PTTEP sanctions Sirung and Chenda developments offshore Malaysia for 2028 start-up
PTTEP has taken a final investment decision on the Sirung and Chenda fields in Malaysia’s offshore SK405B project, targeting first production in 2028 and output of 15,000 barrels per day. The company also raised Gulf of Thailand gas production to about 2,720 MMscf/d during the first quarter of 2026.
PTTEP has approved development of the Sirung and Chenda fields in the Malaysia SK405B project, marking what the company described as its first final investment decision for a greenfield development in Malaysia. First production is scheduled for 2028, with planned oil output of 15,000 barrels per day.
The sanction establishes a new offshore development milestone in PTTEP’s Malaysian portfolio and could generate future demand for drilling, subsea, construction and production-related services. The release did not disclose development costs, the production concept, facility requirements or a contracting schedule.
In Thailand, PTTEP said it accelerated production from Gulf of Thailand projects in response to volatile global energy markets. Output reached approximately 2,720 million standard cubic feet per day, compared with a combined daily contractual quantity of around 2,500 MMscf/d. The additional volumes came primarily from the Arthit, MTJDA B17-01, Contract 4 and G2/61 projects.
PTTEP reported first-quarter average sales of 553,369 barrels of oil equivalent per day, approximately 14% above the corresponding 2025 period. The increase reflected higher domestic production and contributions from the MTJDA A18, Algeria Touat and Malaysia SK408 projects acquired during 2025. Quarterly revenue was THB78.84 billion, while net income reached THB11.84 billion.
