Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	General The accompanying unaudited Condensed Consolidated Financial Statements of Weatherford International plc (the “Company,” or “Weatherford”) have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, certain information and disclosures normally included in our annual consolidated financial statements have been condensed or omitted. Therefore, these unaudited Condensed Consolidated Financial Statements should be read in conjunction with our audited Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2020 (“2020 Annual Report”). The preparation of the Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the Condensed Consolidated Financial Statements and the reported amounts of revenue and expenses during the reporting period. Ultimate results could differ from our estimates. In the opinion of management, the Condensed Consolidated Financial Statements reflect all adjustments (consisting of normal recurring adjustments) considered necessary by management to fairly state the results of operations, financial position and cash flows of Weatherford and its subsidiaries for the periods presented and are not necessarily indicative of the results that may be expected for a full year. Our financial statements have been prepared on a consolidated basis. Under this basis, our financial statements consolidate all wholly owned subsidiaries and controlled joint ventures. All intercompany accounts and transactions have been eliminated. Summary of Significant Accounting Policies

Property, Plant and Equipment [Abstract]
Long-Lived Asset Impairments and Other	Long-lived Asset Impairments We did not recognize any long-lived asset impairments in the three and nine months ended September 30, 2021. During the first half of 2020, the global economic and industry conditions resulting from the decline in demand and impact from the COVID-19 pandemic were identified as impairment indicators. As a result, we performed interim impairment assessments of our property, plant and equipment, definite-lived intangible assets, and right of use assets with the assistance of third-party valuation advisors. The fair values of our long-lived assets were determined using discounted cash flows under the income approach, a Level 3 fair value analysis. The income approach required significant assumptions to determine the fair value of an asset or asset group including the estimated discounted future cash flows, specifically the forecasted revenue, forecasted operating margins and the discount rate. Based on our impairment tests, we determined the carrying amount of certain long-lived assets exceeded their respective fair values and recognized long-lived asset impairments as summarized in “Note 2 – Impairments and Other Charges (Credits), Net.” and further presented by asset class and segment in the table below. We did not recognize any long-lived asset impairments in the third quarter of 2020.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill As of September 30, 2021 and December 31, 2020, we had no goodwill. The cumulative impairment loss for goodwill was $239 million, all of which was fully impaired in the first half of 2020. During 2020, based on our interim goodwill impairment assessments that determined the fair value of our reporting units were less than their carrying values, we recognized goodwill impairment charges presented in “Note 2 – Impairments and Other Charges (Credits), Net.” We identified impairment indicators as discussed in “Note 4 – Long-lived Asset Impairments” that triggered these interim quantitative goodwill assessments. The fair values of our reporting units were determined using a combination of the income approach and the market approach for comparable companies in our industry, a Level 3 fair value analysis. Determining the fair value of the reporting units requires management to develop significant judgments, including estimating and discounting future cash flows by reporting unit, specifically forecasted revenue, forecasted operating margins and discount rates. Intangible Assets The components of definite-lived intangible assets, net of accumulated amortization, were as follows: (Dollars in millions) 9/30/2021 12/31/2020 Developed and Acquired Technology, Net of Accumulated Amortization of $218 at September 30, 2021 and $132 at December 31, 2020 $ 371 $ 456 Trade Names, Net of Accumulated Amortization of $71 at September 30, 2021 and $41 at December 31, 2020 324 354 Intangible Assets, Net of Accumulated Amortization of $289 at September 30, 2021 and $173 at December 31, 2020 $ 695 $ 810

