ENEOS Xplora, in partnership with operator Petronas Carigali, is working to accelerate the development of the BIGST Cluster offshore Peninsular Malaysia. The project is critical for national energy security, with phase one expected to supply 30% of Peninsular Malaysia's gas demand upon completion.

Project Timeline and Development Phases

The final investment decision for phase one is targeted for next year, with first gas expected in 2029. Carbon dioxide injection for this phase is planned for the early 2030s. The front-end engineering and design decision for phase one was taken last year. For phase two, the FEED decision is expected in 2028, the FID in 2033, and CO2 injection in 2038. The partners aim to speed up development to match the timing of a regional gas shortage, a situation exacerbated by energy market volatility and geopolitical turbulence in the Middle East.

Technical and Commercial Considerations

Project economics are complicated by geologically complex subsurface uncertainty. ENEOS aims to overcome this through technical collaboration with Petronas Carigali. The development model mirrors the Kasawari project, featuring a large central processing platform and a separate CO2 injection platform for the carbon capture and storage component. Natural gas will be transferred to a gas terminal for sale. Phase one will include small-scale gas production, with the FEED for the CO2 compressor to follow later as exact carbon dioxide volumes are currently unknown.

Future Outlook and Project Background

ENEOS is focused on the BIGST project and, upon its success, will consider expanding to future CCS projects in the region. The BIGST Cluster, comprising the Bujang, Inas, Guling, Sepat, and Tujoh gas discoveries, is operated under a production sharing contract secured by the 50:50 joint venture from Malaysia Petroleum Management in 2024.
