Dec 8 (Reuters) - Harbour Energy on Monday agreed to sell its operated interests in the Natuna Sea Block A field and the Tuna development project in Indonesia to oil and gas firm Prime Group for $215 million.
Harbour holds a 28.67% operated interest in Natuna Sea Block A, which produced about 4,000 barrels of oil equivalent per day in the nine months ended September, and a 50% operated interest in the Tuna project.
Prime Group has upstream and downstream operations in Indonesia, including a 25% interest in the Natuna Sea Block B field.
The deal, targeted for completion in the second quarter of 2026, will leave Harbour with continued exposure to Indonesia through its interests in the Andaman Sea discoveries.
