Thailand Domestic Natural Gas Production Decline
~15–20% drop vs 2019 peak
Natural gas production from the Gulf of Thailand — the backbone of Thailand's power generation mix — has fallen an estimated 15–20% from its 2019 peak as ageing Erawan and Bongkot fields mature. The transition in the Erawan concession from Chevron to PTTEP in 2022 caused a temporary output disruption that pushed EGAT to procure additional LNG spot cargoes. Recovery drilling under PTTEP's redevelopment programme is ongoing, but analysts expect domestic gas to continue declining as a share of the country's total gas supply through 2030.
