notes will be cancelled and exchanged for 99% of the ordinary shares of the reorganized Company (“New Common Stock”) and $1.25 billion of new tranche B senior unsecured notes to be issued by the reorganized Company with a seven-year maturity. Holders shall have the option to convert up to $500 million of the tranche B unsecured notes to New Common Stock at the mid-point of plan equity value. The tranche B unsecured notes will be pari passu with the tranche A senior unsecured notes.


•	Our existing secured funded debt and unsecured revolving credit facility debt will be repaid in full in cash in connection with the Transaction. The secured funded debt was repaid in full on July 3, 2019.


•	All trade claims against the Company whether arising prior to or after the commencement of the Cases will be paid in full in the ordinary course of business.


•	Our existing equity will be cancelled and exchanged for 1% of the New Common Stock and three-year warrants to purchase 10% of the New Common Stock.

•

Our DIP Credit Agreement will be repaid or refinanced in full upon completion of the Transaction through the Company’s entry into a first lien exit revolving credit facility in the principal amount of up to $1.0 billion and issuance of up to $1.25 billion of new tranche A senior unsecured notes with a five-year maturity (the “Tranche A Notes”), which will be fully backstopped by the Consenting Creditors. On July 1, 2019, the Weatherford Parties entered into the backstop commitment agreement and on July 3, 2019, the Weatherford Parties entered into the DIP Credit Agreement.

The RSA includes certain milestones for the progress of the Cases, which include the dates by which the Weatherford Parties are required to, among other things, obtain certain court orders and complete the Transaction. In addition, the parties to the RSA will have the right to terminate the RSA and their support for the Transaction under certain circumstances, including, in the case of the Weatherford Parties, if the board of directors of any Weatherford Party determines in good faith that performance under the RSA would be inconsistent with its fiduciary duties. Accordingly, no assurance can be given that the Transaction described in the RSA will be completed.

Payments Due on Certain Indebtedness

The Debtors’ 7.75% Senior Notes due 2021, 8.25% Senior Notes due 2023 and 6.80% Senior Notes due 2037 (together, “Certain Senior Notes”) provide for an aggregate $69 million interest payment that became due on June 15, 2019. The applicable indenture governing the Certain Senior Notes provides a 30-day grace period that extended the latest date for making this interest payment to July 16, 2019, before an event of default would occur under the applicable indenture. The Debtors elected to not make this interest payment on the due date and to utilize the 30-day grace period provided by the indentures. As of June 30, 2019, there was no event of default. As a result of filing the Cases on July 1, 2019, an event of default occurred under each indenture governing these unsecured notes, which automatically accelerated maturity of the principal, plus any accrued and unpaid interest, on such series of unsecured notes and certain other obligations of the Debtors. Any efforts to enforce such payment obligations under the unsecured notes or other accelerated obligations of the Debtors are automatically stayed as a result of the Cases, and the creditors’ rights of enforcement in respect of the unsecured notes and other accelerated obligations of the Debtors are subject to the applicable provisions of the Bankruptcy Code. The interest and principal on this indebtedness remains unpaid as of this report date.

The Debtors’ Term Loan Agreement required a quarterly payment of $12.5 million plus interest that became due on June 30, 2019 and was unpaid as of June 30, 2019. On July 1, 2019, the Debtors and the Term Loan Lenders entered into a Term Loan Forbearance Agreement where the lenders agreed to forbear from exercising their rights and remedies available to them, including the right to accelerate any indebtedness, for a specified period of time. As of July 3, 2019, all unpaid principal and interest under the Term Loan Agreement were repaid in full. See discussion below.

Forbearance Agreements

On July 1, 2019, the Debtors and the Credit Agreement Lenders under the Amended and Restated Credit Agreement (the “A&R Credit Agreement”), dated as of May 9, 2016, among WOFS Assurance Limited and Weatherford Bermuda, as borrowers, the Company, JPMorgan Chase Bank, N.A., as administrative agent, and the lenders from time to time party thereto entered into a forbearance agreement (the “Credit Agreement Forbearance Agreement”) with respect to certain defaults under the A&R Credit Agreement, including those arising from the Debtors’ commencement of the Cases. Specifically, under the Credit Agreement Forbearance Agreement, the Credit Agreement Lenders agreed to forbear from exercising their rights and remedies available to them due to the Specified Defaults defined in the agreement, including the right to accelerate any indebtedness, for a specified period of time. Under the terms of the Credit Agreement Forbearance Agreement, the Debtors paid a fee for the ratable account of the Credit Agreement Lenders in an amount equal to 0.25% on the outstanding principal amount of the loans and total letter of credit exposure under the A&R Credit Agreement. Additionally, (i) to the extent such entities were not already guarantors under the Credit Agreement, all subsidiaries of the Company who are guarantors under the DIP Credit Agreement (defined below) joined as guarantors under the Credit Agreement and (ii) all U.S. and Canadian subsidiaries of the Company granted a second lien security interest in favor of the Credit Agreement Lenders in the same assets that such U.S. and Canadian subsidiaries pledged a first lien security interest in under the DIP Credit Agreement; provided that the aggregate amount of the guaranteed obligations to be secured under the Credit Agreement did not exceed $100 million; and provided, further, that if the obligations under the A&R Credit Agreement are not paid in full by November 30, 2019, such second lien security interest of the Credit Agreement Lenders shall automatically transition from second liens to pari passu liens with the liens under the DIP Credit Agreement.

On July 1, 2019, the Debtors and the Term Loan Lenders under the Term Loan Agreement, dated as of May 4, 2016, among Weatherford Bermuda, as borrower, the Company, JPMorgan Chase Bank, N.A., as administrative agent, and the lenders from time to time party thereto (the “Term Loan Agreement”) entered into a forbearance agreement (the “Term Loan Forbearance Agreement”) with respect to certain defaults under the Term Loan Agreement. Specifically, under the Term Loan Forbearance Agreement, the Term Loan Lenders agreed to forbear from exercising their rights and remedies available to them due to the Specified Defaults defined in the agreement, including the right to accelerate any indebtedness, for a specified period of time. On July 3, 2019, the Company repaid its outstanding indebtedness under the Term Loan.

On July 1, 2019, the Debtors and the 364-Day Lenders under the 364-Day Revolving Credit Agreement, dated August 16, 2018, among Weatherford Bermuda, as borrower, the other borrowers party thereto, the Company, JPMorgan Chase Bank, N.A., as administrative agent, and the lenders from time to time party thereto (“364-Day Credit Agreement”) entered into a forbearance agreement (the “364-Day Revolving Forbearance Agreement”) with respect to certain defaults under the 364-Day Credit Agreement. Specifically, under the 364-Day Revolving Forbearance Agreement, the 364-Day Lenders agreed to forbear from exercising their rights and remedies available to them due to the Specified Defaults defined in the agreement, including the right to accelerate any indebtedness, for a specified period of time. On July 3, 2019, the Company repaid its outstanding indebtedness under the 364-Day Revolving Credit Agreement.

