In 2025, production averaged 5 kboepd from Indonesia.

Following the completion of our sale of our operated interests in Indonesia’s Natuna Sea Block A field and Tuna project, Harbour’s presence in the region is through its interests in the Andaman Sea discoveries.

Recent activity

In July 2025, Harbour completed the sale of its Vietnam business, including its operated Chim Sáo and Dua assets, resulting in an exit from the country. Upon completion of the sale of our operated interests in Natuna Sea Block A field and Tuna project in Indonesia in May 2026, Harbour’s presence in Southeast Asia is through its interests in the Andaman Sea discoveries. Harbour’s 2C resource for the Andaman area stood at 217 mmboe in 2025.
