The Sakhalin Papers C: The Hundredth File — How Russia Twice Changed the Rules of Shell’s Biggest Energy Gamble
A documentary investigation into the Kremlin’s interventions of 2006 and 2022, the environmental and financial disputes, the surviving Shell records, and the consequences that remain unresolved.
AN INDEPENDENT DOCUMENTARY INVESTIGATION
By the Donovan–Shell Archive
Researched and drafted with assistance from ChatGPT, using authenticated Shell corporate disclosures, SEC filings, contemporaneous reporting, Russian regulatory records, independently published environmental research, court proceedings and historical material preserved in the Donovan–Shell Archive.

Previous instalment: SLF-2007-109 — The Shareholding That Survived, 5 November 2026
One hundred Sakhalin investigations have brought us to an extraordinary comparison. In December 2006, Shell surrendered majority ownership of Sakhalin II to Gazprom following months of environmental investigations, disputed construction costs and intense political pressure. Sixteen years later, Russia intervened again, this time establishing a new operating company under presidential decree after Shell announced its withdrawal following the invasion of Ukraine. The first intervention preserved Shell as a substantial shareholder and technical participant. The second ended that participation and left Shell’s former investment entangled in contested compensation arrangements and Russian litigation. The surviving documents establish the mechanisms of both interventions. They also identify the limits of what can responsibly be concluded about their motives, legality and long-term consequences.
Introduction: The hundredth file
The hundredth investigation in The Sakhalin Papers provides an opportunity to examine the larger historical record.
For months, this series has followed the development of Sakhalin II through confidential correspondence, technical warnings, environmental disputes, Kremlin negotiations, corporate disclosures, regulatory intervention and legal proceedings.
Some documents have been relatively obscure.
Others have been publicly available for years but rarely examined together.
Among them are original Shell internal emails, correspondence preserved by the Donovan–Shell Archive, official financial filings, contemporary news reports and documents recording decisions by governments and financial institutions.
The archive has also examined anonymous whistleblower allegations.
Those allegations have not automatically been accepted as fact.
Where subsequent events corroborated a prediction, that has been recorded.
Where an accusation remained unsupported, it has been identified as unproven.
This distinction has been essential because Sakhalin II has attracted competing historical interpretations.
One presents the project as an example of foreign energy companies encountering the consequences of their own environmental and financial mismanagement.
Another presents it as an example of the Russian state using regulatory power to strengthen its control over strategic natural resources.
There is documentary evidence relevant to both interpretations.
But neither, taken alone, adequately explains the entire history.
The most revealing evidence emerges when the two major interventions are examined side by side.
In 2006, Russia changed who controlled the original operating company. In 2022, Russia changed which company operated the project.
Those were fundamentally different transactions.
Their consequences continue to appear in Shell’s financial disclosures almost twenty years after the first intervention.
PART ONE: THE FIRST INTERVENTION
1. The 1994 agreement that made everything possible
The Sakhalin II project was developed under a production-sharing agreement concluded on 22 June 1994.
The project involved the Piltun-Astokhskoye oil field and the Lunskoye gas field, offshore Sakhalin Island.
Sakhalin Energy Investment Company Ltd was established as the operating vehicle.
The company’s original ownership structure eventually comprised Royal Dutch Shell with 55%, Mitsui with 25% and Mitsubishi with 20%.
The project required a substantial industrial infrastructure programme.
Offshore platforms would produce hydrocarbons.
Pipelines would transport oil and gas across Sakhalin Island.
A processing and liquefaction complex would produce LNG for international customers.
Export facilities would connect the development to markets in Japan, South Korea and elsewhere.
These were long-term investments requiring substantial capital.
The production-sharing agreement was central to the commercial arrangements.
Under its contractual framework, allowable development costs could be recovered from project production before the Russian state received the full economic benefits expected under the agreed cost-recovery and profit-sharing arrangements.
This created a particular sensitivity to construction expenditure.
If recoverable project costs increased substantially, the timing and amount of revenues available to the state could be affected.
The agreement therefore linked commercial performance to the interests of the Russian government.
This was not an incidental feature.
It became central to the confrontation that followed.
The full contractual provisions governing every later dispute have not been independently established in this investigation. The description above reflects the production-sharing structure documented in the companies’ regulatory filings and contemporaneous reporting.