On July 1, 2019, the Debtors and three lenders under the DIP Credit Agreement (the “Swap Counterparties”) each party to a hedging agreement with Weatherford Bermuda for the purpose of hedging foreign currency exposure incurred by the Weatherford Parties (each, a “Swap Agreement” and, collectively, the “Swap Agreements”) entered into a consent to swap agreement termination forbearance (the “Swap Forbearance Agreement”) with respect to certain defaults under the Swap Agreements. Specifically, under the Swap Forbearance Agreement, the Swap Counterparties agreed to forbear from exercising their rights and remedies available to them due to certain Events of Default and Termination Events defined in the agreements for a specified period of time. On July 3, 2019, the Weatherford Parties entered into amended and restated Swap Agreements with such Swap Counterparties to govern existing and future foreign currency transactions entered into with such Swap Counterparties.

Backstop Commitment Agreement

On July 1, 2019, the Weatherford Parties and the commitment parties thereto (the “Commitment Parties”) entered into a Backstop Commitment Agreement. Pursuant to the terms of the Debtors’ Plan, and subject to approval by the Bankruptcy Court in connection with confirmation of the Plan, the Company intends to offer to holders of its existing unsecured notes, including the Commitment Parties, subscription rights to purchase the Tranche A Notes in aggregate principal amount of $1.25 billion, upon the Company’s emergence from bankruptcy.

Subject to the terms and conditions contained in the Backstop Commitment Agreement, the Consenting Creditors have committed to purchase any Tranche A Notes that are not duly subscribed for pursuant to the rights offering at a price equal to $1,000 per $1,000 in principal amount of the Tranche A Notes purchased by such Commitment Party. As consideration for the

commitment by the Commitment Parties, the Weatherford Parties made an aggregate payment in an amount equal to $62.5 million in cash to the Commitment Parties. Except under certain circumstances set forth in the Backstop Commitment Agreement, such payment is non-refundable, regardless of the principal amount of unsubscribed Tranche A Notes (if any) purchased by the Commitment Parties.

The transactions contemplated by the Backstop Commitment Agreement are conditioned upon the satisfaction or waiver of customary conditions for transactions of this nature, including, without limitation, that (i) the Bankruptcy Court shall have approved the rights offering, (ii) the Bankruptcy Court shall have confirmed the Plan and (iii) the rights offering shall have been conducted, in all material respects, in accordance with the approval of the Bankruptcy Court, the Plan and the Backstop Commitment Agreement attached as an exhibit thereto.

Debtor-in-Possession Credit Agreement

On July 3, 2019, the Weatherford Parties entered into a senior secured superpriority debtor-in-possession credit agreement (the “DIP Credit Agreement”). The DIP Credit Agreement has two debtor-in-possession (“DIP”) facilities to provide liquidity during the pendency of the Cases. The facilities consist of (a) a DIP revolving credit facility in the principal amount of up to $750 million provided by banks or other lenders and (b) a DIP term loan facility in the amount of up to $1.0 billion, which is fully backstopped by the Consenting Creditors. The DIP Credit Agreement will mature on the earlier of (i) the date that is 12 months after the Weatherford Parties’ entry into the DIP Credit Agreement or (ii) the date of completion of the Transaction. The DIP Credit Agreement bears interest (i) with respect to Eurodollar borrowings, based on an adjusted LIBOR rate plus an applicable margin of 3.00%, with a 0.00% LIBOR floor and (ii) with respect to alternate base rate borrowings, a base rate plus an applicable margin of 2.00%. In addition to paying interest on outstanding principal amounts under the DIP Credit Agreement, the Debtors will be required to pay an unused commitment fee to the revolving facility lenders in respect of the unutilized DIP revolving facility commitments at a rate equal to 0.375% per annum on the average daily amount of the unutilized revolving facility commitments.

The DIP Credit Agreement has a minimum liquidity covenant of $150 million and is secured by substantially all the personal assets and properties of the Debtors and certain of their subsidiaries. The DIP Credit Agreement is also guaranteed on an unsecured basis by certain other subsidiaries of the Debtors.

On July 3, 2019, the Debtors borrowed approximately $1.4 billion under the DIP Credit Agreement and the proceeds of the borrowings under the DIP Credit Agreement were used to repay certain prepetition indebtedness, cash collateralize certain obligations with respect to letters of credit and similar instruments and finance the working capital needs and general corporate purposes of the Debtors and certain of their subsidiaries. On July 3, 2019, the Company repaid all outstanding amounts due under the secured Term Loan Agreement and 364-Day Credit Agreement totaling approximately $616 million with borrowings from our DIP Credit Agreement. In addition, we cash collateralized approximately $271 million of letters of credit and similar instruments with borrowings from the DIP Credit Agreement. See “Note 11 – Short-term Borrowings and Other Debt Obligations” for additional details.

Prepetition Charges

Expenses, gains and losses that are realized or incurred before July 1, 2019 and in relation to the Cases are recorded under the caption “Prepetition Charges” on our Condensed Consolidated Statements of Operations. These charges were $76 million in the second quarter ended June 30, 2019 and $86 million for the six months ended June 30, 2019, and primarily consisted of professional and other fees related to the Cases.

Liquidity Concerns and Actions to Address Liquidity Needs; Going Concern

Our bond and share price decline, as well as our declining credit ratings, have over time increased the level of uncertainty in our business and have impacted various key stakeholders, including our employees, our customers and suppliers, and our key lenders. Continued weak industry conditions have negatively impacted our results of operations and cash flows and may continue to do so in the future. In order to decrease our level of indebtedness and maintain the liquidity at levels we believed would be sufficient to meet our commitments, we undertook a number of actions, including minimizing capital expenditures and further reducing our recurring operating expenses. Ultimately, we concluded, even after taking these actions, we would not have sufficient liquidity to satisfy our debt service obligations and meet other financial obligations as they came due. As a result, on May 10, 2019, we announced the Company’s execution of the RSA and on July 1, 2019 the Debtors filed the Cases. We expect the DIP Credit Agreement should provide sufficient liquidity for the Company during the pendency of the Cases.

Industry conditions and the risks and uncertainties associated with the Cases, raise substantial doubt about our ability to continue as a going concern. The consolidated financial statements have been prepared in conformity with U.S. GAAP which contemplate the continuation of the Company as a going concern. There are no assurances that the Transaction as described in the RSA and the Plan will be completed successfully.

As of June 30, 2019, our unaudited Condensed Consolidated Financial Statements do not include any adjustments that might be necessary should we be unable to continue as a going concern. In addition, our unaudited Condensed Consolidated Financial Statements do not reflect any adjustments related to bankruptcy or liquidation accounting.

Appeal of New York Stock Exchange Determination to Delist our Ordinary Shares

Our ordinary shares are registered on the New York Stock Exchange (the “NYSE”) and were previously traded on the NYSE under the symbol “WFT.” As a result of our failure to satisfy the continued listing requirements of the NYSE, on May 13, 2019, the NYSE suspended trading in our ordinary shares and commenced procedures to delist us, which the Company has appealed. Following the NYSE’s suspension of trading of our ordinary shares, the Company’s ordinary shares commenced trading on the OTC Bulletin Board or “pink sheets” market on May 14, 2019 under the symbol “WFTIF.” After filing the Cases on July 1, 2019, our ordinary shares began trading under the symbol “WFTIQ.”

