Summary:

• Navitas Petroleum plans to accelerate development of the Sea Lion oilfield with investment reaching around $3 billion.

• A second production vessel could produce 125,000 barrels of oil daily, with first output expected by 2030.

• The first vessel is scheduled to begin production in March 2028, producing around 55,000 barrels per day.

• Navitas owns 65% of Sea Lion, while UK-listed Rockhopper Exploration holds the remaining 35%.

• Sea Lion lies 136 miles north of the Falklands and is estimated to contain around 900 million barrels.

• The Falkland Islands Government will receive a 9% revenue royalty and levy 26% corporation tax on profits.

• The initial development phase, targeting approximately 170 million barrels, is estimated to cost $2.1 billion.

• Expansion into the field's central area could access another 403 million barrels and raise investment to approximately $3 billion.

• Argentina continues to claim sovereignty over the Falklands, while islanders overwhelmingly voted to retain British status in 2013.

• Rockhopper plans to raise capital to finance its share of the second vessel acquisition and further development.

What’s next: Initial production is planned for 2028, followed by expanded output from the second vessel around 2030.