2. Gazprom was already negotiating before the environmental crisis
An important documentary correction is necessary.
Gazprom did not first become interested in Sakhalin II during the environmental confrontation of autumn 2006.
Shell and Gazprom were negotiating an arrangement well before that crisis reached its peak.
On 7 July 2005, the companies announced a proposed asset exchange.
Gazprom would acquire approximately 25% plus one share in Sakhalin Energy.
Shell would obtain a 50% interest in a venture associated with Gazprom’s Zapolyarnoye gas field in western Siberia.
The precise balancing consideration would be determined through subsequent negotiations.
The arrangement offered potential benefits to both companies.
Gazprom would obtain participation in a major LNG project.
Shell would gain an interest in another substantial Russian gas resource.
At that stage, the contemplated Gazprom participation was a minority position.
It was not majority control.
This distinction matters when assessing the later events.
The original negotiations were not invented by regulators as part of the environmental investigation.
But the final transaction was substantially different from the earlier proposal.
By December 2006, Gazprom was no longer negotiating merely to become a minority participant.
It was acquiring control.

3. The construction budget became a political problem
By 2005 and 2006, Sakhalin II was experiencing major construction-cost escalation.
The project’s estimated second-phase development expenditure had risen dramatically.
Contemporaneous reporting described estimates approaching $20 billion for Phase 2 and approximately $22 billion for the wider development.
Russian officials challenged the increased expenditure.
Their concern was understandable in economic terms.
Under the production-sharing arrangements, the treatment of recoverable expenditure affected the state’s financial return.
The Russian government was therefore not merely commenting on a company’s private construction budget.
It was examining expenditure with consequences for its own contractual revenue.
In October and November 2006, contemporaneous Reuters reporting described Russian reviews of the project’s costs, including scrutiny by the state-owned company Zarubezhneft.
Some officials alleged that the figures had been overstated.
Those assertions were part of a contested financial assessment.
They should not be represented as independently established evidence of fraud or deliberate cost inflation by Shell.
The record demonstrates that the development budget was disputed.
It does not establish that every item questioned by the Russian authorities was improperly incurred.
Nor does it establish that Shell deliberately misrepresented the project’s total cost.
The distinction between a cost overrun and financial misconduct is fundamental.
A project may become substantially more expensive because of engineering complexity, inflation, contractor performance, design changes or management failures.
Determining which explanations apply requires examination of the underlying cost records.
The contemporaneous reports demonstrate that Russia’s dissatisfaction was real.
They do not settle every disputed financial question.

4. Environmental concerns were genuine — but their political use remains contested
The environmental controversy cannot responsibly be dismissed as wholly fabricated.
Sakhalin II involved major construction activity in a sensitive natural environment.
The project raised concerns about river crossings, sedimentation, fisheries, habitat disturbance and the critically endangered western gray whale.
These concerns existed independently of the Kremlin’s eventual acquisition negotiations.
In 2005, an independent scientific review panel convened under the auspices of the International Union for Conservation of Nature examined the project’s potential effects on western North Pacific gray whales.
The panel considered risks associated with construction and operation, mitigation measures and the need for monitoring.
Its report was published before the decisive 2006 ownership transfer.
That chronology is important.
It demonstrates that concerns about the project were not simply invented after relations between Shell and Russian regulators deteriorated.
Environmental organisations, independent scientists and local communities had already been examining Sakhalin II.
Shell’s own 2006 Sustainability Report subsequently acknowledged environmental-management difficulties, including construction-related problems requiring stronger controls.
Those admissions should form part of any balanced historical assessment.
However, the existence of genuine environmental problems does not establish that every enforcement measure adopted by Russian authorities was proportionate or free from political influence.
In September 2006, Russia’s Natural Resources Ministry cancelled a key environmental approval associated with the project.
The action followed escalating disputes over compliance.
Russian officials defended the intervention as necessary environmental enforcement.
Shell and Sakhalin Energy disputed aspects of the allegations and their severity.
Contemporaneous analysts also questioned whether regulatory pressure was being used to improve Gazprom’s negotiating position.
These were competing positions.
The surviving record establishes the environmental concerns, the regulatory action and the contemporaneous suspicions.
It does not establish a definitive judicial finding that the Russian authorities fabricated the environmental case to compel a transfer of ownership.

5. The Kremlin meeting that changed the ownership
The decisive political and commercial meeting took place on 21 December 2006.
Representatives of Shell, Mitsui, Mitsubishi and Gazprom met at the Kremlin.
President Vladimir Putin attended.
The companies announced a protocol providing for Gazprom to acquire 50% plus one share in Sakhalin Energy.
The agreed consideration was:
US$7.45 billion.
The existing shareholders would each reduce their holdings by approximately half.
Shell’s ownership would fall from 55% to 27.5% minus one share.
Mitsui’s interest would become 12.5%.
Mitsubishi’s interest would become 10%.
Gazprom would acquire the majority position.
But the original operating company would remain in place.
Shell would also continue contributing to management and remain technical adviser.
The transaction therefore involved a substantial change in ownership rather than the creation of a replacement operating company.
This distinction is confirmed by the original corporate announcement preserved in Mitsui’s SEC filing dated 22 December 2006.
That document provides authenticated evidence of the agreed terms.
It also states that the existing LNG sales contracts would remain in force.
The commercial structure was therefore designed to preserve the project while changing its controlling shareholder.
The result was a major reduction in Shell’s ownership and control.
But Shell was not expelled from the project.