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

New Accounting Pronouncements

Accounting Changes

Effective January 1, 2019, we adopted Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842) issued by the Financial Accounting Standards Board (“FASB”) in February 2016 and the series of related updates that followed (collectively referred to as “Topic 842”), which requires a lessee to recognize a ROU lease asset and lease liability for all qualifying leases with terms longer than twelve months on the balance sheet, including those classified as operating leases under previously existing U.S. GAAP. The ASU also changes the definition of a lease and requires expanded quantitative and qualitative disclosures for both lessees and lessors.

We elected to adopt Topic 842 using the modified retrospective approach. As such, comparative financial information for prior periods has not been restated and continues to be reported under the previous accounting guidance for those periods. We did not elect the hindsight practical expedient. See “Note 10 – Leases” for additional lease information and practical expedients elected.

The impact of Topic 842 on our consolidated balance sheet beginning January 1, 2019 was through the recognition of ROU assets and lease liabilities for operating leases, while our accounting for finance leases (previously referred to as capital leases) remains substantially unchanged. Amounts recognized at January 1, 2019 for operating leases were as follows:



(Dollars in millions)	Balance at January 1, 2019
Assets and Liabilities:
Other Non-Current Assets	$	288
Other Current Liabilities	92
Other Non-Current Liabilities	219

In February 2018, the FASB issued ASU 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which permits a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. We adopted this standard in the first quarter of 2019 and an election was not made to reclassify the income tax effects of the Tax Cuts and Jobs Act from Accumulated Other Comprehensive Income to retained earnings.

In July 2017, the FASB issued ASU 2017-11, Part I Accounting for Certain Financial Instruments with Down Round Features, which amends the accounting for certain equity-linked financial instruments and states a down round feature no longer precludes equity classification when assessing whether the instrument is indexed to an entity’s own stock. For an equity-linked financial instrument no longer accounted for as a liability at fair value, the amendments require a down round to be treated as a dividend and as a reduction of income available to ordinary shareholders in basic earnings per share. We adopted this standard in the first

quarter of 2019 on a retrospective basis and the adoption did not have a significant impact on our Condensed Consolidated Financial Statements.

Accounting Standards Issued Not Yet Adopted

In August 2018, the FASB issued ASU 2018-14, Compensation — Retirement Benefits — Defined Benefit Plans — General (Subtopic 715-20): Disclosure Framework — Changes to the Disclosure Requirements for Defined Benefit Plans, which makes minor changes to the disclosure requirements for employers that sponsor defined benefit pension and other postretirement benefit plans. The ASU is effective for the fiscal year ending December 31, 2020, but early adoption is permitted. The ASU is required to be applied retrospectively. This new standard will not have a significant impact on our Condensed Consolidated Financial Statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement, which eliminates, adds and modifies certain disclosure requirements for fair value measurements as part of its disclosure framework project. The ASU is effective beginning with the first quarter of 2020, and early adoption is permitted. The ASU is required to be applied retrospectively, except the new Level 3 disclosure requirements which are applied prospectively. We evaluated the impact of this new standard and concluded that the adoption of the ASU will not have a significant impact on our Condensed Consolidated Financial Statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which replaces the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to determine credit loss estimates. The guidance requires entities to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. The updated guidance applies to (i) loans, accounts receivable, trade receivables, and other financial assets measured at amortized cost, (ii) loan commitments and other off-balance sheet credit exposures, (iii) debt securities and other financial assets measured at fair value through other comprehensive income, and (iv) beneficial interests in securitized financial assets. The amended guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. We will adopt the new standard on the effective date of January 1, 2020 and are evaluating the effect, if any, that the guidance will have on our Condensed Consolidated Financial Statements and related disclosures.

Accounts Receivable Factoring and Other Receivables	Jun. 30, 2019
Receivables [Abstract]
Accounts Receivable Factoring and Other Receivables	Accounts Receivable Factoring From time to time, we participate in factoring arrangements to sell accounts receivable to third-party financial institutions. In the first six months of 2019, we sold accounts receivable of $162 million and recognized a loss of $1 million on these sales. We received cash proceeds totaling $152 million. In the first six months of 2018, we sold accounts receivable of $188 million and recognized a loss of $1 million. We received cash proceeds totaling $181 million. Our factoring transactions in the first six months of 2019 and 2018 were recognized as sales, and the proceeds are included as operating cash flows in our Condensed Consolidated Statements of Cash Flows. Our accounts receivable factoring arrangements are subject to additional limitations as result of entering into the DIP Credit Agreement and Credit Agreement Forbearance Agreement, where (a) net cash proceeds from U.S. and Canadian entities will pay down the DIP Credit Agreement and (b) net cash proceeds from other countries up to $75 million in a calendar quarter can be retained for the Company (with any excess to prepay the DIP Credit Agreement). This factoring limitation begins in the third quarter of 2019.

- Definition

The entire disclosure for claims held for amounts due a entity, excluding financing receivables. Examples include, but are not limited to, trade accounts receivables, notes receivables, loans receivables. Includes disclosure for allowance for credit losses.

