Argentina is preparing to file criminal charges against Navitas Petroleum and several companies linked to its Falklands oil operations, escalating a long-running dispute with the United Kingdom over sovereignty and natural resources in the South Atlantic.
The government of President Javier Milei says the companies are operating under hydrocarbon licenses issued by the United Kingdom in the North Falkland Basin, which Argentina considers part of its territory. The planned legal action comes as the major Sea Lion oil project moves closer to development.
Argentina Accuses Oil Firms of Violating National Law
Argentina’s Foreign Minister Pablo Quirno is expected to submit the criminal complaint against several Navitas entities, along with other companies involved in the project. The complaint also targets directors, managers and representatives who may have participated in the activities under investigation.
Buenos Aires argues that the companies’ UK-issued licenses conflict with Argentina’s Law 26.659, which regulates hydrocarbon activities connected to areas claimed by Argentina. The government says the legal action is intended to protect what it considers Argentine natural resources and sovereignty.
The move follows Milei’s recent pledge to impose tougher measures on companies involved in oil exploration around the Falkland Islands, known as the Malvinas in Argentina.
Sea Lion Oil Project at the Center of the Dispute
The Sea Lion offshore oil field has become a major focus of the latest disagreement. Navitas Petroleum operates the project and owns a 65% interest, while UK-listed Rockhopper Exploration holds the remaining stake.
The project is expected to require significant investment and is currently targeting its first oil production in 2028. Its development has increased the economic importance of the decades-old sovereignty dispute, particularly because the field is believed to contain substantial oil resources.
Navitas and Rockhopper have maintained that their licenses were legally granted by the Falkland Islands government. The companies have also indicated that the latest Argentine measures do not currently alter their plans for the project.
Falklands Sovereignty Dispute Intensifies
The planned criminal proceedings add another layer to the long-running Argentina-UK Falklands dispute, which has remained unresolved since the two countries fought a war over the islands in 1982.
Britain continues to assert sovereignty over the Falkland Islands and has emphasized the right of residents to determine their own political future. In a 2013 referendum, an overwhelming majority of islanders voted to remain a British Overseas Territory.
For Argentina, however, the islands remain a central sovereignty issue. Milei’s government has increasingly linked the territorial claim with control over offshore oil and other natural resources.
The latest criminal complaint is therefore likely to further increase diplomatic tensions between Buenos Aires and London as the Sea Lion project progresses toward production.