6. The environmental dispute and ownership agreement converged
The timing of the December 2006 announcement generated substantial controversy.
Russian environmental authorities had spent months investigating Sakhalin II.
The project had faced threats concerning permits and licences.
The development budget remained disputed.
Then Gazprom obtained agreement to acquire majority ownership.
Contemporaneous reporting recorded that Putin regarded fundamental environmental issues as substantially resolved following the agreement.
The significance of that sequence should neither be exaggerated nor ignored.
One possible interpretation is that the entry of Gazprom, together with revised environmental commitments and negotiations over expenditure, made a practical resolution possible.
Another is that Russian regulatory pressure strengthened Gazprom’s negotiating position and enabled it to obtain a larger interest than originally contemplated.
Both interpretations were relevant to contemporary discussion.
The second was not merely invented years later.
Journalists and financial analysts were raising the issue before the December agreement was completed.
But a chronological association is not, by itself, proof of an unlawful bargain.
No authenticated document examined here records an explicit agreement that environmental enforcement would cease in exchange for Gazprom acquiring majority control.
Nor has a judgment been identified establishing that Shell’s agreement to transfer shares was legally invalid because of coercion.
What the documentary record demonstrates is that the ownership negotiations, environmental controversy and financial disputes were resolved through overlapping political and commercial processes.

7. April 2007: A commercial transaction completed the transfer
The December protocol was implemented through a formal share-sale agreement signed on 18 April 2007.
Shell’s original announcement was filed with the United States Securities and Exchange Commission.
The filing confirms Gazprom’s acquisition of 50% plus one share for $7.45 billion.
It also confirms the resulting ownership structure.
But the announcement contains an additional detail of particular historical importance.
Shell reported that the Russian Ministry of Natural Resources had approved the project’s revised Environmental Action Plan.
That approval was recorded in the same corporate announcement as the implementation of Gazprom’s entry.
Malcolm Brinded, Shell’s Executive Director of Exploration and Production, welcomed both developments.
The contemporaneous statement therefore establishes that environmental arrangements and ownership restructuring were being presented together as progress towards completing the project.
It does not establish that the environmental problems had never existed.
It also does not establish that every environmental obligation had been fully satisfied.
The approved action plan involved commitments to future management and mitigation measures.
The distinction matters.
Regulatory approval of a plan is not identical to certification that all associated environmental impacts have disappeared.
Nevertheless, the document is revealing.
The project had moved from a confrontation involving threatened permissions to an arrangement under which Gazprom controlled the company and Russian officials accepted a revised programme of environmental action.
The political and commercial uncertainty had substantially diminished.

PART TWO: THE PROJECT THAT SURVIVED
8. Gazprom took control, but construction continued
The 2006 agreement did not end Sakhalin II.
Construction continued under the revised ownership arrangements.
The development subsequently entered production.
On 18 February 2009, Russian President Dmitry Medvedev inaugurated the LNG plant at Prigorodnoye.
The facility had a stated design capacity of approximately 9.6 million tonnes of LNG annually.
On 29 March 2009, the project dispatched its first LNG cargo to Japan.
The development was therefore operationally successful in the important sense that the infrastructure was completed and began supplying customers.
That conclusion does not settle every earlier environmental controversy.
Nor does it establish that the development was completed within its original timetable or budget.
The commencement of production is a measurable outcome.
Questions concerning cost, environmental performance and corporate accountability require separate evidence.
The fact that LNG exports began in 2009 also demonstrates something about the 2006 restructuring.
Gazprom’s acquisition did not require the original project to be abandoned.
The operating company continued.
Its international shareholders remained.
Its long-term customer relationships were preserved.
Shell still possessed a substantial minority investment.
That arrangement survived for approximately fifteen years.