Business Combinations and Divestitures	Jun. 30, 2019
Business Combinations [Abstract]
Business Combinations and Divestitures	Business Combinations and Divestitures Acquisitions In the first six months of 2019, we made no acquisitions of businesses. In the first quarter of 2018, we acquired the remaining 50% equity interest in our Qatari joint venture that we previously accounted for as an equity method investment and consolidated the entity. The joint venture was established in 2008 to provide energy related services required for the drilling and completion of oil and gas wells at onshore and offshore locations within the State of Qatar. The total consideration to purchase the remaining equity interest was $87 million, which is comprised of a cash consideration of $72 million and an estimated contingent consideration of $15 million related to services the Qatari entity will render under new contracts. Of the $72 million in cash consideration, $48 million was paid in accordance with closing terms through the joint venture, with the remaining payment of $24 million to be paid two years from closing, in 2020. As a result of this step acquisition transaction with a change in control, we remeasured our previously held equity investment to fair value and recognized a $12 million gain. The Level 3 fair value of the acquisition was determined using an income approach. Divestitures On April 30, 2019, we completed the sale of our Reservoir Solutions business, also known as our laboratory services business to Oil & Gas Labs, LLC, an affiliate of CSL Capital Management, L.P., for an aggregate purchase price of $206 million in cash, subject to escrow release and customary post-closing working capital adjustments. The business disposition included our laboratory and geological analysis business, including the transfer of substantially all personnel and associated contracts related to the business. We recognized a gain of $117 million and divested a carrying amount of $61 million in net assets previously included in held for sale. On April 30, 2019, we completed the sale of our surface data logging business to Excellence Logging for $50 million in total consideration, subject to customary post-closing working capital adjustments. The business disposition included our surface data logging equipment, technology and associated contracts related to the business. We recognized an insignificant loss and divested a carrying amount of $34 million in net assets previously included in held for sale. In the first quarter of 2019, we completed the final closings in a series of closings pursuant to the purchase and sale agreements (“Agreements”) entered into with ADES International Holding Ltd. (“ADES”). We entered into the Agreements in July of 2018 to sell our land drilling rig operations in Algeria, Kuwait and Saudi Arabia, as well as two idle land rigs in Iraq, for an aggregate purchase price of $287.5 million. We received gross proceeds of $72 million in the first quarter of 2019. The ADES sale was subject to regulatory approvals, consents and other customary closing conditions, including potential adjustments based on working capital, net cash, loss or destruction of rigs and drilling contract backlog. The $11 million ADES advance of the purchase price held in escrow as of December 31, 2018 was released in the first quarter of 2019 as a credit towards the purchase price. The loss on the sale of land drilling rigs operations recognized in the first quarter of 2019 was $6 million and divested a carrying amount of $66 million in net assets previously included in held for sale. The Agreements divest a majority of our land drilling rig operations. In the first quarter of 2018, we completed the sale of our continuous sucker rod service business in Canada for a purchase price of $25 million and recognized a gain of $2 million. The carrying amounts of the major classes of assets divested total $23 million and included PP&E, allocated goodwill and inventory. Held for Sale During the second quarter of 2019, we reclassified remaining land drilling rigs held for sale assets of $53 million to assets held for use. We continue to pursue options to sell all of our remaining land drilling rigs operations however the time required to close the recent land drilling rigs sales indicate that we may not be able to conclude that a sale is probable to occur in an appropriate timeline. At June 30, 2019, assets qualifying as held for sale were insignificant. At December 31, 2018, assets qualifying as held for sale totaled $265 million and liabilities held for sale totaled $17 million. These amounts primarily consisted of our surface data logging and laboratory services business held for sale (which was completed as of April 30, 2019) and our remaining land drilling rigs operations held for sale (which the unsold portions were reclassified back to held for use in the second quarter of 2019).

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill

For the second quarter ended June 30, 2019, our interim goodwill impairment tests indicated that goodwill for our Asia and Middle East/North Africa (“MENA”) reporting units were impaired and as a result we incurred a goodwill impairment charge of $102 million. In the first quarter ended March 31, 2019 our interim goodwill impairment tests indicated that goodwill for our North America reporting unit was impaired and as a result we incurred a goodwill impairment charge of $229 million. The impairment indicators during the first and second quarters of 2019 were a result of lower activity levels and lower exploration and production capital spending that resulted in a decline in drilling activity and forecasted growth in North America, Asia and MENA reporting units. Our cumulative impairment loss for goodwill was $3.0 billion at June 30, 2019. The changes in the carrying amount of goodwill by reporting segment at June 30, 2019, are presented in the following table.



(Dollars in millions)	Western Hemisphere			Eastern Hemisphere			Total

Goodwill Impairment Assessment Factors

We perform an impairment test for goodwill annually as of October 1 or more frequently if indicators of potential impairment exist that would more likely than not reduce the fair value of the reporting unit below its carrying value. In assessing the possibility that a reporting unit’s fair value has been reduced below its carrying amount due to the occurrence of events or circumstances

between annual impairment testing dates, we consider all available evidence, including, but not limited to, (i) the results of our impairment testing at the prior annual impairment testing date, in particular the magnitude of the excess of fair value over carrying value, (ii) changes in market conditions, (iii) downward revisions to internal forecasts, and the magnitude thereof, if any, (iv) decline in our market capitalization below our book value, and the magnitude and duration of those declines, if any.

Our share price has historically experienced volatility as a result of industry-wide and macroeconomic factors, including global oil prices and rig counts. In addition, our financial results and our inability to meet our Transformation Plan (as defined in “Note 9 – Transformation, Facility Restructuring and Severance Charges”) initiatives in the magnitude and desired time-frame, contributed to the NYSE suspension of the trading in our ordinary shares and commencement of procedures to delist our shares, which the Company has appealed. These circumstances, along with the filing of the Cases, prompted us to evaluate whether circumstances had changed that would more likely than not reduce the fair value of one or more of our reporting units below their carrying amount as of June 30, 2019. While conducting this evaluation, we considered macroeconomic and industry conditions, including the outlook for exploration and production spending by our customers, the magnitude and declines in our market capitalization and overall financial performance of each of our reporting units. We also considered whether there were any changes in our long-term forecasts, which are impacted by assumptions about the future commodity pricing and supply and demand for our goods and services, all of which require considerable judgment in estimation.

For the second quarter ended June 30, 2019, our interim goodwill impairment tests indicated that goodwill for our Asia and MENA reporting units were impaired and as a result we incurred a goodwill impairment charge of $102 million. We impaired our entire balance of our MENA reporting unit by recognizing a $43 million impairment charge.

While we believe that we will continue to operate in the ordinary course during our bankruptcy process and upon emergence from Chapter 11 bankruptcy proceedings, our estimates of fair values are sensitive to inputs to the valuation approaches, including our forecasts of revenues and earnings growth. There can be no assurances that changes to our inputs would not result in a material impairment of goodwill.

Restructuring and Transformation Charges

Restructuring and Related Activities [Abstract]

Restructuring Charges

Transformation, Facility Restructuring and Severance Charges

Due to the highly competitive nature of our business and the continuing losses we incurred over the last few years, we continue to reduce our overall cost structure and workforce to better align our business with current activity levels. The ongoing transformation plan, which began in 2018 and is expected to extend significantly beyond the originally planned year-end 2019 target (the “Transformation Plan”), includes a workforce reduction, organization restructure, facility consolidations and other cost reduction measures and efficiency initiatives across our geographic regions.

The cost reduction plans before the Transformation Plan (“Prior Plans”) included a workforce reduction and other cost reduction measures initiated across our geographic regions due to the ongoing low levels of exploration and production spending. The plans were initiated to reduce our overall cost structure and workforce to better align with current activity levels of exploration and production.

In connection with the Transformation Plan, we recognized restructuring and transformation charges of $20 million and $40 million in the second quarter and first six months of 2019, respectively, which include severance charges of $1 million and $3 million, respectively, other restructuring charges of $15 million and $29 million, respectively, and restructuring related asset charges of $4 million and $8 million, respectively. Other restructuring charges in both periods included contract termination costs, relocation and other associated costs.

In the second quarter and first six months of 2018 we recognized restructuring charges of $38 million and $63 million, respectively, which included severance charges of $29 million and $40 million, respectively and other restructuring charges of $9 million and $23 million, respectively.

The following tables present the components of restructuring charges by segment for the second quarter and first six months ended June 30, 2019 and 2018.

Leases (Notes)

6 Months Ended

Jun. 30, 2019

Leases [Abstract]

Leases

We lease certain facilities, land, vehicles, and equipment. Leases with an initial term of 12 months or less are not recorded on the balance sheet (including short-term sale leaseback transactions); we recognize lease expense for these leases on a straight-line basis over the lease term.

