Seascape Energy, an E&P company focused on Southeast Asia, has announced that the joint venture partners in Deepwater Block 2A PSC located off the coast of Sarawak, offshore Malaysia, have approved entry into the second exploration phase of the PSC and drilling of the giant Kertang prospect, subject to Petronas MPM formal approval.
Formal commitment allows the joint venture to now focus on securing a suitable drilling rig and identifying the precise drilling location to test the Kertang structure which has over 200 km2 of four-way dip closure and total unrisked mean prospective resources in excess of 9 TCF, based on a CPR undertaken by ERCE Sproule.
Seascape anticipates the Kertang well to be part of a wider deepwater exploration drilling campaign across multiple blocks in Malaysia during 2026 and 2027 to be undertaken by Block 2A operator INPEX CORPORATION. Seascape will provide further details regarding the anticipated timing of drilling once available.
The second exploration phase includes a firm, minimum work commitment of one wildcat exploration well and one contingent appraisal well. Seascape, through a wholly owned subsidiary, remains fully carried by INPEX CORPORATION on an uncapped basis through the entire second exploration phase on its retained 10% participating interest, providing shareholders with material exposure to the Kertang prospect at nil cost.

Nick Ingrassia, CEO of Seascape, commented:
'The firm commitment to drilling the world-class Kertang prospect on Block 2A, one of the largest undrilled structures in Malaysia, is an important step not only for Seascape and the Block 2A partners but also for testing the significant potential for giant gas discoveries in the wider North Luconia basin, off the coast of Sarawak, offshore Malaysia, which has seen some of the highest exploration success rates in Southeast Asia in recent years.
We would like to thank the operator, INPEX CORPORATION, our joint venture partners PETRONAS Carigali and PETROS, along with PETRONAS MPM for the excellent work and collaborative approach in reaching this important point in such a short period of time.
Seascape remains focused on maintaining momentum across its portfolio into 2026 and beyond, exposing shareholders to the significant upside available across its existing portfolio, including the recently secured Temaris PSC, and multiple growth opportunities it is currently pursuing.'
Block 2A Highlights
Block 2A is located off the coast of Sarawak, offshore Malaysia in the North Luconia hydrocarbon province covering approximately 12,000 km2 in water depths between 100 -1,400 metres. Block 2A contains the world-class Kertang prospect, located across four Oligo-Miocene reservoirs, which is:
- Well-defined, large, four-way dip structural high with over 200 km2 of closure;
- Covered by high-quality, wide-beam 3D seismic shot by CGG in 2015;
- Exhibits direct hydrocarbon indicators (DHIs) including an overlying gas cloud feature and amplitude brights;
- CPR undertaken by Sproule ERCE on Kertang in 2024 assigns total gross, unrisked mean prospective resources of 9.1 TCF plus 146 mmbbl of NGLs (~1.7 billion boe);
- CPR chance of success of ~20%;
- Bintulu LNG, one of the world's largest LNG facilities, is located onshore Sarawak.