9. The years between the interventions matter
The period between 2007 and 2022 should not be treated as an empty interval.
Shell remained commercially involved in the project.
Its interest was accounted for as an investment in an associate.
The company participated in management and contributed technical expertise.
Its continuing investment formed part of the wider LNG business that Shell was developing internationally.
This history is important because the second intervention did not occur immediately after a failed development.
It occurred after Sakhalin II had become an established international LNG supplier.
The project had completed its principal construction programme.
Its production infrastructure was operating.
Long-term customer relationships had developed.
The shareholders had spent years working under the post-2006 arrangements.
Consequently, the events of 2022 were not simply a continuation of an unfinished construction dispute.
They arose in a substantially different political and commercial environment.
Russia’s invasion of Ukraine transformed the position of Western energy companies operating in Russia.
Shell’s response to that invasion initiated the second major change in its Sakhalin involvement.
PART THREE: THE SECOND INTERVENTION
10. February 2022: Shell announces withdrawal
On 24 February 2022, Russia launched its full-scale invasion of Ukraine.
Four days later, Shell announced its intention to withdraw from equity partnerships with Gazprom and related entities.
The announcement specifically identified Sakhalin II.
It also referred to other Russian investments and the Nord Stream 2 project.
On 8 March, Shell broadened its decision to encompass its involvement in Russian hydrocarbons generally.
The company said the withdrawal would proceed in stages.
That qualification was important.
Shell’s announcement established its intended policy.
It did not itself transfer every shareholding, terminate every agreement or extinguish every commercial obligation.
Shell subsequently withdrew its executive directors and managerial and technical personnel from Sakhalin Energy.
Its accounting records confirm that it lost significant influence over the investment from 1 April 2022.
In its first-quarter financial results, Shell recognised an impairment of $1.614 billion relating to Sakhalin II.
The company subsequently reclassified its remaining interest as a financial asset rather than an associate.
These were substantial changes.
But they did not involve a conventional sale of Shell’s shares to another investor.
Shell had stopped participating in the project’s management before Russia established the replacement operating company.
That sequence is essential to understanding the later dispute.

11. June 2022: Russia changes the operator
On 30 June 2022, President Putin signed Presidential Decree No. 416.
The decree established a fundamentally different mechanism from the negotiated share transaction of 2006.
It provided for the creation of a new Russian limited liability company.
That company would assume the operating rights and obligations associated with Sakhalin II under the Russian measures.
The decree also set out arrangements concerning the project’s assets.
Existing foreign shareholders could apply to receive corresponding interests in the new company.
Russian authorities would decide whether to approve those applications.
Interests not transferred to the original foreign shareholders could be valued and sold under procedures established by the Russian government.
The decree also provided for sale proceeds to be placed in restricted Type-C accounts and established procedures concerning potential claims for damages.
These were not ordinary provisions in a voluntary commercial share-sale agreement.
They were measures imposed through a Russian presidential decree.
The Russian authorities justified the intervention by reference to national interests, economic security, sanctions and alleged failures associated with the production-sharing arrangements.
Those were the Russian government’s stated grounds.
Their inclusion in the decree does not independently establish that Shell breached the agreement or that every measure taken was valid under all potentially applicable laws.
The decree is authoritative evidence of what Russia ordered.
It is not a judicial determination establishing Shell’s liability.

12. The Japanese shareholders made a different decision
The responses of Mitsui and Mitsubishi provide particularly useful independent evidence.
Both companies had participated in Sakhalin II throughout its development.
Both were shareholders before Gazprom entered the project.
Both remained after the 2006 restructuring.
But unlike Shell, both subsequently sought participation in the replacement Russian operating company.
Mitsui announced on 31 August 2022 that it had submitted its consent on 25 August and had received Russian government approval on 30 August.
Mitsubishi announced on 1 September 2022 that its application had also been approved.
The Japanese companies referred to energy-supply considerations, sanctions compliance and the need to assess risks.
Their decisions illustrate how different shareholders responded to the same Russian restructuring.
Shell had decided to withdraw from Russian hydrocarbons.
Mitsui and Mitsubishi sought to preserve their participation.
The difference does not establish that one commercial decision was necessarily correct and the other incorrect.
The companies had different portfolios, shareholders, supply relationships and strategic interests.
Japan’s reliance on imported LNG was also a significant consideration.
But the contrast is important.
It demonstrates that Russia’s decree did not produce identical outcomes for all the original foreign shareholders.
For Shell, the restructuring effectively completed the loss of operational involvement.
For the Japanese shareholders, participation in the replacement company offered a route towards continuing the project.

13. The distinction between the original and replacement companies
This is one of the most important findings to emerge from the hundred investigations.
The company whose shares Gazprom acquired in 2006 was Sakhalin Energy Investment Company Ltd, registered in Bermuda.
The company established under Russia’s 2022 measures was a separate Russian legal entity.
The distinction is more than a corporate technicality.
In 2006, Gazprom acquired shares in the existing company.
The original operating entity remained intact.
In 2022, Russia imposed arrangements transferring the project’s operating rights and obligations to a different company.
Shell did not obtain a replacement interest.
Its original shares did not simply become shares in the new Russian company.
That distinction subsequently became visible in Shell’s financial statements.
The 2023 Form 20-F recorded that the original Sakhalin Energy Investment Company interest had a carrying value of zero at the end of both 2022 and 2023.
However, Shell continued to report ownership of the original shares.
The company’s 2025 Form 20-F, filed with the SEC on 12 March 2026, confirms that it still held 27.5% minus one share in the Bermuda entity.
Shell also stated that the original company purportedly no longer possessed the licences, rights and obligations associated with Sakhalin II.
This was examined in detail in the previous instalment.
For the hundredth file, the significance is historical.
In 2006, Shell lost majority control but retained an interest in an operating company. In 2022, it retained an interest in the original company after the project had been transferred to a new operator under Russian measures.
The nominal shareholding percentage survived both interventions.
The underlying commercial position did not.