Beginning January 1, 2019, operating ROU assets and operating lease liabilities are recognized based on the present value of lease payments over the lease term at commencement date. Operating leases in effect prior to January 1, 2019 were recognized at the present value of the remaining payments on the remaining lease term as of January 1, 2019. We determine if an arrangement is classified as a lease at inception of the arrangement. As most of our leases do not provide an implicit rate of return, we use our incremental borrowing rate, together with the lease term information available at commencement date of the lease, in determining the present value of lease payments, which is updated on a quarterly basis. For adoption of Topic 842 we used the December 31, 2018 incremental borrowing rate, for operating leases that commenced prior to December 31, 2018. We have data center lease agreements with lease and non-lease components which are accounted for separately, while for the remainder of our agreements we have elected the practical expedient to account for lease and non-lease components as a single lease component. For certain equipment leases, such as copiers and vehicles, we account for the leases under a portfolio method. Operating lease payments include related options to extend or terminate lease terms that are reasonably certain of being exercised.

The unmanned equipment that we lease to customers as operating leases consists primarily of drilling rental tools and artificial lift pumping equipment. These equipment rental revenues are generally provided based on call-out work orders that include fixed per unit prices and are derived from short-term contracts. See “Note 18 – Revenues” for additional details on our equipment rental revenues.

Finance leases are recorded net of $48 million in accumulated amortization as of June 30, 2019.

Revolving Credit Agreements and Term Loan Agreement

At June 30, 2019, we have two revolving credit agreements with total commitments of $846 million, comprised of an unsecured senior revolving credit agreement (the “A&R Credit Agreement”) in the amount of $529 million, and a Secured Second Lien 364-Day Revolving Credit Agreement (the “364-Day Credit Agreement” and, together with the A&R Credit Agreement, the “Revolving Credit Agreements”) in the amount of $317 million. At June 30, 2019, we have principal borrowings of $298 million under the Term Loan Agreement. We collectively refer to our Revolving Credit Agreements and Term Loan Agreement as the “Credit Agreements.” Under the terms of the A&R Credit Agreement, commitments of $226 million from non-extending lenders matured on July 12, 2019 and commitments of $303 million from extending lenders will mature on July 13, 2020.

The Term Loan Agreement required a quarterly payment of $12.5 million plus interest that became due on June 30, 2019 and was unpaid as of June 30, 2019. On July 1, 2019, the Debtors and the Term Loan Lenders entered into a Term Loan Forbearance Agreement where the lenders agreed to forbear from exercising their rights and remedies available to them, including the right to accelerate any indebtedness, for a specified period of time.

Loans under the Credit Agreements were subject to varying interest rates based on whether the loan is a Eurodollar or alternate base rate loan. We also incurred a quarterly facility fee on the amount of the A&R Credit Agreement. For the three months ended June 30, 2019, the interest rate for the A&R Credit Agreement was LIBOR plus a margin rate of 3.55% for extending lenders and LIBOR plus a margin rate of 2.80% for non-extending lenders. For the three months ended June 30, 2019, the interest rate for borrowings under our Term Loan Agreement and 364-Day Credit Agreement were LIBOR plus a margin rate of 2.30% and LIBOR plus a margin rate of 3.05%, respectively.

Our Credit Agreements contain customary events of default, including in the event of our failure to comply with our financial covenants. We must also maintain a leverage ratio of no greater than 2.5 to 1, a leverage and letters of credit ratio of no greater than 3.5 to 1, an asset coverage ratio of at least 4.0 to 1 and a current asset coverage ratio of at least 2.1 to 1, in each case with the terms and definitions for the ratios as provided in the Credit Agreements. The Term Loan Agreement and 364-Day Credit Agreement require us to pledge assets as collateral in order to borrow under the credit facility. These were repaid in full on July 3, 2019 as described earlier. The filing of the Cases on July 1, 2019, constitutes an event of default that accelerated the Company’s obligations under each of the Credit Agreements, however forbearance agreements were obtained for each agreement and efforts to enforce payments under the Credit Agreements are automatically stayed as a result of the Cases. See “Note 2 – Chapter 11 Proceedings and Ability to Continue as a Going Concern” for additional details regarding how the Plan and Transaction will impact the Credit Agreements.

On July 3, 2019, we repaid the outstanding principal and interest remaining under the Term Loan Agreement and 364-Day Credit Agreement with borrowings from our DIP Credit Agreement, leaving only the A&R Credit Agreement outstanding. We have reclassified the Term Loan Agreement balance to current maturities of long-term debt as of June 30, 2019. See “Note 2 – Chapter 11 Proceedings and Ability to Continue as a Going Concern” for additional details regarding how the Plan and Transaction will impact the Credit Agreements.

Senior Notes and Tender Offers

The Debtors’ 7.75% Senior Notes due 2021, 8.25% Senior Notes due 2023 and 6.80% Senior Notes due 2037 (together, the “Certain Senior Notes”) provide for an aggregate $69 million interest payment that became due on June 15, 2019. The applicable indenture governing the Certain Senior Notes provides a 30-day grace period that extended the latest date for making this interest payment to July 16, 2019, before an event of default will occur under the applicable indenture. The Debtors elected to not make this interest payment on the due date and to utilize the 30-day grace period provided by the indentures. As of June 30, 2019, there was no event of default. As a result of filing the Cases on July 1, 2019, an event of default occurred under each indenture governing

the unsecured notes, which automatically accelerated maturity of the principal, plus any accrued and unpaid interest, on such series of unsecured notes and certain other obligations of the Debtors. Any efforts to enforce such payment obligations under the unsecured notes or other accelerated obligations of the Debtors are automatically stayed as a result of the Cases, and the creditors’ rights of enforcement in respect of the unsecured notes and other accelerated obligations of the Debtors are subject to the applicable provisions of the Bankruptcy Code. The interest and principal on this indebtedness remains unpaid as of this report date.

In February 2018, we issued $600 million in aggregate principal amount of our 9.875% senior notes due 2025. We used part of the proceeds from our debt offering to repay in full our 6.00% senior notes due March 2018 and to fund a concurrent tender offer to purchase for cash any and all of our 9.625% senior notes due 2019. We settled the tender offer in cash for the amount of $475 million, retiring an aggregate face value of $425 million and accrued interest of $20 million. In April 2018, we repaid the remaining principal outstanding on an early redemption of the bond. We recognized a cumulative loss of $34 million on these transactions in “Bond Tender and Call Premium” on the accompanying Condensed Consolidated Statements of Operations.

