Construction has begun on infrastructure to drill Sea Lion, an offshore oilfield 220km north of the Falkland Islands, with first oil expected by March 2028. The project could eventually produce 50,000 barrels daily and triple the territory's GDP, which currently relies heavily on squid and sheep farming.

Israeli company Navitas Petroleum and UK-based Rockhopper estimate peak annual government revenues could reach £280mn by 2034. This windfall would fund urgently needed infrastructure upgrades, including a new power station, wind turbines, and port facilities costing $350mn total. The Falklands has endured repeated power cuts in recent years.

Argentina's government reacted angrily to the development, with President Javier Milei calling it a unilateral and illegitimate attempt to exploit resources that belong to Argentina. Buenos Aires fought a two-month war with the UK over the islands in 1982 and continues to claim sovereignty. Energy majors previously avoided Falklands projects due to geopolitical risks, and Argentina successfully lobbied neighbors to blockade Falklands-flagged ships in 2011.

Analysts note the remote offshore development carries high fixed costs and remains sensitive to oil price volatility. Current Brent crude trades around $70 per barrel, while Navitas's break-even estimate sits near $24. The company has acquired additional drilling rights nearby, potentially creating a regional oil hub. Falklands officials acknowledge the project faces diplomatic headwinds but proceed cautiously after previous development failures.