PART FOUR: THE UNRESOLVED CONSEQUENCES
14. Compensation did not bring the matter to an end
Russia subsequently arranged for the disposal of the unclaimed interest corresponding to Shell’s former Sakhalin position.
The Russian authorities established a valuation of 94.8 billion roubles.
Novatek was initially approved as a prospective purchaser.
That arrangement was subsequently replaced by a sale to a Gazprom-controlled entity.
But the existence of an assessed purchase price did not establish that Shell had received unrestricted compensation.
The Russian system provided for restricted accounts and procedures concerning possible claims.
The treatment of the proceeds subsequently became entangled with a separate contractual dispute involving Gazprom Export and Shell Energy Europe.
This was not part of the original 2006 share-sale transaction.
The earlier transaction involved a negotiated cash consideration paid for shares.
The later arrangements involved a state-directed disposal process and restrictions over the use of the associated funds.
The difference is fundamental.
It illustrates how corporate ownership rights can be affected when a host state changes the legal framework governing an investment.
But whether a particular right has been unlawfully infringed, or whether compensation is legally inadequate, requires examination under the applicable laws and any available dispute-resolution mechanisms.
Those questions cannot responsibly be settled merely by describing the outcome as confiscation or expropriation.

15. The Russian litigation extends the dispute into another decade
On 2 October 2024, the Russian Prosecutor General filed proceedings in Moscow against eight Shell-group entities.
The case concerns allegations arising from Shell’s withdrawal and a separate gas-payment dispute.
Shell’s 2025 Form 20-F identifies the principal relief sought.
The prosecutor seeks declarations that Shell unlawfully abandoned support for Sakhalin Energy Investment Company.
It also seeks approximately €1.5 billion from Shell Energy Europe Limited concerning allegedly unpaid gas deliveries during 2022.
A further claim seeks permission for Gazprom Export to use approximately 94 billion roubles purportedly reserved as Sakhalin compensation to offset part of the alleged debt.
The commercial relationships are different.
The Sakhalin compensation concerns Shell’s former position in the LNG development.
The alleged gas debt concerns Shell Energy Europe’s separate dealings with Gazprom Export.
The Russian proceedings seek to connect them.
Shell’s financial disclosure states that the proceedings remain ongoing.
The company also reports that it cannot reliably estimate the amount or timing of any possible obligation or payment, or whether payment will ultimately be due.
The publicly available information does not establish that Shell owes the claimed amount.
Nor does it establish that Gazprom Export is entitled to the compensation proceeds.
No publicly verified final judgment resolving those claims has been identified for this investigation.
The archive therefore records the litigation as contested.

PART FIVE: WHAT THE FIRST HUNDRED FILES PROVE
16. The authenticated internal correspondence matters — but it has limits
The Donovan–Shell Archive contains material that adds another dimension to the public record.
Among the documents examined earlier in this series are Shell-linked technical emails from 2002, correspondence involving the Donovan operation and Russian regulator Oleg Mitvol, and later internal Shell communications concerning media interest in the leaked material.
The August 2026 investigations reconstructed how technical correspondence reached the Donovan websites and was subsequently brought to Mitvol’s attention.
An authenticated Shell internal email from February 2007 recorded that the company’s media department was dealing with national newspaper interest in the leaked Sakhalin material.
The archive has also examined the authenticated April 2007 motivational email written by Sakhalin Energy Deputy Chief Executive David Greer.
That document demonstrated significant managerial concern about the project’s schedule and the confidence of personnel involved in pipeline construction.
These records are historically valuable because they preserve aspects of the controversy that were not originally intended for general publication.
But their evidential boundaries must remain clear.
The technical emails establish that concerns were expressed.
They do not automatically establish that every concern was technically correct.
The correspondence involving Mitvol establishes that information reached a Russian regulator.
It does not prove that the information caused the December 2006 ownership transfer.
The Greer email establishes that a senior executive expressed concern about the project organisation.
It does not prove that every accusation subsequently made by anonymous sources was correct.
Nor does the existence of internal Shell discussions concerning publicity establish that every allegation made by the Donovan websites was true.
The archive’s historical importance rests partly on its ability to preserve these distinctions.
An internal corporate document can be authentic while the interpretation placed upon it remains contested.

