TGS Expands Sarawak Seismic Survey with Phase 4 Offshore Malaysia
Event summary
- TGS launches Sarawak Phase 4 multi-client program covering 1,020 sq km offshore Malaysia.
- Survey acquisition scheduled for Q4 2026, completion expected December 2026.
- Phase 4 is part of a larger contract to acquire up to 105,000 sq km of 3D seismic data in Sarawak.
- PETRONAS enhances data sets to explore pre-Middle Miocene Unconformity (MMU) play in deep-water areas.
- Project supported by industry funding.
The big picture
TGS's Sarawak Phase 4 expansion underscores the strategic importance of Southeast Asia's prolific hydrocarbon basins. The project aligns with PETRONAS's efforts to enhance exploration data, particularly in deep-water areas, reflecting broader industry trends toward leveraging advanced seismic technologies for resource assessment. The scale of the multi-client program positions TGS as a key player in the region's energy data intelligence market.
