In response to continuing crude oil prices fluctuation and our anticipation of a lower level of exploration and production spending in 2016, we initiated an additional plan to reduce our overall costs and workforce to better align with anticipated activity levels. This cost reduction plan (the “2016 Plan”) included a workforce reduction and other cost reduction measures initiated across our geographic regions.

In connection with the 2016 Plan, we recognized restructuring charges of $51 million and $128 million in the second quarter and the first six months of 2016, respectively, which include termination (severance) benefits of $36 million and $108 million, respectively, and other restructuring charges of $15 million and $20 million, respectively. Other restructuring charges include contract termination costs, relocation and other associated costs.

In the fourth quarter of 2014, we announced a cost reduction plan (the “2015 Plan”), which included a worldwide workforce reduction and other cost reduction measures. In the second quarter and the first six months of 2015, we recognized restructuring charges of $69 million and $110 million for the 2015 Plan, which include termination (severance) benefits of $19 million and $59 million, respectively, and other restructuring charges of $50 million and $51 million, respectively. Other restructuring charges include contract termination costs, relocation and other associated costs.

The following tables present the components of the 2016 Plan and the 2015 Plan restructuring charges by segment for the second quarter and the first six months of 2016 and 2015.

Contractors [Abstract]
Percentage of Completion Contracts	Percentage-of-Completion Contracts We account for our long-term early production facility construction contracts in Iraq under the percentage-of-completion method. In the second quarter of 2016, we recognized an estimated project income of $52 million for our Zubair contract, and in the first six months of 2016 we are break-even. Cumulative estimated loss from the Iraq contracts was $532 million as of June 30, 2016. On May 26, 2016, we entered into an agreement with our customer containing the terms and conditions of the settlement on the Zubair contract. The settlement to be paid to us is a gross amount of $150 million, of which $62 million was received in the second quarter 2016, and includes variation order requests, claims for extension of time, payments of remaining contract milestones and new project completion timelines that resulted in relief from the liquidated damages provisions. Of the remaining gross settlement, we expect to collect $72 million in the second half of 2016 and the last $16 million in the first quarter of 2017. As of June 30, 2016, we have no claims revenue, and our percentage-of-completion project estimate includes $25 million in newly approved change orders and $32 million of back charges. Our net billings in excess of costs as of June 30, 2016 were $39 million and are shown in the “Other Current Liabilities” line on the Consolidated Balance Sheet. In the second quarter and the first six months of 2015, we recognized estimated project losses of $69 million and $27 million, respectively, related to our long-term early production facility construction contracts in Iraq accounted for under the percentage-of-completion method. Cumulative estimated losses on these projects were $406 million at June 30, 2015. As of June 30, 2015, our percentage-of-completion project estimates include $137 million of claims revenue and $21 million of back charges.

We received cash totaling $76 million and recognized a loss of $0.3 million. Our factoring transactions in the six months ended June 30, 2016 qualified for sale accounting under U.S. GAAP, and the proceeds are included in operating cash flows in our Condensed Consolidated Statements of Cash Flows. We did not sell any accounts receivable during the six months ended June 30, 2015. During the second quarter of 2016, we accepted a note with a face value of $120 million from Petroleos de Venezuela, S.A. (“PDVSA”) in exchange for $120 million in trade receivables. The note has a three year term at a 6.5% stated interest rate. We may decide to sell this note in the future and have classified the note in “Other Non-Current Assets” on the accompanying Condensed Consolidated Balance Sheets. We carry the note at lower of cost or fair value and recognized a loss of $84 million to adjust the note to fair value.

Revolving Credit Facility and Secured Term Loan Agreement

On May 4, 2016, we entered into an amended and restated revolving credit facility (the “A&R Credit Agreement”) in the amount of $1.38 billion and a $500 million secured term loan agreement (the “Term Loan Agreement” and collectively with the A&R Credit Agreement, the “Credit Agreements”). For lenders that have agreed to extend their commitments (“extending lenders”), the A&R Credit Agreement matures in July of 2019. For lenders that did not agree to extend their commitments (such lenders, representing $229 million, the “non-extending lenders”), the A&R Credit Agreement matures in July of 2017. The Term Loan Agreement matures on July of 2020, and beginning September 30, 2016, a principal repayment of $12.5 million is required on the last day of each quarter. At June 30, 2016, we had $1.31 billion available for borrowing under our A&R Credit Agreement and there were $26 million in outstanding letters of credit.

