PTTEP moves forward with Bussabong gas field

Tuesday, September 22 2026

Gas Production

PTTEP has announced the Final Investment Decision (FID) for the Bussabong gas field in the G3/65 Project, with first natural gas production targeted for 2028 to support Thailand’s growing energy demand.

This marks the next stage following the successful natural gas discovery, advancing the project from exploration to development.

The development is expected to take approximately two years, with first gas production targeted for 2028 at a rate of around 30 million standard cubic feet per day (MMSCFD), increasing to 40 MMSCFD by 2030 to help meet the country’s growing energy demand.

For the development of the Bussabong gas field in the G3/65 Project, PTTEP plans to produce natural gas through a subsea pipeline system connected to the Central Processing Platform (CPP) and production facilities of the nearby North Bongkot field in the G2/61 Project, which is operated by PTTEP.

Leveraging this existing infrastructure will enable the Bussabong gas field to be developed more efficiently and expeditiously. The development plan will proceed following approval of the relevant agreements by the government authorities.

In addition, the company plans to conduct further exploration activities in other areas of the G3/65 Project, including drilling an exploration well in the Nong Yao Northeast prospect to further assess the petroleum potential. A successful discovery could provide an opportunity to increase the G3/65 Project’s production capacity in the future.

PTTEP was awarded petroleum exploration and production rights for the G3/65 Project under a Production Sharing Contract (PSC) in 2023 and serves as the operator.

The project covers an area of approximately 11,647 square kilometers. Following the satisfaction of conditions precedent under the Farm-out Agreement, PTTEP holds a 60% participating interest and remains as the operator, while Valeura Energy (Chaiyaphruek) Ltd. holds a 40% participating interest.