17. The court records establish narrower conclusions than some campaign claims
The Sakhalin controversy generated legal proceedings beyond Russia.
An important example concerns the British Export Credits Guarantee Department.
Environmental organisations sought access to government information connected with proposed support for Sakhalin II.
In August 2007, an Information Tribunal ruled in favour of disclosure.
The department appealed.
The matter reached the High Court as:
Export Credits Guarantee Department v Friends of the Earth [2008] EWHC 638 (Admin).
Mr Justice Mitting dismissed the appeal.
The judgment upheld the Information Tribunal’s disclosure decision.
That was an important result for transparency.
But it was not a judicial finding that Shell had committed environmental offences.
Nor was it a judgment declaring the Sakhalin II production-sharing agreement unlawful.
The case concerned access to environmental information and the application of the relevant disclosure rules.
A separate judicial-review challenge concerning the department’s proposed financial support did not proceed to a substantive determination after Sakhalin Energy withdrew its application.
Those legal distinctions matter.
A court judgment concerning disclosure must not be transformed into a finding of corporate environmental liability.
Likewise, a legal challenge that ends without a merits determination cannot be presented as though the claimant’s allegations were judicially established.
The documentary record is strong enough without making those errors.

THE DOCUMENTARY VERDICT
18. What can be established with confidence?
After one hundred investigations, several conclusions rest upon authenticated documentary evidence.
The 2006 ownership transaction was real and contractually documented. Gazprom acquired 50% plus one share in Sakhalin Energy for $7.45 billion under agreements announced in December 2006 and implemented in April 2007.
Environmental concerns existed independently of Russia’s acquisition negotiations. Independent scientific assessment, environmental-group reporting and Shell’s own disclosures establish that the project faced genuine environmental-management challenges.
Russian regulatory pressure intensified during the ownership negotiations. Environmental permits, development costs and the project’s future were being disputed while Gazprom sought a larger stake.
The final Gazprom transaction was substantially different from the earlier 2005 proposal. A prospective minority investment became majority control.
The original Sakhalin operating company survived the 2006 transaction. Shell remained a substantial shareholder and continued contributing technical expertise.
The project subsequently became operational. Russia’s first LNG plant began production in 2009 and delivered LNG to international customers.
Shell announced its intention to withdraw from Russia in 2022. Its directors and technical personnel were withdrawn from Sakhalin Energy, and the company reported losing significant influence from April 2022.
Russia’s June 2022 decree established a replacement operating structure. Shell declined to participate, while Mitsui and Mitsubishi sought interests in the new Russian company.
Shell’s original shareholding continued to appear in its later financial disclosures. That ownership interest did not establish continuing operational participation or economic value.
The financial consequences remained unresolved in Shell’s latest detailed annual disclosure. Its 2025 Form 20-F described continuing Russian litigation and uncertainty concerning possible obligations.
These conclusions can be supported by original corporate announcements, SEC filings, legal documents and contemporaneous reporting.
They do not require speculation about undisclosed conversations or motives.
19. What remains allegation, inference or unresolved legal question?
A number of more controversial propositions cannot be established to the same standard.
The record does not prove that every Russian environmental allegation made in 2006 was fabricated.
Nor does it prove that environmental enforcement was entirely free from political or commercial considerations.
It does not establish an explicit written bargain requiring Shell to surrender majority control in exchange for regulators abandoning their objections.
The surviving internal correspondence does not prove that the Donovan operation caused Gazprom to acquire control of Sakhalin II.
It does not establish that every anonymous whistleblower allegation concerning the project’s construction was correct.
Nor does it establish that the Russian decree of June 2022 was valid, or invalid, under every potentially applicable international legal principle.
Those are separate questions.
Some require access to documents that are not publicly available.
Others would require findings by courts or arbitral tribunals with jurisdiction to determine the relevant disputes.
The Russian prosecutor’s allegations against Shell remain allegations.
The continuing ownership of the original Bermuda company does not establish that Shell possesses an enforceable right to recover the operating project.
And the existence of a restricted compensation account does not establish that Shell can freely obtain or use the money associated with it.
These limitations are not weaknesses to be concealed.
They define the boundary between historical reconstruction and unsupported certainty.
EDITORIAL COMMENTARY
20. The two interventions reveal a larger problem for international investors
There is an important historical pattern in the Sakhalin record.
In both 2006 and 2022, Russia exercised substantial power over the legal and commercial circumstances of an internationally owned energy development.
But the methods differed.
In 2006, the immediate outcome was achieved through negotiated corporate agreements.
Shell and its partners transferred shares to Gazprom for cash.
The original project company remained.
In 2022, the operating structure was changed by presidential decree.
Shell did not agree to participate in the replacement company.
The project continued operating under the new Russian arrangements.
The contrast demonstrates the importance of distinguishing a host state’s regulatory authority from its power to restructure commercial relationships.
Governments have legitimate interests in environmental protection, taxation, economic security and the regulation of strategic industries.
Companies operating internationally must comply with applicable laws.
But investors also depend upon contractual stability and the enforceability of rights.
A production-sharing agreement is intended to establish a framework for allocating those rights and obligations.
The difficulty arises when parties disagree about how the framework should operate and when the state itself possesses the authority to change important aspects of the operating environment.
Sakhalin II became an unusually visible example of that problem.
The first intervention changed the balance of shareholder power.
The second changed the operating company’s legal structure.