Loans under the Credit Agreements are subject to varying rates of interest based on whether the loan is a Eurodollar loan or an alternate base rate loan. We also incur a quarterly facility fee on the amount of the A&R Credit Agreement. See Note 8 – Long-term Debt, for information related to interest rate applicable for the Term Loan Agreement.

Eurodollar Loans. Eurodollar loans bear interest at the Eurodollar rate, which is LIBOR, plus the applicable margin. The applicable margin for Eurodollar loans under the A&R Credit Agreement depends on whether the lender is an extending lender or a non-extending lender. For non-extending lenders, the applicable margin under the A&R Credit Agreement ranges from 0.75% to 1.925% depending on our credit rating, and for extending lenders under the A&R Credit Agreement the applicable margin ranges from 1.925% to 3.7% depending on our leverage ratio.

Alternate Base Rate Loans. Alternate base rate loans bear interest at the alternate base rate plus the applicable margin. The applicable margin for alternate base rate loans under the A&R Credit Agreement depends on whether the lender is an extending lender or a non-extending lender. For non-extending lenders, the applicable margin under the A&R Credit Agreement ranges from 0.0% to 0.925% depending on our credit rating, and for extending lenders the applicable margin under the A&R Credit Agreement ranges from 0.925% to 2.7% depending on our leverage ratio.

Borrowings under our A&R Credit Agreement may be repaid from time to time without penalty. Obligations under the Term Loan Agreement are secured by substantially all of our assets. In addition, obligations under the Credit Agreements are guaranteed by a material portion of our subsidiaries.

Our Credit Agreements contain covenants including, among others, the following:


•	a prohibition against incurring debt, subject to permitted exceptions;


•	a restriction on creating liens on our assets and the assets of our operating subsidiaries, subject to permitted exceptions;


•	restrictions on mergers or asset dispositions;


•	restrictions on use of proceeds, investments, transactions with affiliates, or change of principal business; and


•	maintenance of the following financial covenants:


1)	leverage ratio of no greater than 3 to 1 through December 31, 2016 and 2.5 to 1 thereafter until maturity. This ratio measures our indebtedness guaranteed by subsidiaries under the Credit Agreements and other guaranteed facilities to the trailing four quarters consolidated adjusted earnings before interest, taxes, depreciation, amortization and other specified charges (“EBITDA”);


2)	leverage and letters of credit ratio of no greater than 4 to 1 on or before December 31, 2016 and 3.5 to 1 thereafter calculated as our indebtedness guaranteed by subsidiaries under the Credit Agreements and other guaranteed facilities and all letters of credit to the trailing four quarters consolidated adjusted EBITDA; and


3)	asset coverage ratio of at least 4 to 1, which is calculated as our asset value to indebtedness guaranteed by subsidiaries under the Credit Agreements and other guaranteed facilities.

Our Credit Agreements contain customary events of default, including our failure to comply with the financial covenants described above. As of June 30, 2016, we were in compliance with these financial covenants.

On July 19, 2016, we amended these facilities to make minor changes and amendments to certain collateral provisions, negative covenants and related definitions, and to add an accordion feature to permit new and existing lenders to add up to a maximum of $250 million in additional commitments.

Other Short-Term Borrowings and Other Debt Activity

We have short-term borrowings with various domestic and international institutions pursuant to uncommitted credit facilities. At June 30, 2016, we had $73 million in short-term borrowings under these arrangements, primarily from overdraft facility borrowings. In the first six months of 2016, we repaid $180 million borrowed under a credit agreement that matured on March 20, 2016 and June 20, 2016. In addition, we had $590 million of letters of credit under various uncommitted facilities and $149 million of surety bonds, primarily performance bonds, issued by financial sureties against an indemnification from us at June 30, 2016.

At June 30, 2016, the current portion of long-term debt was primarily related to our 6.35% Senior Notes due 2017 and the current portion of our secured term loan and capital leases. Our 5.50% senior notes with a principal balance of $350 million were repaid in February 2016.

