PETRONAS Announces Successful Hydrocarbon Discovery in East Java

While many energy players are diversifying their portfolios globally, Petronas is distinguishing itself through a highly concentrated and successful exploration strategy in Indonesia’s East Java basin. The recent hydrocarbon discovery at the Barokah-1 exploration well provides the company with a unique competitive edge, reinforcing its technical dominance in a region where it already maintains a robust infrastructure footprint. This successful find at the North Ketapang Production Sharing Contract (PSC) positions PETRONAS as a primary architect of Indonesia’s future energy landscape, contrasting with competitors who are still in the early appraisal phases of similar geological plays.

Technical Execution and Regional Synergy
The Barokah-1 well, located offshore East Java, reached a true vertical depth subsea of 3,315.3 metres following its commencement on 30 November 2025. This milestone is not an isolated success but rather a calculated expansion of Petronas’ existing regional operations. By integrating this new discovery with the momentum of the Hidayah Development Project — which reached its Final Investment Decision in late 2024 — the company is creating a localized energy hub that maximizes operational efficiency. Petronas holds a 51 per cent operating interest in the North Ketapang PSC, partnered with Earthon North Ketapang Pte. Ltd. (34 per cent) and PT. Pertamina Hulu Energi North Ketapang (15 per cent).

Strengthening the East Java Energy Portfolio
The discovery at Barokah-1 validates the high prospectivity of the Northern Madura region and enhances the geological understanding of the basin’s potential. This data-driven approach allows for disciplined growth, ensuring that new opportunities are matured in alignment with Indonesia’s broader energy requirements. Beyond North Ketapang, Petronas maintains an extensive operational network including the Ketapang, North Madura II, and Serpang PSCs offshore East Java, as well as the Bobara PSC offshore West Papua. This deep integration into the Indonesian upstream sector, supported by collaborative efforts with the Government of Indonesia, ensures a sustainable and responsible growth trajectory that few other international operators can match in the current market.
