Sea Lion: the project that could almost quadruple Falkland Islands' GDP

An economic impact study calculates that the first two phases of the Sea Lion oil project—located north of the Falkland Islands—could add approximately US$10.942 billion to the islands' GDP over three decades.

These figures, when compared with an economy of just US$379 million annually, give an idea of the scale of the undertaking. However, it is important to note a key detail: the report was commissioned and financed by Navitas Petroleum, one of the two oil companies driving the project, and relies largely on production, cost, and employment information that the company itself provided to the consulting firm.

That report—the Economic Impact Assessment of the Sea Lion Northern Development Area Phase 1 and 2 Project, prepared by consulting firm Hatch in April 2025 and published on Navitas' institutional website—is today the primary public source on the deposit's impact on the islands. It has returned to the spotlight following President Javier Milei's announcement of new sanctions against companies exploiting hydrocarbons in the archipelago without Argentine authorization, along with reforms to Law 26.659, the creation of a National Security Council, and increased funding for the Integrated Naval Base in Ushuaia.

The deposit and timeline

Sea Lion is being developed by Israeli-based Navitas Petroleum and British-based Rockhopper Exploration. According to the Hatch study itself, the project has approximately 791 million barrels of recoverable resources. Navitas and Rockhopper made their final investment decision in December 2025, with the current schedule targeting first oil in March 2028, using an FPSO—a floating production, storage and offloading unit that will process and store crude before transferring it to tanker vessels for export.

This is a relevant detail for reading the projections: Hatch completed its analysis in April 2025, before the final investment decision. The report does not clarify whether GDP and revenue figures were updated to reflect the timeline announced later, so these should be taken as an estimate from that period rather than the most recent scenario.

Impact on GDP

Hatch uses an island GDP of approximately US$379 million in 2023 as its starting point, in an economy highly concentrated in fishing and aquaculture, which represented 58.6% of activity that year, while oil and gas still had marginal impact.

In the year of greatest impact, the figure would climb to approximately US$1.090 billion in additional GDP in a single year—around 290% of baseline GDP—driven mainly by the direct value added from oil production.

The report itself clarifies, however, that this jump in GDP does not equal net income for the islands: part of the oil companies' profits would be repatriated to their home countries, and a significant portion of specialized workers would come from abroad, meaning part of their income would also be transferred out of the territory.

An assumption that remains unclear. This entire projection depends, among other things, on the oil price assumed for the next 30 years—a variable the report acknowledges as determinant but which is not explicitly stated in the body of the publicly available document.

Fiscal impact: 9% royalties and up to US$4.869 billion for island administration

Beyond the GDP effect, Hatch calculates that taxes and royalties from phases 1 and 2 could provide the islands' administration with approximately US$4.869 billion cumulatively, with an average of US$147 million annually, concentrated mainly in the early years of highest production.

• Production royalty: 9%.

• Corporate income tax: between 21% and 26%, depending on each company's profit levels.

• Source of funds: slightly more than half would come from corporate income tax; the remainder from royalties.

To put this in perspective: the islands' total administration revenues were approximately US$162 million in the 2023/2024 fiscal year. The average annual projection for Sea Lion from taxes and royalties—US$147 million—is nearly equivalent to that entire figure.

The islands' own administration uses figures in line with this: a recent financial document estimates that Sea Lion could contribute approximately US$2.000 billion in royalties alone over 30 years, a figure consistent with the royalties portion within Hatch's total of US$4.869 billion. The islands already plan to establish a Sovereign Wealth Fund in 2029 to begin managing these resources starting in 2030.

Employment: up to 280 positions, but few filled by residents

The island labor market is small: the 2021 census recorded 1.881 employed persons between 15 and 64 years old. Within this framework, Hatch projects that Sea Lion could generate a maximum of 280 full-time equivalent jobs in 2027, including direct positions, contractor and supplier jobs, employment induced by worker spending, and positions related to infrastructure development. During the stable production phase, this number would drop to approximately 170 annual jobs.

The problem is that many of these positions require specializations that the local population does not possess. Of onshore jobs, only about 55 per year could be filled by residents; the rest would require foreign workers. This is in addition to an offshore workforce of up to 240 annual jobs between 2026 and 2033, declining to approximately 90 per year from 2034 onwards.

Migration and housing: the other bottleneck

The need for foreign labor has a direct demographic impact. Hatch estimates an average of 160 migrant workers per year, to which spouses and children in the more permanent positions would be added. The peak would occur between 2032 and 2033, with up to 250 new inhabitants associated with the project; it would then stabilize at a permanent increase of between 170 and 180 people, representing 5% to 6% of the reference population (3.662 inhabitants according to the 2021 census).

This growth clashes with a tight island real estate market with limited capacity for rapid expansion. Navitas plans to construct approximately 20 housing units for project workers, but Hatch calculates that by 2033 there could be a shortage of up to 84 additional homes, in addition to investment in public infrastructure, temporary accommodations, and transportation.

Caveats noted in the report itself

Hatch clarifies at the end of the document that much of the information supplied by Navitas and third parties was not independently verified, and that results depend on variables such as future oil prices, actual production levels, project costs, exchange rates, and the number of workers ultimately required to relocate from abroad. Any significant change in these variables could substantially alter the projected impact on GDP and tax revenues.

The political background

The report's figures are circulating at a moment of diplomatic tension. This week, Milei announced the tightening of sanctions against companies participating, directly or indirectly, in the exploitation of hydrocarbons and other natural resources in the archipelago without Argentine authorization, as part of Argentina's historical claim of sovereignty over the islands.