Secured Term Loan Agreement

On May 4, 2016, we entered into an amended and restated revolving credit facility (the “A&R Credit Agreement”) and borrowed $500 million under the “Term Loan Agreement.” The interest rate under the Term Loan Agreement is variable and is determined by our leverage ratio as of the most recent fiscal quarter, as either (1) the one-month London Interbank Offered Rate (“LIBOR”) plus a variable margin rate ranging from 1.425% to 3.20% or (2) the alternate base rate plus the applicable margin ranging from 0.425% to 2.20%. For the quarter ended June 30, 2016, the interest rate for the Term Loan Agreement was LIBOR plus a margin rate of 2.30% and the interest rate for the A&R Credit Agreement was LIBOR plus a margin rate of 2.80%. Beginning September 30, 2016, the Term Loan Agreement requires a principal repayment of $12.5 million on the last day of each quarter.

Exchangeable Senior Notes, Senior Notes and Tender Offers

We have issued various senior notes, all of which rank equally with our existing and future senior unsecured indebtedness, which have semi-annual interest payments and no sinking fund requirements.

Exchangeable Senior Notes

On June 7, 2016, we issued exchangeable notes with a par value of $1.265 billion and an interest rate of 5.875%. The notes have a conversion price of $7.74 per share and are exchangeable into a total of 163.4 million shares of the Company upon the occurrence of certain events or on or after January 1, 2021. The notes mature on July 1, 2021. We have the choice to settle the exchange of the notes in any combination of cash or shares. As of June 30, 2016, the if-converted value did not exceed the principal amount of the notes.

The exchange feature is reported with a carrying amount of $97 million in the line captioned “Capital in Excess of Par Value” on the accompanying Condensed Consolidated Balance Sheets. The debt component of the exchangeable notes has been reported separately in the line captioned “Long-term Debt” on the accompanying Condensed Consolidated Balance Sheets with a carrying value of $1.136 billion at June 30, 2016 net of remaining unamortized discount and debt issue costs of $129 million. The discount on the debt component will be amortized over the remaining maturity of the exchangeable notes at an effective interest rate of 8.4%. For the quarter ended June 30, 2016, interest expense on the notes was $6 million, of which $5 million related to accrued interest and $1 million related to amortization of the discount.

Senior Notes

On June 17, 2016, we issued $750 million in aggregate principal amount of 7.75% senior notes due 2021 and $750 million in aggregate principal amount of 8.25% senior notes due 2023.

Tender Offer and Early Retirement of Senior Notes

We commenced a cash tender offer on June 1, 2016 (and amended the offer on June 8, 2016 and June 10, 2016), which included an early tender option with an early settlement date of June 17, 2016 and an expiration date of June 30, 2016 with a final settlement date of July 1, 2016 to repurchase a portion of our 6.35% senior notes due 2017, 6.00% senior notes due 2018, 9.625% senior notes due 2019, and 5.125% senior notes due 2020. On June 17, 2016, we settled the early tender offer in cash in the amount of $1.972 billion, retiring an aggregate face value of senior notes tendered of $1.867 billion and accrued interest of $27 million. We recognized a cumulative loss of $78 million on these transactions in the line captioned “Bond Tender Premium, Net” on the accompanying Consolidated Statements of Operations. On June 30, 2016, we accepted additional tenders of an additional $2 million of debt, which we settled in cash on July 1, 2016.

In the first six months of 2015, through a series of open market transactions, we repurchased certain of our 4.5% senior notes, 5.95% senior notes, 6.5% senior notes and 6.75% senior notes with a total book value of $160 million. We recognized a cumulative gain of approximately $12 million on these transactions in the line captioned “Other, Net” on the accompanying Consolidated Statements of Operations.

Fair Value of Financial Instruments

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments, Assets and Equity Investments

Financial Instruments 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 10 – Derivative Instruments,” we had no other material assets or liabilities measured and recognized at fair value on a recurring basis at June 30, 2016 and December 31, 2015.

