The parties also signed a Gas Sales Agreement (GSA) with Petroliam Nasional Berhad (PETRONAS) and PTT Public Company Limited, supporting the continued supply of natural gas from the block to both countries.
The exchange ceremony of the signed agreements on September 14, 2026 marks the culmination of extensive collaboration among the Malaysia-Thailand Joint Authority (MTJA), PC JDA, and PTTEP JDX to establish a new contractual framework linking the continued development of the existing Block A-18 (beyond the expiry of the current PSC on April 20, 2029) while incorporating an adjacent exploration area with an additional resource potential under the new PSC.
With a 35-year term commencing from January 1, 2026, the new PSC for Block A-18-01 encompasses both the existing Block A-18 area and the additional new area, providing an integrated platform to sustain production, unlock further resource potential, and optimize the block’s long-term development.
Director of PC JDA, Ainoor Abizzurin B Abdullah said, “The approval of the new PSC ushers in the next phase of development for Block A-18-01, reflecting the enduring resolve and strong collaboration between Malaysia and Thailand. As a key source of natural gas and condensate for both countries, this milestone reinforces our shared commitment to maximize value through enhanced resource monetization and operational synergies.”
Spanning approximately 7,250 square kilometers, the MTJDA comprises Blocks A-18-01 and B-17-01, which have a combined natural gas production capacity of approximately 700 million standard cubic feet per day with equal distribution to Malaysia and Thailand.
Block A-18-01 comprises the Cakerawala, Bumi, Suriya, Bulan, South Bulan, Senja, East Bumi, Samudra, and Wira gas fields, including the open area. Meanwhile, Block B-17-01 comprises the Muda, Tapi, Tanjung, Amarit, Jengka, Melati, and Andalas gas fields.
The new PSC reinforces PETRONAS Carigali’s commitment to investing in strategic assets and pursuing sustainable growth for regional energy security.