Other Short-term Arrangements and Debt Activity

We have short-term borrowings with various domestic and international institutions pursuant to uncommitted credit facilities. At June 30, 2019, we had no short-term borrowings under these arrangements. In addition, we had $247 million of letters of credit under various uncommitted facilities and $166 million of letters of credit under the A&R Credit Agreement. At June 30, 2019, we have cash collateralized $113 million of our letters of credit, which is included “Cash and Cash Equivalents” in the accompanying Condensed Consolidated Balance Sheets. On July 3, 2019, we cash collateralized approximately $271 million of letters of credit and similar instruments with borrowings from the DIP Credit Agreement. See “Note 2 – Chapter 11 Proceedings and Ability to Continue as a Going Concern” for additional details.

Fair Value of Short and Long-term Borrowings

The carrying value of our short-term borrowings approximates their fair value due to their short maturities. These short-term borrowings are classified as Level 2 in the fair value hierarchy.

The fair value of our long-term debt fluctuates with changes in applicable interest rates among other factors including the events occurring after releasing our first quarter 2019 Form 10-Q (see “Note 2 – Chapter 11 Proceedings and Ability to Continue as a Going Concern” for additional details). Fair value will exceed carrying value when the current market interest rate is lower than the interest rate at which the debt was originally issued and will be less than the carrying value when the market rate is greater than the interest rate at which the debt was originally issued. The fair value of our long-term debt is classified as Level 2 in the fair value hierarchy and is established based on observable inputs in less active markets. The discussion on fair value is continued at “Note 12 – Fair Value of Financial Instruments, Assets and Other Assets.” The fair value and carrying value of our senior notes were as follows:



(Dollars in millions)	June 30, 2019		December 31, 2018
Fair Value	$	3,855	$	4,455
Carrying Value	7,304		7,285

Fair Value of Financial Instruments	Jun. 30, 2019
Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments, Assets and Other Assets Financial Instruments and Other Assets Measured and Recognized at Fair Value We estimate fair value at a price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the principal market for the asset or liability. Our valuation techniques require inputs that we categorize using a three level hierarchy, from highest to lowest level of observable inputs. Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 inputs are quoted prices or other market data for similar assets and liabilities in active markets, or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based upon our own judgment and assumptions used to measure assets and liabilities at fair value. Classification of a financial asset or liability within the hierarchy is determined based on the lowest level of input that is significant to the fair value measurement. Other than the derivative instruments discussed in “Note 13 – Derivative Instruments,” we had no other material assets or liabilities measured and recognized at fair value on a recurring basis at June 30, 2019 and December 31, 2018. Fair Value of Other Financial Instruments Our other financial instruments include cash and cash equivalents, accounts receivable, accounts payable, held-to-maturity investments, short-term borrowings and long-term debt. The carrying value of our cash and cash equivalents, accounts receivable, accounts payable, and short-term borrowings approximates their fair value due to their short maturities. These short-term borrowings are classified as Level 2 in the fair value hierarchy. The fair value of our short-term and long-term borrowings are discussed in “Note 11 – Short-term Borrowings and Other Debt Obligations.” As of June 30, 2019 and December 31, 2018, we have $50 million of held-to-maturity Angolan government bonds maturing in 2020. The carrying value of $50 million in both periods approximate their fair value as of June 30, 2019 and December 31, 2018. We assess whether an other-than-temporary impairment loss on the investment has occurred due to a decline in fair value or other market conditions. If the fair value of the security is below amortized cost and it is more likely than not that we will not be able to recover its amortized cost basis before its stated maturity, we will record an other-than-temporary impairment charge in the Condensed Consolidated Statements of Operations. Non-recurring Fair Value Measurements - Impairments In the first quarter and second quarter of 2019, our interim goodwill impairment tests indicated that our goodwill was impaired and as a result three of our reporting units was written down to its estimated fair value. The Level 3 fair values of our reporting units were determined using a combination of the income and market approach. The unobservable inputs to the income approach included each reporting unit’s estimated future cash flows and estimates of discount rates commensurate with the reporting unit’s risks. The market approach considered market multiples of comparable publicly traded companies to estimate fair value as a multiple of each reporting unit’s actual and forecasted earnings. See further discussion at “Note 8 – Goodwill.” In the three and six months ended 2019, we recognized long-lived asset impairments to write-down our assets to the lower of carrying amount or fair value less cost to sell for our land drilling rigs. The change in our expectations of the market’s recovery, in addition to successive negative operating cash flows in certain disposal asset groups represented an indicator that those assets will no longer be recoverable over their remaining useful lives. The Level 3 fair values of the long-lived assets were determined using a combination of the market and income approach. See further discussion at “Note 7 - Long-Lived Asset Impairments.”

Derivative Instruments	6 Months Ended
Derivative Instruments	Jun. 30, 2019
Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments From time to time, we may enter into derivative financial instrument transactions to manage or reduce our market risk. We manage our debt portfolio to achieve an overall desired position of fixed and floating rates, and we may employ interest rate swaps as a tool to achieve that goal. We enter into foreign currency forward contracts and cross-currency swap contracts to economically hedge our exposure to fluctuations in various foreign currencies. The major risks from interest rate derivatives include changes in the interest rates affecting the fair value of such instruments, potential increases in interest expense due to market increases in floating interest rates, changes in foreign exchange rates and the creditworthiness of the counterparties in such transactions. We monitor the creditworthiness of our counterparties, which are multinational commercial banks. The fair values of all our outstanding derivative instruments are determined using a model with Level 2 inputs including quoted market prices for contracts with similar terms and maturity dates. Warrant During the fourth quarter of 2016, in conjunction with the issuance of 84.5 million ordinary shares, we issued a warrant that gave the holder the option to acquire an additional 84.5 million ordinary shares. The exercise price on the warrant was $6.43 per share and was exercisable prior to May 21, 2019 (option period lapsed and was not exercised as of May 21, 2019). The warrant was carried at fair value on the Condensed Consolidated Balance Sheets and changes in the fair value were reported through earnings. The warrant participated in dividends and other distributions as if the shares subject to the warrants were outstanding. In addition, the warrant permitted early redemption due to a change in control. The warrant fair value was considered a Level 2 valuation and was estimated using the Black Scholes valuation model. Inputs to the model included Weatherford’s share price, volatility of our share price, and the risk-free interest rate. The fair value of the warrant was zero at June 30, 2019 and December 31, 2018. We recognized an insignificant amount of unrealized gain in the six months ended June 30, 2019 prior to its expiration and unrealized gains of $10 million and $56 million for the second quarter and six months ended June 30, 2018, respectively, with changes in fair value of the warrants recorded each period in “Warrant Fair Value Adjustment” on the accompanying Condensed Consolidated Statements of Operations. Foreign Currency Forward Contracts At June 30, 2019 and December 31, 2018, we had an estimated net current liability for the fair value of our outstanding foreign currency forward contracts of $1 million and $4 million, respectively, with notional amounts aggregating to $585 million and $435 million, respectively. These foreign currency forward contracts are not designated as hedges under ASU 2014-03, Derivatives and Hedging (Topic 815), and their notional amounts do not generally represent amounts exchanged by the parties and thus are not a measure of the cash requirements related to these contracts or of any possible loss exposure. The amounts actually exchanged at maturity are calculated by reference to the notional amounts and by other terms of the derivative contracts, such as exchange rates. The changes in fair value of the contracts are recorded each period in “Other Expense, Net” on the accompanying Condensed Consolidated Statements of Operations. For the second quarter ended June 30, 2019 and June 30, 2018, we had a loss on the foreign currency forward contracts of $2 million and a loss of foreign currency forward contracts of $1 million, respectively. For the six months ended June 30, 2019, we had a gain on the foreign currency forward contracts of $3 million and for the six months ended June 30, 2018, we had no gain or loss. Other Derivative Instruments We may use interest rate swaps to help mitigate our exposures related to changes in the fair values of fixed-rate debt and to mitigate our exposure to variability in forecasted cash flows due to changes in interest rates. As of June 30, 2019, we did not have any fair value or cash flow hedges designated under ASU 2014-03. In 2008, we entered into interest rate derivative instruments to hedge projected exposures to interest rates in anticipation of a debt offering. These hedges were terminated at the time of the issuance of the debt and the associated loss is being amortized from “Accumulated Other Comprehensive Loss” to interest expense over the remaining term of the debt. See “Note 15 – Shareholders' (Deficiency) Equity” for additional information.