Fair Value of Other Financial Instruments

Our other financial instruments include short-term borrowings and long-term debt. The carrying value of our short-term borrowings approximates their fair value due to the short-term duration of the associated interest rate periods. 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. Fair value will generally exceed carrying value when the current market interest rate is lower than the interest rate at which the debt was originally issued and will generally be less than the carrying value when the market rate is greater than 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 fair value and carrying value of our senior notes were as follows:



(Dollars in millions)	June 30, 2016		December 31, 2015
Fair value	$	6,104	$	5,095
Carrying value	6,490		6,099

Non-recurring Fair Value Measurements

During the second quarter of 2015, long-lived pressure pumping assets and an equity investment were impaired and written down to their estimated fair values. The Level 3 fair value of the long-lived assets was determined using a combination of the cost approach and the market approach, which used inputs that included replacement costs (unobservable), physical deterioration estimates (unobservable), and market sales data for comparable assets. The equity investment Level 3 fair value was determined using an income based approach utilizing estimates of future cash flow, discount rate, long-term growth rate, and marketability discount, all of which were unobservable.

During the second quarter of 2016, we adjusted the note from PDVSA to its estimated fair value. The Level 3 fair value was estimated based on unobservable pricing indications.

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments

6 Months Ended

Jun. 30, 2016

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 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.

Fair Value Hedges

We may use interest rate swaps to help mitigate exposures related to changes in the fair values of fixed-rate debt. The interest rate swap is recorded at fair value with changes in fair value recorded in earnings. The carrying value of fixed-rate debt is also adjusted for changes in interest rates, with the changes in value recorded in earnings. After termination of the hedge, any discount or premium on the fixed-rate debt is amortized to interest expense over the remaining term of the debt. As of June 30, 2016, we did not have any fair value hedge designated.

As of June 30, 2016, we had net unamortized premiums on fixed-rate debt of $9 million associated with fair value hedge terminations. These premiums are being amortized over the remaining term of the originally hedged debt as a reduction in interest expense included in the line captioned “Interest Expense, Net” on the accompanying Condensed Consolidated Statements of Operations.

Cash Flow Hedges

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 Income (Loss) to interest expense over the remaining term of the debt. As of June 30, 2016, we had net unamortized losses of $9 million associated with our cash flow hedge terminations. As of June 30, 2016, we did not have any cash flow hedges designated.

Foreign Currency Derivative Instruments

At June 30, 2016 and December 31, 2015, we had outstanding foreign currency forward contracts with notional amounts aggregating to $1.6 billion and $1.7 billion, respectively. The notional amounts of our foreign currency forward contracts 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.

At June 30, 2016, we had no cross-currency swaps as we settled our cross-currency swap arrangements in the first quarter of 2015.

Our foreign currency derivatives are not designated as hedges under ASC 815, and the changes in fair value of the contracts are recorded each period in the line captioned “Other, Net” on the accompanying Condensed Consolidated Statements of Operations.

The total estimated fair values of our foreign currency forward contracts were as follows:

Income Taxes	6 Months Ended
Income Taxes	Jun. 30, 2016
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We estimate our annual effective tax rate based on year-to-date operating results and our forecast for the remainder of the year, by jurisdiction, and apply this rate to the year-to-date operating results. If our actual results, by jurisdiction, differ from the forecasted operating results, our effective tax rate can change, affecting the tax expense for both successive interim results as well as the annual tax results. For the second quarter and the first six months of 2016, we had a tax benefit of $102 million and $203 million, respectively, on a loss before income taxes of $664 million and $1.26 billion, respectively. Our results for the second quarter of 2016 include charges with no significant tax benefit principally related to $75 million of settlement charges, $78 million of bond tender premium, and $84 million of PDVSA note adjustment, partially offset by $52 million of Zubair project gains with no significant tax expense. Our results for the first six months of 2016 include charges with no significant tax benefit principally related to $140 million of settlement charges, $31 million of currency devaluation related to the Angolan kwanza, $78 million of bond tender premium, and $84 million of PDVSA note adjustment. We are continuously 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 $42 million in the next twelve months due to expiration of statutes of limitations, settlements and/or conclusions of tax examinations. For both the second quarter and the first six months of 2015, we had a $132 million tax benefit on a loss before income taxes of $615 million and $722 million, respectively. Our results for the second quarter of 2015 includes $112 million of litigation settlements, $69 million of project losses, $16 million of devaluation of the Angolan kwanza currency, $20 million of equity investment impairment and $69 million of restructuring charges, with no significant tax benefit. Our results for the first six months of 2015 includes $112 million of litigation settlements, $27 million of project losses, $42 million of currency devaluation, $20 million of equity investment impairment and $110 million of restructuring charges, with no significant tax benefit.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Earnings per Share

6 Months Ended

Jun. 30, 2016

Earnings Per Share [Abstract]

Earnings per Share

Basic earnings per share for all periods presented equals net income (loss) divided by the weighted average number of our shares outstanding during the period including participating securities. Diluted earnings (loss) per share is computed by dividing net income (loss) by the weighted average number of our shares outstanding during the period including participating securities, adjusted for the dilutive effect of our stock options, restricted shares and performance units.

