| Income Tax Disclosure [Abstract] | |
| Taxation | Taxation For the three and six months ended June 30, 2025, income tax expense was $29 million and $44 million, respectively, compared to income tax expense of $3 million and $13 million for the three and six months ended June 30, 2024, respectively. The increase in tax expense for the three and six months ended June 30, 2025, relative to the three and six months ended June 30, 2024, primarily reflects changes in the Company's mix of pre-tax income and loss among tax jurisdictions in addition to the recognition of a tax benefit in 2024, attributable to changes in valuation allowances established for Switzerland and Brazil. On July 4, 2025, the U.S. enacted the One Big Beautiful Bill Act ("OBBBA"). The OBBBA includes many tax provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act and provisions allowing accelerated tax deduction for qualified property. We will continue to evaluate the impact of the legislation to our unaudited Condensed Consolidated Financial Statements.

Diluted (LPS)/EPS includes the effect of the assumed conversion of potentially dilutive instruments related to the effect of the unsecured senior convertible bond and share based compensation. Refer to Note 9 – "Debt" for further details on the unsecured senior convertible bond. The components of the numerator for the calculation of basic and diluted (LPS)/EPS were as follows:
The components of the denominator for the calculation of basic and diluted (LPS)/EPS were as follows:

(1) For the three and six months ended June 30, 2025, the effect of including all potentially dilutive instruments in the calculation resulted in decreased loss per share, which is anti-dilutive. The instruments were not included in the calculation due to their anti-dilutive effect, and, as a result, the basic and diluted loss per share are equal.

| Fair Value Disclosures [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Fair value of financial instruments | Fair value of financial instruments The carrying values and estimated fair values of certain of our financial instruments as of the dates specified were as follows:
Fair value is a market-based measurement, not an entity-specific measurement, and is determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, a fair value hierarchy distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within levels 1 and 2 of the hierarchy) and the reporting entity's own assumptions about market participant assumptions (unobservable inputs classified within level 3 of the hierarchy). Financial instruments categorized as level 1 The fair value of the $575 million secured bond is based on market traded value. Financial instruments categorized as level 3 The fair value attributed to the unsecured senior convertible bond is bifurcated into two elements: the straight debt component is derived through a discounted cash flow approach, and the conversion option is derived through an option pricing model, which forecasts equity volatility and compares the potential conversion redemption against historical and implied equity movements in comparable companies in our industry. The conversion option was recorded in equity at the point the bond was issued and, therefore, has not been included in the table above. Our cash and cash equivalents, restricted cash, accounts receivable and accounts payable are by their nature short-term. As a result, the carrying values included in our unaudited Condensed Consolidated Balance Sheets approximate fair value.

