State-controlled South Korean oil firm KNOC has secured a 25-year extension to its production sharing contract (PSC) for Vietnam's Block 15-1, locking in its participation in the offshore asset until 2050.
The 15-1 block, which is operated by state-owned PetroVietnam, is located in the Cuu Long basin, and produces around 34,000 b/d of crude oil, primarily from the Black Lion field.
The project partners plan to invest $1.3bn for the White Lion gas field region within the block, which aims to supply 125mn ft³/d of natural gas to Vietnam's market. No timeline has been given for when the field will reach this production level.
The extension, signed in liaison with Petro Vietnam's upstream arm PVEP, comes ahead of the expiry of the existing PSC in September 2025. It covers continued development of oil fields within the block and the second-phase development of the White Lion gas field.
KNOC holds an 11.4pc stake in the extended PSC. PVEP remains the majority stakeholder with a 59pc interest. Other partners include South Korean oil exploration firm SK Earthon, Monaco's Geopetrol and UK-French oil and gas company Perenco.