Interest on the Exit Notes accrues at the rate of 11.00% per annum and is payable semiannually in arrears on June 1 and December 1, which commenced on June 1, 2020. As of September 30, 2021, $200 million of the Exit Notes were classified as a current obligation. On October 20, 2021 we redeemed $200 million of our Exit Notes and paid related accrued interest of $8 million along with a bond redemption premium of $6 million. See “Note 14 – Subsequent Events” for additional details. 2024 Senior Secured Notes On August 28, 2020, we entered into an indenture and issued the 8.75% Senior Secured Notes in an aggregate principal amount of $500 million maturing September 1, 2024 (the “2024 Senior Secured Notes”). Interest accrued at the rate of 8.75% per annum and was payable semiannually in arrears on March 1 and September 1, which commenced on March 1, 2021. On September 30, 2021, we repaid our 2024 Senior Secured Notes and accrued interest with proceeds from the issuance of the 2028 Senior Secured Notes described below and cash on hand. In addition, we paid and recognized a $22 million bond redemption premium and recognized a $37 million noncash loss on extinguishment of debt related to the unamortized debt issuance costs and discount, which is presented as “Loss on Extinguishment of Debt and Bond Redemption Premium” on the Condensed Consolidated Statements of Operations. 2028 Senior Secured Notes On September 30, 2021, we entered into an indenture and issued the 6.5% Senior Secured Notes in aggregate principal amount of $500 million maturing September 15, 2028 (the “2028 Senior Secured Notes”). Interest accrues at the rate of 6.5% per annum and is payable semiannually on September 15 and March 15 of each year, commencing on March 15, 2022. The 2028 Senior Secured Notes are guaranteed by the Company and the same subsidiaries of the Company that guaranteed the 2024 Senior Secured Notes. On September 30, 2021 we received $491 million of proceeds net of debt issuance costs paid and the net book value after including accrued debt issuance costs was $488 million. Debt issuance costs will be amortized to “Interest Expense, Net” on the Condensed Consolidated Financial Statements using the effective interest rate method over the term of the debt. LC Credit Agreement We have a senior secured letter of credit agreement in an aggregate amount of $215 million maturing on May 29, 2024 (the “LC Credit Agreement”), which is used by the Company and certain of its subsidiaries for the issuance of bid and performance letters of credit. On September 20, 2021, certain provisions and covenants of the LC Credit Agreement were amended as follows: • Permit the borrowing of up to an additional $400 million of secured indebtedness under an asset-based lending facility or a revolving credit facility upon compliance with certain conditions; • Removed the minimum secured liquidity requirement; • Increased the minimum aggregate liquidity requirement from $175 million to $300 million; • Decreased the minimum aggregate book value of certain pledged assets requirement from $1.25 billion to $1 billion; and • Increased the ability to repay or redeem debt to $500 million subject to minimum aggregate liquidity of $400 million at the time of repayment or redemption. At September 30, 2021, we had approximately $173 million in outstanding letters of credit under the LC Credit Agreement and availability of $42 million. As of September 30, 2021, we had $329 million of letters of credit outstanding, consisting of the $173 million mentioned above under the LC Credit Agreement and another $156 million under various uncommitted bi-lateral facilities (for which there was $152 million in cash collateral held and recorded in “Restricted Cash” on our Condensed Consolidated Balance Sheets). Accrued Interest As of September 30, 2021 and December 31, 2020, we had accrued interest of $77 million and $34 million, respectively, in “Other Current Liabilities” on our Condensed Consolidated Balance Sheets. 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. 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 table below presents the fair value and carrying value of the Exit Notes and Senior Secured Notes. 9/30/2021 12/31/2020 (Dollars in millions) Carrying Value Fair Value Carrying Value Fair Value Exit Notes $ 2,098 $ 2,215 $ 2,098 $ 1,628 2028 Senior Secured Notes $ 488 $ 516 $ — $ — 2024 Senior Secured Notes $ — $ — $ 455 $ 507

Commitments and Contingencies Disclosure [Abstract]
Disputes, Litigation and Contingencies	Disputes, Litigation and Legal Contingencies We are subject to lawsuits and claims arising out of the nature of our business. 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 a 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 cases, the aggregate impact to our financial condition could be material. Due to the COVID-19 pandemic, many of the Company’s litigation matters and other disputes have been delayed due to court closures or other mandated accommodations. GAMCO Shareholder Litigation On September 6, 2019, GAMCO Asset Management, Inc. (“GAMCO”), purportedly on behalf of itself and other similarly situated shareholders, filed a lawsuit asserting violations of the federal securities laws against certain then-current and former officers and directors of the Company. GAMCO alleges violations of Sections 10(b) and 20(b) of the Securities Exchange Act of 1934 (as amended, the “Exchange Act”), and violations of Sections 11 and 15 of the Securities Act of 1933, as amended (the “Securities Act”) based on allegations that the Company and certain of its officers made false and/or misleading statements, and alleged non-disclosure of material facts, regarding our business, operations, prospects and performance. GAMCO seeks damages on behalf of purchasers of the Company’s ordinary shares from October 26, 2016 through May 10, 2019. GAMCO’s lawsuit was filed in the United States District Court for the Southern District of Texas, Houston Division, and it is captioned GAMCO Asset Management, Inc. v. McCollum, et al., Case No. 4:19-cv-03363. The District Court Judge appointed Utah Retirement Systems (“URS”) as Lead Plaintiff, and on March 16, 2020, URS filed its Amended Complaint. URS added the Company as a defendant but dropped the claims against non-officer board members and all the claims under the Securities Act. On May 14, 2021, the District Court dismissed the case with prejudice for failure to state a claim. On August 9, 2021, the plaintiffs filed their Notice of Appeal with the District Court. The case is still pending appeal and we cannot reliably predict the outcome of the claims, including the amount of any possible loss.

