PTT Exploration and Production Public Company LimitedPTTEP secures 35-year PSC rights for Block A-18-01, adding ~300-400 MMcf/d gas production capacity and extending its operated acreage.

PTTEP has taken over the production sharing contract, or PSC, rights for Block A-18-01 in the Thailand-Malaysia Joint Development Area from the Malaysia-Thailand Joint Authority, or MTJA. Prime Minister Anutin Charnvirakul and Energy Minister Ekkanat Promphan attended the ceremony, held at the Gastech Exhibition & Conference 2026 at the BITEC exhibition and convention centre in Bangkok. The rights holders are PTTEP JDX Thailand (JDA) Limited and PTTEP JDX Thailand Company Limited, both subsidiaries of PTTEP, and PC JDA Limited, a subsidiary of PETRONAS Carigali Sdn Bhd. Each party holds a 50 percent investment share to carry out exploration, development and production of petroleum in Block A-18-01 for a further 35 years, with the contract effective retroactively from 1 January 2026. This contract replaces the previous production sharing contract and covers the original area of Block A-18 as well as new acreage. Natural gas production capacity is approximately 300 to 400 million cubic feet per day, delivered to Thailand and Malaysia in equal proportions. The gas supplied to Thailand accounts for roughly 4 percent of domestic gas demand and is used as fuel for power generation in southern Thailand. Montri Lawanchaikul, Chief Executive Officer of PTTEP, said the acquisition of these rights will help maintain continuity of natural gas production for both countries and allows further development of Block A-18-01 together with Block B-17-01, in which PTTEP and PC JDA are already joint investors. The two blocks currently produce a combined total of about 700 million cubic feet of gas per day. The Thailand-Malaysia Joint Development Area is located in the lower part of the Gulf of Thailand and covers a total area of approximately 7,250 square kilometres.
