Perenco signed a gas sales and purchase agreement (GSPA) for the Su Tu Trang Phase 2B development in Block 15-1 offshore Vietnam, marking a key commercial milestone for a project aimed at boosting domestic gas supplies. The Su Tu Trang Phase 2B project is expected to supply more than 600 billion cubic feet (Bcf) of gas over its lifetime and produce up to 150 million standard cubic feet of gas per day (MMscfd) at peak output. The development includes brownfield modifications to existing facilities, the installation of a new Central Gas Facility platform, and the drilling of up to 15 gas wells. First gas is expected in June 2027, with plateau production targeted for June 2028. The agreement represents another milestone in the development of Block 15-1 following the renewal of the production sharing contract in 2025, which extended the partnership between Perenco, Petrovietnam, and PVEP by an additional 25 years.
