Transaction Overview: Harbour Energy has agreed to sell its interests in the Natuna Sea Block A field and the Tuna development project in Indonesia to Prime Group for $215 million, including a 28.67% interest in Natuna and a 50% interest in Tuna.
Production and Reserves: The Natuna Sea Block A produced approximately 4,000 barrels of oil equivalent per day, with proved plus probable reserves of 7.4 million barrels, while Tuna holds contingent resources of 54 million barrels.
Completion Timeline: The transaction is expected to finalize in the second quarter of 2026, pending regulatory approvals, with the effective date for Natuna set for January 1, 2025.
Strategic Shift: This sale is part of Harbour's strategy to focus on more competitive opportunities, following recent workforce reductions in the UK due to government policies affecting the North Sea fossil fuel industry.
