Executive summary

Major international oil companies, most notably ConocoPhillips and others operating joint ventures in 2007, had large stakes in Venezuelan projects — including Petrozuata, Hamaca and Corocoro — that Caracas expropriated when Hugo Chávez nationalized oil fields, a move the companies said occurred without compensation [1]. Those seizures spawned long-running arbitration and enforcement actions that as of 2025 produced rulings worth about $8.7 billion plus interest and U.S. authorizations allowing firms such as ConocoPhillips to pursue Venezuelan assets abroad [1].

1. The 2007 nationalizations: what was taken and who cried foul

In 2007 Chávez’s government moved to nationalize large foreign-operated oil projects; ConocoPhillips reported its stakes in three major ventures — Petrozuata, Hamaca and Corocoro — were seized without compensation as part of that campaign [1]. Contemporary U.S. and international reporting frames these expropriations as the central grievance behind later litigation and political rhetoric about “stolen” assets [2].

2. Legal fallout: arbitration awards and enforcement

Those nationalizations led to arbitration and court proceedings that persisted for years. By 2025 arbitration rulings that had been upheld totaled roughly $8.7 billion plus interest, and Venezuela has consistently refused to pay, prompting measures to enforce awards overseas [1]. The U.S. Treasury’s permission for ConocoPhillips to seek enforcement worldwide is a direct consequence of that legal process [1].

3. Why companies lost control — Caracas’s rationale

Venezuelan policy under Chávez emphasized reclaiming control over hydrocarbon wealth and maximizing state ownership. The 2007 actions were presented by the government as nationalizations of fields and projects to restore sovereignty over oil resources; coverage notes the expropriations occurred amid rising oil prices and broader state takeovers of strategic assets [1].

4. Business context: investments, partnerships and risk

International oil companies had invested heavily in long-term, capital-intensive projects in Venezuela. For firms such as ConocoPhillips, the seized stakes represented multibillion‑dollar sunk investments and operating control of production ventures — which is why companies pursued international arbitration and enforcement when Caracas moved to assert state ownership [1].

5. Political context and later U.S. actions

The historical expropriations inform contemporary U.S. policy and rhetoric. In 2025, U.S. officials and politicians invoked past seizures when discussing sanctions, tankers and even the seizure of Venezuelan vessels; reporting ties claims of “stolen” assets to the documented 2007 expropriations that prompted legal awards [1] [2]. The seizure of a sanctioned tanker in December 2025 and talk of blockades further amplified references to earlier asset disputes [3] [4].

6. Competing narratives and what sources emphasize

Corporate and Western sources emphasize that foreign firms were deprived of compensation and thus sought redress through arbitration [1]. Venezuelan authorities framed the moves as sovereign nationalizations to reclaim hydrocarbons, a justification noted in contemporaneous reporting though not fully detailed in the sources provided here [1]. Available sources do not mention internal Venezuelan legal arguments in detail beyond the fact of nationalization (not found in current reporting).

7. Stakes today: dollars, diplomacy and enforcement tools

The summed arbitration awards of about $8.7 billion plus interest underscore why enforcement matters: multibillion-dollar judgments motivate asset seizures, sanctions, and U.S. authorizations to pursue Venezuelan holdings abroad [1]. That legal-economic thread connects the 2007 expropriations to present-day measures such as targeted seizures of tankers and expanded sanctions on oil shipping networks [3] [5].

8. Limits of the record and open questions

The sources provided identify ConocoPhillips and the three named ventures as central examples and document related arbitration outcomes, but they do not provide a comprehensive list of every international oil company affected or the full range of Venezuelan justifications and compensation offers [1]. Available sources do not mention which other specific companies beyond ConocoPhillips lost assets in 2007 in this excerpt (not found in current reporting).

9. Bottom line for readers

The expropriations under Chávez are documented, produced multi‑billion‑dollar arbitration awards in favor of foreign investors, and remain a live element in U.S.–Venezuela confrontations and enforcement actions; ConocoPhillips’ seized stakes in Petrozuata, Hamaca and Corocoro are the clearest, sourced example in current reporting [1].