The consequences for Shell were different, but both episodes demonstrated the vulnerability of large international investments to political developments.
21. The environmental evidence should not be sacrificed to a geopolitical argument
The 2006 controversy provides a warning against simplifying history.
It would be inaccurate to suggest that environmental organisations and independent scientists had no legitimate concerns about Sakhalin II.
The IUCN’s work demonstrates otherwise.
The project was being developed in an environmentally sensitive region.
Its construction involved risks requiring careful assessment and management.
Shell had responsibilities associated with those risks.
But recognising that does not require accepting every Russian regulatory allegation as correct.
Nor does it require assuming that environmental enforcement was unrelated to the Kremlin’s wider energy strategy.
Both questions deserve separate examination.
Environmental evidence should be judged according to its scientific and technical merits.
Regulatory decisions should be assessed against the applicable legal framework.
Corporate transactions should be examined through their documented terms.
And allegations about political motives should be supported by evidence rather than simply inferred from the eventual outcome.
The Sakhalin record is sufficiently complex to require all four approaches.
22. The Japanese experience complicates the idea of a single inevitable outcome
The different responses of Shell, Mitsui and Mitsubishi in 2022 also deserve attention.
Shell withdrew.
The Japanese shareholders sought continued participation.
Russia approved their applications.
The distinction demonstrates that the consequences of the decree were affected by each shareholder’s choices and circumstances.
Shell’s withdrawal followed its stated policy concerning Russia’s invasion of Ukraine.
The Japanese companies gave considerable weight to energy security and continuing supply.
Their choices do not establish that Russia treated every foreign shareholder identically.
Nor do they prove that any company possessed an uncomplicated route through the legal and sanctions issues.
What they demonstrate is that the same political event can produce different corporate decisions.
The economic consequences depend upon commercial relationships, national energy needs, shareholder obligations and the surrounding legal restrictions.
This makes Sakhalin II more than a history of Shell alone.
It is also a case study in the difficult choices facing international companies when geopolitics threatens long-established energy investments.
23. What Shell shareholders should take from the record
Shell shareholders have a particular interest in understanding the distinction between legal ownership and economic control.
In 2006, Shell sold a substantial part of its investment but remained in a commercially active enterprise.
In 2022, it withdrew from the enterprise’s management and subsequently lost participation in the replacement operator.
Yet the original shareholding continued to appear in its financial disclosures.
This is not necessarily contradictory.
The legal ownership of shares, their recognised accounting value, the rights held by the issuing company and the ability to recover economic benefits are separate matters.
Those distinctions became especially important after Russia’s restructuring.
The later litigation added another layer of uncertainty.
The publicly disclosed compensation arrangements became connected to claims concerning a different gas-supply relationship.
A dispute that began as a question of ownership consequently became intertwined with contractual liabilities, restricted funds and the interpretation of measures introduced during the conflict in Ukraine.
For shareholders, the relevant questions are therefore not limited to how much money Shell originally invested or received.
They include the nature of the rights that survived, the enforceability of those rights and the possible consequences of continuing legal proceedings.
The authenticated financial statements provide important information.
They do not answer every remaining question.
CONCLUSION: ONE HUNDRED FILES, TWO KREMLIN INTERVENTIONS, ONE UNFINISHED STORY
The hundredth Sakhalin investigation brings together events separated by sixteen years but connected through the same operating project.
On 21 December 2006, Shell and its Japanese partners agreed to transfer majority ownership of Sakhalin Energy to Gazprom.
The agreement followed a period of intense environmental, financial and political controversy.
The original company survived.
Shell remained a substantial shareholder.
The project continued.
By 2009, Sakhalin II was delivering LNG to international customers.
Then came February 2022.
Russia invaded Ukraine.
Shell announced its intention to withdraw from Russian hydrocarbons.
Its management and technical participation in Sakhalin Energy ended.
Russia subsequently established a new operating company through Presidential Decree No. 416.
Shell declined to participate.
Its interest in the original Bermuda company remained recorded, but the project had moved into a different legal structure.
The compensation arrangements became disputed.
Separate gas-payment claims entered the litigation.
And Shell’s 2025 financial disclosures still described unresolved legal proceedings.
The contrast is striking.
In 2006, Shell lost control but retained participation.
In 2022, Shell ended participation and lost its connection to the operating project.
In both cases, the underlying development continued.
The industrial infrastructure remained valuable.
The LNG facilities continued to serve international markets.
But the legal and commercial position of one of the project’s original investors changed fundamentally.
The documentary record does not support reducing the entire history to an uncomplicated story of corporate victimhood.
Shell’s environmental responsibilities and the project’s development difficulties were real.
Nor does the record justify treating every Russian intervention as an ordinary regulatory decision detached from wider political and commercial interests.
The circumstances were more complicated.
The central lesson is that international investment depends upon more than ownership percentages and contractual promises.
It depends upon the ability of those arrangements to withstand profound changes in political circumstances.
Sakhalin II demonstrates how difficult that can become.
And the continuing Russian litigation shows that the legal consequences of withdrawal can persist long after a company has ceased participating in the underlying business.
After one hundred investigations, the most important conclusion may be that Sakhalin II was not simply a project Shell lost. It was a project whose legal, commercial and political foundations were transformed twice — and whose consequences for Shell have still not been fully resolved.
The archive has preserved the evidence of those transformations.
Its task now is to continue examining the questions the evidence leaves unanswered.