The following discloses basic and diluted weighted average shares outstanding:



	Three Months Ended June 30,		Six Months Ended June 30,
(Shares in millions)	2016	2015	2016	2015
Basic and Diluted weighted average shares outstanding	899	778	856	778

Our basic and diluted weighted average shares outstanding for the periods presented are equivalent due to the net loss attributable to shareholders. Diluted weighted average shares outstanding for the second quarter and the first six months of 2016 and 2015 exclude potential shares for stock options, restricted shares, performance units and exchangeable notes outstanding as we have net losses for those periods, and their inclusion would be anti-dilutive.

The following table discloses the number of anti-dilutive shares excluded:



	Three Months Ended June 30,		Six Months Ended June 30,
(Shares in millions)	2016	2015	2016	2015
Anti-dilutive potential shares due to net loss	43	3	24	3

The performance units have a weighted average grant date fair value of $5.11 per share based on the Monte Carlo simulation method. The assumptions used in the Monte Carlo simulation included a risk-free rate of 0.80%, volatility of 68% and a zero dividend yield. As of June 30, 2016, there was $15 million of unrecognized compensation expense related to our performance units. This cost is expected to be recognized over a weighted average period of 2 years.

During the first six months of 2016, we also granted 2.9 million restricted shares at a weighted average grant date fair value of $6.31 per share. As of June 30, 2016, there was $96 million of unrecognized compensation expense related to our unvested restricted share grants.

Disputes, Litigation and Contingencies	6 Months Ended
Disputes, Litigation and Contingencies	Jun. 30, 2016
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 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 FCPA and trade sanctions related to the U.S. government investigations disclosed in our U.S. Securities and Exchange Commission (the “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 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, which remains pending, was filed on June 15, 2015. We cannot reliably predict the outcome of the appeal including the amount of any possible loss. If one or more negative outcomes were to occur relative to the Neff Case, the aggregate impact to our financial condition could be material. On June 30, 2015, we signed a stipulation to settle a shareholder securities class action captioned Freedman v. Weatherford International Ltd., et al., No. 1:12-cv-02121-LAK (S.D.N.Y.) for $120 million subject to notice to the class and court approval. The Freedman lawsuit had been filed in the U.S. District Court for the Southern District of New York in March 2012 and alleged that we and certain current and former officers of Weatherford violated the federal securities laws in connection with the restatements of the Company’s historical financial statements announced on February 21, 2012 and July 24, 2012. On November 4, 2015, the U.S. District Court for the Southern District of New York entered a final judgment and an order approving the settlement of the shareholder securities class action captioned Freedman v. Weatherford International Ltd., et al., No. 1:12-cv-02121-LAK (S.D.N.Y.). Pursuant to the settlement, we were required to pay $120 million in 2015, which was partially funded by insurance proceeds. There was no admission of liability or fault by any party in connection with the settlement. We are pursuing reimbursement from our insurance carriers and have recovered a total of $19 million of the settlement amount, of which $4 million have been recovered in 2016. U.S. Government and Other Investigations As previously disclosed, the SEC and the U.S. Department of Justice (“DOJ”) are also investigating the circumstances surrounding the material weakness in our internal control over financial reporting for income taxes that was disclosed in a notification of late filing on Form 12b-25 filed on March 1, 2011 and in current reports on Form 8-K filed on February 21, 2012 and on July 24, 2012 and the subsequent restatements of our historical financial statements. We are cooperating fully with these investigations and have been discussing a resolution with the SEC. During the first quarter 2016, after progress made in the continued discussion on potential resolutions with the SEC, we recorded a loss contingency in the amount of $65 million. In the second quarter 2016, our negotiations continued to advance, and we have increased our loss contingency to $140 million as our best estimate for the potential settlement of this matter. However, uncertainties remain pending the ultimate resolution of the investigation, and we may ultimately not reach a final settlement with the government. Additionally, we are aware of various disputes and potential claims and are a party in various litigation involving claims against us, including as a defendant in various employment claims alleging our failure to pay certain classes of workers overtime in compliance with the Fair Labor Standards Act for which we have arrived at an agreement during the second quarter 2016. Some of these disputes and claims are covered by insurance. For claims, disputes and pending litigation in which we believe a negative outcome is probable and a loss can be reasonably estimated, we have recorded a liability for the expected loss. These liabilities are immaterial to our financial condition and results of operations. 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. Other Contingencies We have a contractual residual value guarantee at June 30, 2016 of $28 million in the line captioned “Other Non-Current Liabilities” on the accompanying Consolidated Balance Sheets related to certain leased equipment in our North America pressure pumping business. We have supply contract related minimum purchase commitments and maintain a liability at June 30, 2016 of $135 million for expected penalties to be paid, of which $29 million is recorded in current liabilities and $106 million is recorded in other non-current liabilities on our Consolidated Balance Sheets.