Disputes, Litigation and Contingencies	6 Months Ended
Disputes, Litigation and Contingencies	Jun. 30, 2019
Commitments and Contingencies Disclosure [Abstract]
Disputes, Litigation and Contingencies	Disputes, Litigation and Contingencies Shareholder Litigation In 2010, three shareholder derivative actions were filed, purportedly on behalf of the Company, asserting breach of duty and other claims against certain then current and former officers and directors of the Company related to the United Nations oil-for-food program governing sales of goods into Iraq, the Foreign Corrupt Practices Act of 1977 and trade sanctions related to the U.S. government investigations disclosed in our SEC filings since 2007. Those shareholder derivative cases were filed in Harris County, Texas state court and consolidated under the caption Neff v. Brady, et al., No. 2010040764 (collectively referred to as the “Neff Case”). Other shareholder demand letters covering the same subject matter were received by the Company in early 2014, and a fourth shareholder derivative action was filed, purportedly on behalf of the Company, also asserting breach of duty and other claims against certain then current and former officers and directors of the Company related to the same subject matter as the Neff Case. That case, captioned Erste-Sparinvest KAG v. Duroc-Danner, et al., No. 201420933 (Harris County, Texas) was consolidated into the Neff Case in September 2014. A motion to dismiss was granted May 15, 2015, and an appeal was filed on June 15, 2015. Following briefing and oral argument, on June 29, 2017, the Texas Court of Appeals denied in part and granted in part the shareholders’ appeal. The Court ruled that the shareholders lacked standing to bring claims that arose prior to the Company’s redomestication to Switzerland in 2009 and upheld the dismissal of those claims. The Court reversed as premature the trial court’s dismissal of claims arising after the redomestication and remanded to the trial court for further proceedings. On February 1, 2018, the individual defendants and nominal defendant Weatherford filed a motion for summary judgment on the remaining claims in the case. On February 13, 2018, the trial court dismissed with prejudice certain directors for lack of jurisdiction. The plaintiffs have appealed the jurisdictional ruling and the parties have jointly moved for a stay of the case during the pendency of the appeal and the appeal is now stayed during the pendency of the Cases. We cannot reliably predict the outcome of the remaining claims, including the amount of any possible loss. Rapid Completions and Packers Plus Litigation Several subsidiaries of the Company are defendants in a patent infringement lawsuit filed by Rapid Completions LLC (“RC”) in U.S. District Court for the Eastern District of Texas on July 31, 2015. RC claims that we and other defendants are liable for infringement of seven U.S. patents related to specific downhole completion equipment and the methods of using such equipment. These patents have been assigned to Packers Plus Energy Services, Inc., a Canadian corporation (“Packers Plus”), and purportedly exclusively licensed to RC. RC is seeking a permanent injunction against further alleged infringement, unspecified damages for infringement, supplemental and enhanced damages, and additional relief such as attorneys’ fees. The Company has filed a counterclaim against Packers Plus, seeking declarations of non-infringement, invalidity, and unenforceability of the four patents that remain asserted against the Company on the grounds of inequitable conduct. The Company is seeking attorneys’ fees and costs incurred in the lawsuit. The litigation was stayed, pending resolution of inter partes reviews (“IPR”) of each of the four patents before the Patent Trial and Appeal Board (“PTAB”) of the U.S. Patent and Trademark Office (“USPTO”). On February 22, 2018, the PTAB issued IPR decisions finding that all of the claims of the ‘505, ‘634, and ‘774 patents that were challenged by the Company in the IPRs are invalid. On October 16, 2018, the PTAB issued an IPR decision finding that all of the claims of the ‘501 patent are invalid. RC appealed the decisions of the PTAB. On June 3, 2019, the Federal Circuit heard RC’s oral arguments on the appeal related to the ‘505, ‘634, and ‘774 patents and affirmed on June 6, 2019 the PTAB’s decision that the patents are invalid. We are awaiting the oral argument on RC’s appeal of the of the PTAB’s decision on the ‘501 patent. On October 14, 2015, Packers Plus and RC filed suit in Federal Court in Toronto, Canada against the Company and certain subsidiaries alleging infringement of a related Canadian patent and seeking unspecified damages and an accounting of the Company’s profits. Trial on the validity of the Canadian patent was completed in March 2017. On November 3, 2017, the Federal Court issued its decision, wherein it concluded that the defendants proved that the patent-in-suit was invalid and dismissed Packers Plus and RC’s claims of infringement. On January 5, 2018, Packers Plus and RC filed their Notice of Appeal. The Company filed its responsive brief in June 2018. The hearing of the appeal took place on February 6, 2019, and on April 24, 2019, the appeal was dismissed in favor of Weatherford. Packers Plus and RC have filed an Application for Leave to the Supreme Court of Canada requesting that the Supreme Court hear their appeal from the appellate court’s decision. The Company will respond to the application by August 26, 2019. At this time, we believe it is unlikely that we will incur a loss related to the patent infringement matters, and therefore we have not accrued any loss provisions related to these matters. If one or more negative outcomes were to occur in any case, the impact to our financial position, results of operations, or cash flows could be material. Other Disputes and Litigation In addition, we have certain claims, disputes and pending litigation for which we do not believe a negative outcome is probable or for which we can only estimate a range of liability. It is possible, however, that an unexpected judgment could be rendered against us, or we could decide to resolve a case or cases, that would result in liability that could be uninsured and beyond the amounts we currently have reserved and in some cases those losses could be material. If one or more negative outcomes were to occur relative to these matters, the aggregate impact to our financial condition could be material. Accrued litigation and settlements recorded in “Other Current Liabilities” on the accompanying Condensed Consolidated Balance Sheets as of June 30, 2019 and December 31, 2018 were $29 million and $29 million, respectively. Other Contingencies We have minimum purchase commitments related to a supply contract and maintain a liability at June 30, 2019 for expected penalties to be paid of $24 million in “Other Current Liabilities” on our Condensed Consolidated Balance Sheets. Our minimum obligation for these commitments at December 31, 2018 was $46 million, of which $22 million was recorded in “Other Current Liabilities” and $24 million was recorded in “Other Non-Current Liabilities” on our Condensed Consolidated Balance Sheets.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	General The accompanying unaudited Condensed Consolidated Financial Statements of Weatherford International plc (the “Company,” “Weatherford” or “Weatherford Ireland”) are prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and include all adjustments, consisting of normal recurring adjustments, which in our opinion, are considered necessary to present fairly our Condensed Consolidated Balance Sheets at June 30, 2019 and December 31, 2018, Condensed Consolidated Statements of Operations and Condensed Consolidated Statements of Comprehensive Loss for the three and six months ended June 30, 2019 and 2018 and Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2019 and 2018. When using phrases such as “we,” “us,” and “our,” the intent is to refer to Weatherford International plc, a public limited company organized under the law of Ireland, and its subsidiaries as a whole or on a regional basis, depending on the context in which the statements are made. Although we believe the disclosures in these financial statements are adequate, certain information relating to our organization and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted in this Form 10-Q pursuant to U.S. Securities and Exchange Commission (“SEC”) rules and regulations. These financial statements should be read in conjunction with the audited Consolidated Financial Statements for the year ended December 31, 2018 included in our Annual Report on Form 10-K. The results of operations for the three and six months ended June 30, 2019 are not necessarily indicative of the results expected for the year ending December 31, 2019 for which we expect to file the related Annual Report on Form 10-K as an accelerated filer, our first period affected by the change in filing status based on our public float as of the last business day of our second fiscal quarter of 2019. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements, the reported amounts of revenues and expenses during the reporting period, and disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our estimates and assumptions, including those related to uncollectible accounts receivable, lower of cost or net realizable value of inventories, assets and liabilities held for sale, derivative financial instruments, intangible assets and goodwill, property, plant and equipment (“PP&E”), right-of-use (“ROU”) lease assets, income taxes, accounting for long-term contracts, self-insurance, foreign currency exchange rates, lease liabilities, pension and post-retirement benefit plans, disputes, litigation, contingencies and share-based compensation. We base our estimates on historical experience, adjusted for current conditions if necessary, and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates. Principles of Consolidation We consolidate all wholly owned subsidiaries and controlled joint ventures. All material intercompany accounts and transactions have been eliminated in consolidation. Reclassifications Certain reclassifications of the financial statements and accompanying footnotes for the three and six months ended June 30, 2018 have been made to conform to the presentation for the three and six months ended June 30, 2019.