Revenue from Contract with Customer [Abstract]
Revenues	Revenues Revenue by Product Line and Geographic Region Revenues are attributable to countries based on the ultimate destination of the sale of products or performance of services. Our two product lines are as follows: (1) Completion and Production and (2) Drilling, Evaluation and Intervention. The unmanned equipment that we lease to customers under operating leases consists primarily of drilling rental tools (in the Drilling, Evaluation and Intervention product line) and artificial lift pumping equipment (in the Completion and Production product line). 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. The following tables disaggregate our product and service revenues by major product line and geographic region for the three and nine months ended September 30, 2021 and 2020 and includes equipment revenues recognized under lease accounting standards of $34 million and $97 million in the three and nine months ended September 30, 2021, respectively, and $30 million and $119 million for the three and nine months ended September 30, 2020, respectively.

Our receivables are primarily derived from contract sales of products and services, which are included in “Accounts Receivable, Net” on the Condensed Consolidated Balance Sheets. Contract assets were immaterial as of September 30, 2021 and December 31, 2020. Revenue recognized during the nine months ended September 30, 2021 that was included in the contract liabilities balance at the beginning of 2021 was $28 million. The following table summarizes these balances as of September 30, 2021 and December 31, 2020: (Dollars in millions) 9/30/2021 12/31/2020 Receivables for Product and Services in Accounts Receivable, Net $ 782 $ 792 Total Accounts Receivables $ 816 $ 826 Contract Liabilities $ 31 $ 37 Performance Obligations In the following table, estimated revenue for contracts with original performance obligations greater than twelve months are expected to be recognized in the future related to performance obligations that are either unsatisfied or partially unsatisfied as of September 30, 2021.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We determined our quarterly tax provision using the year-to-date effective tax rate because small changes in estimated ordinary annual income result in significant changes in our estimated annual effective tax rate. The year-to-date effective tax rate treats the year-to-date period as if it was the annual period and determines the income tax expense or benefit on that basis. In the three and nine months ended September 30, 2021, we recognized tax expense of $28 million and $66 million, respectively, on a loss before income taxes of $61 million and $206 million, respectively, compared to the three and nine months ended September 30, 2020 where we recognized tax expense of $8 million and $64 million, respectively, on a loss before income taxes of $159 million and $1.6 billion, respectively. Our income tax provisions are primarily driven by income in certain jurisdictions, deemed profit countries and withholding taxes on intercompany and third-party transactions that do not directly correlate to ordinary income or loss and other adjustments. Impairments and other charges recognized do not result in significant tax benefit as a result of our inability to forecast realization of the tax benefit of such losses. We routinely undergo 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. As of September 30, 2021, we anticipate that it is reasonably possible that our uncertain tax positions of $241 million may decrease by up to $13 million in the next twelve months due to expiration of statutes of limitations, settlements and/or conclusions of tax examinations.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Accounting	The accompanying unaudited Condensed Consolidated Financial Statements of Weatherford International plc (the “Company,” or “Weatherford”) have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, certain information and disclosures normally included in our annual consolidated financial statements have been condensed or omitted. Therefore, these unaudited Condensed Consolidated Financial Statements should be read in conjunction with our audited Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2020 (“2020 Annual Report”). The preparation of the Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the Condensed Consolidated Financial Statements and the reported amounts of revenue and expenses during the reporting period. Ultimate results could differ from our estimates.
Principles of Consolidation	In the opinion of management, the Condensed Consolidated Financial Statements reflect all adjustments (consisting of normal recurring adjustments) considered necessary by management to fairly state the results of operations, financial position and cash flows of Weatherford and its subsidiaries for the periods presented and are not necessarily indicative of the results that may be expected for a full year. Our financial statements have been prepared on a consolidated basis. Under this basis, our financial statements consolidate all wholly owned subsidiaries and controlled joint ventures. All intercompany accounts and transactions have been eliminated.
Reclassifications	Summary of Significant Accounting PoliciesPlease refer to “Note 1 – Summary of Significant Accounting Policies” of our Consolidated Financial Statements from our 2020 Annual Report for the discussion on our significant accounting policies.