New Accounting Pronouncements	Jun. 30, 2016
New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements Accounting Changes In April 2015, the Financial Accounting Standards Board (“FASB”) issued ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. We adopted ASU 2015-03 in the first quarter of 2016 retrospectively, which reduced Long-term debt and Other non-current assets by $27 million as of December 31, 2015. Accounting Standards Issued Not Yet Adopted In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected. The new standard applies to trade receivables and requires expected credit losses to be based on past events, current conditions and reasonable and supportable forecasts that affect the instrument’s collectability. The new standard will be effective for us beginning with the first quarter of 2020. Early adoption is permitted in 2019. We are evaluating the impact that this new standard will have on our Consolidated Financial Statements. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which impacts certain aspects of the accounting for share-based payment transactions. This update provides various transition requirements that include both prospective, modified retrospective and retrospective application guidance. The new standard will be effective for us beginning with the first quarter of 2017. Early adoption is permitted, but it must include all amendments in the same period. We are evaluating the impact that this new standard will have on our Condensed Consolidated Financial Statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which requires a lessee to recognize a lease asset and lease liability for most leases, including those classified as operating leases under existing GAAP. The ASU also changes the definition of a lease and requires expanded quantitative and qualitative disclosures for both lessees and lessors. The new standard will be effective for us beginning with the first quarter of 2019. Early application is permitted. The standard requires the use of a modified retrospective transition method and permits certain practical expedients to be applied. We are evaluating the effect that ASU 2016-02 will have on our Condensed Consolidated Financial Statements. In November 2015, the FASB issued ASU 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes, which eliminates the current requirement to present deferred tax liabilities and assets as current and noncurrent in a classified balance sheet. Instead, all deferred tax assets and liabilities will be required to be classified as noncurrent. The new standard will be effective for us beginning with the first quarter of 2017. Early adoption is permitted. We are evaluating the impact that this new standard will have on our Condensed Consolidated Financial Statements. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory, which requires inventory not measured using either the last in, first out (LIFO) or the retail inventory method to be measured at the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable cost of completion, disposal, and transportation. The new standard will be effective for us beginning with the first quarter of 2017, and will be applied prospectively. Early adoption is permitted. We do not expect the impact of our adoption to have a material effect on our Condensed Consolidated Financial Statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which will require an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 will replace most existing revenue recognition guidance in GAAP when it becomes effective. ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, deferred the effective date of ASU 2014-09 to annual and interim periods in fiscal years beginning after December 15, 2017. Earlier application is permitted only as of annual and interim reporting periods in fiscal years beginning after December 15, 2016. ASU 2014-09 permits either a retrospective application or a cumulative effect transition method. We have not yet selected the application date or a transition method, and we are currently evaluating the impact our adoption of this standard would have on our Condensed Consolidated Financial Statements.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Accounting	The accompanying unaudited Condensed Consolidated Financial Statements of Weatherford International plc (the “Company”) are prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and include all adjustments of a normal recurring nature which, in our opinion, are necessary to present fairly our Condensed Consolidated Balance Sheets at June 30, 2016 and December 31, 2015, Condensed Consolidated Statements of Operations and Condensed Consolidated Statements of Comprehensive Income (Loss) for the three and six months ended June 30, 2016 and 2015, and Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2016 and 2015. When referring to “Weatherford” and 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, 2015 included in our Annual Report on Form 10-K. The results of operations for the three and six months ended June 30, 2016 are not necessarily indicative of the results expected for the year ending December 31, 2016. 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 amounts 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 ongoing basis, we evaluate our estimates and assumptions, including those related to uncollectible accounts receivable, lower of cost or market of inventories, equity investments, intangible assets and goodwill, property, plant and equipment, income taxes, percentage-of-completion accounting for long-term contracts, self-insurance, foreign currency exchange rates, pension and post-retirement benefit plans, disputes, litigation, contingencies and share-based compensation. We base our estimates on historical experience 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	Principles of Consolidation We consolidate all wholly-owned subsidiaries, controlled joint ventures and variable interest entities where the Company has determined it is the primary beneficiary. Investments in affiliates in which we exercise significant influence over operating and financial policies are accounted for using the equity method. All material intercompany accounts and transactions have been eliminated in consolidation. Certain prior year amounts have been reclassified to conform to the current year presentation related to the adoption of new accounting standards. Net income and shareholders’ equity were not affected by these reclassifications. See “Note 17 – New Accounting Pronouncements” for additional details.

