Houlihan Lokey is pleased to announce that Harbour Energy (Harbour) has agreed to sell its 28.67% working interest in Natuna Sea Block A (NSBA) PSC and its 50% working interest in Tuna Block PSC to Prime Group for $215 million.

Harbour Energy is one of the world’s largest and most geographically diverse independent oil and gas companies. Harbour is currently producing more than 450,000 barrels of oil equivalent per day with significant production in Norway, the U.K., Germany, Argentina, and North Africa. Harbour benefits from competitive operating costs and resilient margins, and a broad set of growth options, including near-infrastructure opportunities in Norway, unconventional, scalable opportunities in Argentina, and conventional offshore projects in Mexico and Indonesia. Harbour is headquartered in London with approximately 3,400 employees and direct contract staff across its operations and offices.

Prime Group has upstream and downstream oil and gas businesses in Indonesia, including a 25% participating interest in the Natuna Sea Block B PSC, as well as interests in gas processing, crude oil and condensate trading, and refinery projects.

Harbour has a 28.7% operating interest in NSBA. NSBA produced c. 4.4 kboepd in the nine-month period to 30 September 2025. As of year-end 2024, Harbour had booked 2P reserves of 7.4 MMBOE in relation to its interest in NSBA.

Harbour has a 50% operating interest in the Tuna project, which is a development asset and has no production. As of year-end 2024, Harbour had booked 2C resources of 54 MMBOE in relation to its interest in the Tuna project.

Following completion of the transaction, Harbour will maintain a presence in Indonesia through its interests in the Andaman Sea discoveries.