Long-Lived Asset Impairments	6 Months Ended
Long-Lived Asset Impairments	Jun. 30, 2019
Property, Plant and Equipment [Abstract]
Long-Lived Asset Impairments	Long-Lived Asset Impairments We recognized long-lived asset impairments of $13 million and $20 million, respectively, for the three and six months ended June 30, 2019, and $92 million for the three and six months ended June 30, 2018, to write-down our assets to the lower of carrying amount or fair value less cost to sell for our land drilling rigs. The impairments were primarily related to our Western Hemisphere segment in the second quarter of 2019 and Eastern Hemisphere in the first quarter of 2019. The impairments recognized for the three and six months ended June 30, 2018, were comprised of $37 million from our Western Hemisphere segment and $55 million from our Eastern Hemisphere segment. During the second quarter of 2019, we reclassified our remaining land drilling rigs assets back into held for use. The impairments were due to the sustained downturn in the oil and gas industry that resulted in us having to reassess our disposal groups for our land drilling rigs. The change in our expectations of the market’s recovery, in addition to successive negative operating cash flows in certain disposal asset groups represented an indicator that those assets will no longer be recoverable over their remaining useful lives. The Level 3 fair values of the long-lived assets were determined using a combination of the market and income approach. The market approach considered market sales values for similar assets. The unobservable inputs to the income approach included the assets’ estimated future cash flows and estimates of discount rates commensurate with the assets’ risks.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We have determined that because small changes in estimated ordinary annual income would result in significant changes in the estimated annual effective tax rate, the use of a discrete effective tax rate is appropriate for determining the quarterly provision for income taxes. The discrete method treats the year-to-date period as if it was the annual period and determines the income tax expense or benefit on that basis. We will continue to use this method each quarter until the annual effective tax rate method is deemed appropriate. For the second quarter and the first six months of 2019, we had a tax expense of $33 million and $45 million, respectively, on a loss before income taxes of $279 million and $744 million, respectively, compared to the second quarter and the first six months of 2018 tax expense of $26 million and $58 million, respectively on a loss before income taxes of $233 million and $443 million, respectively. The sum of goodwill impairment, prepetition charges, asset write-downs and other, transformation, facility restructuring and severance charges, and the net gain on sale of businesses resulted in no significant tax expense for the second quarter of 2019 and no significant tax benefit in the first six months of 2019, respectively. The tax expense for the second quarter and the first six months of 2019 and 2018 also includes withholding taxes, minimum taxes and deemed profit taxes that do not directly correlate to ordinary income or loss. We are routinely under tax examination in various jurisdictions. We cannot predict the timing or outcome regarding resolution of these tax examinations or if they will have a material impact on our financial statements. We continue to anticipate a possible reduction in the balance of uncertain tax positions of approximately $22 million in the next twelve months due to expiration of statutes of limitations, settlements and/or conclusions of tax examinations.

Leases [Abstract]
Lessee, Leases [Policy Text Block]	We lease certain facilities, land, vehicles, and equipment. Leases with an initial term of 12 months or less are not recorded on the balance sheet (including short-term sale leaseback transactions); we recognize lease expense for these leases on a straight-line basis over the lease term. Beginning January 1, 2019, operating ROU assets and operating lease liabilities are recognized based on the present value of lease payments over the lease term at commencement date. Operating leases in effect prior to January 1, 2019 were recognized at the present value of the remaining payments on the remaining lease term as of January 1, 2019. We determine if an arrangement is classified as a lease at inception of the arrangement. As most of our leases do not provide an implicit rate of return, we use our incremental borrowing rate, together with the lease term information available at commencement date of the lease, in determining the present value of lease payments, which is updated on a quarterly basis. For adoption of Topic 842 we used the December 31, 2018 incremental borrowing rate, for operating leases that commenced prior to December 31, 2018. We have data center lease agreements with lease and non-lease components which are accounted for separately, while for the remainder of our agreements we have elected the practical expedient to account for lease and non-lease components as a single lease component. For certain equipment leases, such as copiers and vehicles, we account for the leases under a portfolio method. Operating lease payments include related options to extend or terminate lease terms that are reasonably certain of being exercised. The unmanned equipment that we lease to customers as operating leases consists primarily of drilling rental tools and artificial lift pumping equipment. These equipment rental revenues are generally provided based on call-out work orders that include fixed per unit prices and are derived from short-term contracts. See “Note 18 – Revenues” for additional details on our equipment rental revenues.
