Key points
- Petronas extended the Temaris cluster production sharing contract by 547 square kilometres.
- The total contract area now covers approximately 1,770 square kilometres.
- Seascape plans to process new 3D seismic data and drill a contingent exploration well.
- An updated Competent Person Report from Sproule ERCE is expected in the fourth quarter of 2026.
What happened
According to Offshore Energy, Malaysia's state-owned oil and gas enterprise, Petronas, has awarded Seascape Energy a 45 percent extension to its production sharing contract in shallow waters offshore Peninsular Malaysia. The agreement was issued via Malaysia Petroleum Management, enlarging the original Temaris cluster footprint by 547 square kilometres to the north and east. This brings the total contract area to approximately 1,770 square kilometres.
Seascape originally secured the acreage in June 2025 through the Malaysia Bid Round. Following a subsurface review and 3D seismic reprocessing, the operator identified a continuation of the Miocene channelised sandstone play located near the Tembakau and Mengkuang gas discoveries.
Why it matters
Pierre Eliet, Malaysia Country Chair and Executive Director at Seascape, noted that the portfolio addition aligns with shifting industry priorities regarding Asian gas markets. Sproule ERCE is currently updating a previous Competent Person Report that estimated 950 billion cubic feet of gross mean prospective resources across the property. The updated report is scheduled for release in the final quarter of 2026.
What comes next
Obligations for the expanded acreage include processing new 3D seismic data and drilling a contingent exploration well, funded through existing cash reserves. Seascape has also resumed a farm-out process to secure a partner prior to submitting a field development plan before the end of 2026, subject to final documentation.