Commitments and contingencies |

| Commitments and Contingencies Disclosure [Abstract] | |
| Commitments and contingencies | Commitments and contingencies We recognize loss contingencies in the unaudited Condensed Consolidated Financial Statements where it is probable that an outflow of economic benefits will be required to settle an obligation and the amount is reasonably estimable. An adverse outcome in a matter described below could have an adverse effect on Seadrill's operating results, cash flows and financial position. Accruals for contingencies related to matters described below, if any, are recorded in "Accrued expenses" within "Other current liabilities" and "Uncertain tax positions" within "Other non-current liabilities" in the unaudited Condensed Consolidated Balance Sheets. Legal Proceedings SFL Hercules Ltd On March 5, 2023, Seadrill was served with a claim from SFL Hercules Ltd., filed in the Oslo District Court in Norway, relating to our redelivery of the rig West Hercules to SFL Corporation Ltd. ("SFL") in December 2022. On February 6, 2025, the Oslo District Court delivered a judgment in favor of SFL Hercules Ltd. ordering Seadrill to pay SFL approximately $37 million plus interest and legal costs of approximately $11 million. Seadrill intends to vigorously contest the judgment and filed an appeal on March 5, 2025. The timing of resolution and ultimate amount due, if any, cannot be predicted at this time. Sonadrill fees claim In March 2023, Seadrill was served with a claim from an individual (the "Claimant") filed in the High Court of Justice, Business and Property Courts of England and Wales, King's Bench Division, Commercial Court (the "High Court"). The Claimant alleged breach of contract and unjust enrichment damages of approximately $72 million related to an alleged failure by the Company to pay the Claimant a fee for services in arranging the Sonadrill joint venture dating back to 2018. The case concluded on March 18, 2025. On July 11, 2025, the High Court rendered judgment in favor of the Claimant. The parties are continuing to make submissions to the High Court on the issue of the quantum of damages to be paid; however, Seadrill presently estimates that its liability following the High Court's judgment is unlikely to exceed $53 million, subject to finalization of calculations relating to interest. This amount is exclusive of any claim by the Claimant in respect of legal fees, a portion of which may be awarded by the High Court at a later date. During the second quarter of 2025, Seadrill has estimated an increase to the contingency accrual of $51 million, which is recognized within "Management contract expenses" in the unaudited Condensed Consolidated Statement of Operations. Seadrill is reviewing the judgment and evaluating its options, including the possibility of seeking permission for an appeal to the Court of Appeal. Nigerian Cabotage Act litigation In November 2015, the Nigerian Maritime Administration and Safety Agency ("NMASA") issued a detention in respect of the rig West Capella for failure to comply with requirements of the Coastal and Inland Shipping (Cabotage) Act 2003 (the "Cabotage Act"), specifically, failure to pay a Cabotage fee of 2% on contract revenue. While the named party is Seadrill Mobile Units Nigeria Ltd (previously an Aquadrill entity, acquired by Seadrill upon the merger of Seadrill and Aquadrill) ("SMUNL"), the matter relates to three rigs: the West Capella, West Saturn and West Jupiter. SMUNL commenced proceedings in May 2016 against the Honourable Minister for Transportation, the Attorney General of the Federation and NMASA with respect to interpretation of the Cabotage Act. On June 14, 2019, the Federal High Court of Nigeria delivered a judgment (1) finding that: (a) Drilling operations fall within the definition of "Coastal Trade" or "Cabotage" under the Cabotage Act and (b) Drilling Rigs fall within the definition of "Vessels" under the Cabotage Act, and (2) directing SMUNL to deduct 2%, or approximately $69 million, of their contract value and remit the same to NMASA. On June 24, 2019, the Court of Appeals sitting in Lagos ("COA") issued a conflicting judgment in Transocean Support Services Nigeria & Ors v NIMASA & Anor, finding drilling rigs cannot be deemed vessels under the Cabotage Act pending appeal. SMUNL filed an appeal to the COA on July 22, 2019, and applied to the Federal High Court for an injunction pending appeal to prevent enforcement. Due to the volume of cases currently being handled by the COA, the Registry of the COA is yet to schedule the hearing date for the appeal. Although we intend to strongly pursue this appeal, we cannot predict the outcome of this case. Sete Brazil claim On January 6, 2025, Seadrill Brazil received notices from Petroleo Brasileiro S.A. ("Petrobras") asserting delay penalties against Seadrill Brazil relating to drillships to be operated in Brazil by Seadrill Brazil pursuant to the Sete Brazil Project, an initiative aimed at constructing a fleet of 28 offshore drilling rigs to support Petrobras. The alleged penalties arise from contracts awarded in relation to the Sete Brazil Project in 2012 for three drillships that were to be constructed by Sete Brazil and operated by Seadrill, but were never completed. Sete Brazil was eventually declared bankrupt by the Brazilian courts in December 2024 although that bankruptcy is presently suspended. The aggregate amount claimed by Petrobras as of the date of receipt of the notices was approximately $213 million in delay penalties, with the potential for further delay penalties, which could be significant, to be assessed ratably over the remaining term of the drilling contracts for the three Sete drillships. The contracts limit aggregate delay penalties to 10% of the total "estimated contract value," as defined in the contract. Petrobras has indicated it may exercise set-off rights against certain amounts payable to Seadrill Brazil under its contracts with Petrobras for our five drillships currently operating in Brazil, revenues related to which are included in our backlog as of June 30, 2025. No set-off right has been exercised to date. Petrobras and Seadrill have agreed to participate in voluntary mediation, and Petrobras has committed to not exercise any set-off rights pending the outcome of the mediation. While Petrobras has indicated that the mediation could commence in the third quarter of 2025, no date has been set. We cannot predict when the mediation will be completed, or what the outcome may be. Dialogue between the parties is ongoing. We are evaluating our legal options, which may include, among other things, seeking injunctive relief and asserting counterclaims against Petrobras in Brazilian courts, and seeking remedies against Petrobras under Seadrill’s prior U.S. Chapter 11 bankruptcy proceedings. This matter is in its early stages, and we are not able to predict its timing or outcome. In addition, the nature, timing, calculation and ultimate amount of the purported penalties are subject to principles of contract interpretation before Brazilian courts. Seadrill intends to vigorously defend its position and pursue available remedies. Brazil tax audit Seadrill Serviços de Petróleo Ltda ("Seadrill Brazil") has a long-standing tax audit relating to years 2009 and 2010, which is being litigated through the Brazilian courts. The initial court ruled in favor of Seadrill Brazil, but the appellate court reversed the lower court decision in September 2023 and ruled in favor of the tax authorities, assessing a tax and interest thereon of approximately $75 million. We will vigorously defend our position and, in the first quarter of 2024, our appeal was admitted by the higher courts, but the ultimate timing and outcome of this litigation cannot be determined. There are additional open cases relating to years 2012, 2016, and 2017, where a similar principle is being contested but they are not as far advanced through the courts, for an aggregate assessed amount, including tax and interest, of approximately $80 million. In order to litigate the tax audit relating to years 2009 and 2010, Seadrill Brazil has entered into an agreement for an insurance bond of BRL413 million ($75 million as of June 30, 2025). Other matters In addition to the foregoing, from time to time we are a named defendant or party in certain other lawsuits, claims or proceedings arising in the ordinary course of business or in connection with our acquisition and disposal activities. Although the outcome of such lawsuits or other proceedings cannot be predicted with certainty, and the amount of any liability that could arise with respect to such lawsuits or other proceedings cannot be predicted accurately, we currently do not expect these other matters to have a material adverse effect on our financial position, operating results and cash flows. Guarantees We have issued performance guarantees for potential liabilities that may result from drilling activities under current or previously managed rig arrangements with Sonadrill. As of June 30, 2025, we have not recognized any liabilities for these guarantees as we do not consider it probable that the guarantees will be called. The guarantees provided on behalf of Sonadrill have been capped at $1.1 billion (December 31, 2024: $1.1 billion), in the aggregate, across the three rigs we manage for the joint venture on two active, and two historic, contracts.