DOCUMENTARY DISCLAIMER
This investigation examines two major interventions affecting Shell’s investment in Sakhalin II: the negotiated Gazprom acquisition announced in December 2006 and implemented in April 2007, and the replacement operating arrangements established under Russian Presidential Decree No. 416 of June 2022.
The account is based upon authenticated corporate announcements, SEC filings, Russian legal records, independently published scientific assessments, contemporaneous reporting, relevant British court proceedings and historical material preserved in the Donovan–Shell Archive.
The 2006 environmental concerns are not dismissed as fabricated.
The report distinguishes independently documented environmental problems from particular allegations made by Russian regulators.
It also distinguishes the existence of regulatory pressure from legal proof that the December 2006 share transaction was obtained through unlawful coercion.
No definitive judicial finding establishing such coercion is relied upon.
The earlier proposed Gazprom minority investment is distinguished from the eventual acquisition of majority control.
The 2006 commercial share-sale agreements are distinguished from Russia’s 2022 state-directed restructuring.
The original Bermuda-registered Sakhalin Energy Investment Company Ltd is distinguished from the replacement Russian company.
Shell’s continuing ownership of shares in the original company is not represented as evidence of continuing operational control or recoverable economic value.
Russian governmental assertions concerning the justification for the 2022 decree are identified as governmental positions.
Their inclusion in the decree is not treated as an independent finding that Shell breached the production-sharing agreement.
The report makes no definitive conclusion concerning the validity of the 2022 measures under international law or any applicable investment treaty.
Russian prosecutorial allegations are identified as contested claims.
No publicly verified final judgment resolving those claims has been identified.
The investigation does not establish that Shell owes Gazprom Export the sums alleged or that Gazprom Export is legally entitled to compensation associated with the former Sakhalin interest.
The internal Shell documents examined in earlier instalments are distinguished from anonymous whistleblower accounts.
The authenticity of an internal document does not automatically establish the truth of every allegation or interpretation associated with it.
The British court decisions concerning environmental-information disclosure are not represented as judgments establishing Shell’s environmental liability.
Where original contracts, complete court records or underlying technical materials have not been independently obtained, conclusions are limited accordingly.
Editorial commentary is identified separately from established documentary findings.
Shell plc, Gazprom, Mitsui, Mitsubishi, former Sakhalin Energy personnel, relevant regulators and other interested parties are invited to submit factual corrections, additional original records or responses for consideration and publication.
The website’s general disclaimer also applies.

SLF-2007-111 — THE SAKHALIN PAPERS CI
The 1994 Agreement: The Contract Behind Twenty Years of Conflict
The hundredth investigation has identified the legal instrument at the centre of both major Sakhalin interventions.
The production-sharing agreement concluded on 22 June 1994.
It governed the development of the Piltun-Astokhskoye and Lunskoye fields.
It established the framework within which international investors committed billions of dollars.
It influenced the treatment of development costs.
And it remained central to the disputes concerning operating rights and obligations.
In December 2006, the parties announced that the agreement would continue after Gazprom acquired majority ownership.
In June 2022, the Russian presidential decree expressly referred to the same agreement while establishing a replacement operating company.
The next investigation will return to this original contractual foundation.
What protections did the agreement provide?
What obligations did it impose upon Sakhalin Energy?
How were development expenditure and cost recovery intended to operate?
What powers did Russian authorities retain?
What dispute-resolution arrangements applied?
And which claims about those rights can actually be supported by the surviving original documents?
The investigation will distinguish verified contractual provisions from retrospective descriptions, government assertions and legal interpretation. Where the complete agreement or relevant amendments cannot be independently authenticated, those limitations will be stated rather than filled with conjecture.
Twenty years of conflict cannot be understood without examining the contract that helped define the original relationship.
The Sakhalin Papers continue.
Editorial note: This hundredth instalment is structured as a documentary synthesis rather than a repetition of earlier files. Its central contribution is the comparison of the legal mechanisms used in 2006 and 2022, supported by original SEC filings, the text of the Russian decree and the subsequent financial record.
