Thailand greenlights new gas field to cut LNG imports
Thailand’s energy security received a significant boost on September 22, 2026, when PTTEP Energy Development Company Limited and Valeura Energy (Chaiyaphruek) Ltd. finalized their plan to develop the Bussabong gas field in the Gulf of Thailand. The project is set to deliver its first natural gas by the end of 2028 — a move that aims to reduce the country’s rising dependency on expensive imported liquefied natural gas.
Production will begin at 30 million standard cubic feet per day (MMSCFD) in 2029, climbing to 40 MMSCFD by 2030, enough to power nearly 1 million Thai households annually. This output will directly offset the steady decline of aging domestic gas fields, which have driven LNG imports up from 10% of supply in 2017 to 31% in 2023.
Key Facts
• Infrastructure: Two subsea wellhead platforms, each with 24 drilling slots, installed in 75–90 meters of water. Connected via a 9-kilometer, 12-inch pipeline to the existing North Bongkot processing hub — leveraging existing infrastructure to cut costs and timeline.
• Wells and Scope: Twenty-five new wells drilled in Phase 1; no new onshore facilities planned, minimizing land use conflicts and environmental disruption.
• Ownership: PTTEP holds 60% and operates the project. Valeura Energy holds 40% and will invest $35 million in surface facilities and pipelines, plus $20–25 million in drilling — all between 2027–2028. This marks Valeura’s first standalone gas development in Thailand.
• Impact on Households: In May 2026, imported LNG cost 28% to 40% more per unit than domestic pipeline gas. With gas fueling 60% of Thailand’s electricity and key industrial zones from Rayong to Songkhla, Bussabong will help stabilize the ‘Pool Gas’ price index used by utilities, reducing exposure to global volatility — though not lowering prices immediately.
Regulatory path and environmental context
Thailand’s Department of Mineral Fuels has approved the field’s defined production area. While no specific Environmental Impact Assessment (EIA) report has been publicly released for Bussabong, final approval requires standard government clearances, including reviews by environmental agencies.
Public concern remains focused on broader fossil fuel expansion. In mid-September 2026, Greenpeace Thailand organized demonstrations at Gastech in Bangkok, calling for urgent shifts to renewable energy. Though no local opposition has been documented for the Bussabong project itself, environmental groups continue to express caution toward new offshore fossil fuel infrastructure as climate pressures mount.
Future Expansion Plans
The project includes plans to drill an exploration well at the Nong Yao Northeast prospect within the same concession, potentially unlocking additional resources in the coming years. The phased, infrastructure-leveraging strategy could make Bussabong the first in a series of similar developments along the Gulf’s northern shelf — a potential long-term hedge against Thailand’s looming gas shortfall.