Accounting Policies [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements Accounting Changes In April 2015, the Financial Accounting Standards Board (“FASB”) issued ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. We adopted ASU 2015-03 in the first quarter of 2016 retrospectively, which reduced Long-term debt and Other non-current assets by $27 million as of December 31, 2015. Accounting Standards Issued Not Yet Adopted In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected. The new standard applies to trade receivables and requires expected credit losses to be based on past events, current conditions and reasonable and supportable forecasts that affect the instrument’s collectability. The new standard will be effective for us beginning with the first quarter of 2020. Early adoption is permitted in 2019. We are evaluating the impact that this new standard will have on our Consolidated Financial Statements. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which impacts certain aspects of the accounting for share-based payment transactions. This update provides various transition requirements that include both prospective, modified retrospective and retrospective application guidance. The new standard will be effective for us beginning with the first quarter of 2017. Early adoption is permitted, but it must include all amendments in the same period. We are evaluating the impact that this new standard will have on our Condensed Consolidated Financial Statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which requires a lessee to recognize a lease asset and lease liability for most leases, including those classified as operating leases under existing GAAP. The ASU also changes the definition of a lease and requires expanded quantitative and qualitative disclosures for both lessees and lessors. The new standard will be effective for us beginning with the first quarter of 2019. Early application is permitted. The standard requires the use of a modified retrospective transition method and permits certain practical expedients to be applied. We are evaluating the effect that ASU 2016-02 will have on our Condensed Consolidated Financial Statements. In November 2015, the FASB issued ASU 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes, which eliminates the current requirement to present deferred tax liabilities and assets as current and noncurrent in a classified balance sheet. Instead, all deferred tax assets and liabilities will be required to be classified as noncurrent. The new standard will be effective for us beginning with the first quarter of 2017. Early adoption is permitted. We are evaluating the impact that this new standard will have on our Condensed Consolidated Financial Statements. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory, which requires inventory not measured using either the last in, first out (LIFO) or the retail inventory method to be measured at the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable cost of completion, disposal, and transportation. The new standard will be effective for us beginning with the first quarter of 2017, and will be applied prospectively. Early adoption is permitted. We do not expect the impact of our adoption to have a material effect on our Condensed Consolidated Financial Statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which will require an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 will replace most existing revenue recognition guidance in GAAP when it becomes effective. ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, deferred the effective date of ASU 2014-09 to annual and interim periods in fiscal years beginning after December 15, 2017. Earlier application is permitted only as of annual and interim reporting periods in fiscal years beginning after December 15, 2016. ASU 2014-09 permits either a retrospective application or a cumulative effect transition method. We have not yet selected the application date or a transition method, and we are currently evaluating the impact our adoption of this standard would have on our Condensed Consolidated Financial Statements.
