PETRONAS, through its subsidiary PETRONAS North Ketapang Sdn. Bhd. has made its first hydrocarbon discovery at the Barokah-1 exploration well located within the North Ketapang Production Sharing Contract , offshore East Java, Indonesia.

PETRONAS is the operator of the North Ketapang PSC with a 51 per cent participating interest, while Earthon North Ketapang Pte. Ltd. holds 34 per cent participating interest, and PT. Pertamina Hulu Energi North Ketapang holds 15 per cent participating interest.

The Barokah-1 well was spudded on 30 November 2025 and successfully drilled to a true vertical depth subsea of 3,315.3 metres. Further studies will be undertaken to fully evaluate the well results and determine the discovery’s potential.

PETRONAS Vice President of Exploration, Ahmad Faisal Bakar, said the discovery reinforces PETRONAS’ long-standing presence in East Java.

“The Barokah-1 discovery reinforces the compelling exploration potential we continue to see in the Northern Madura region, East Java. This encouraging result deepens our understanding of the basin’s prospectivity and strengthens PETRONAS’ drive for disciplined growth and to mature opportunities that can contribute to East Java’s durable energy landscape.”

This milestone complements the momentum of the ongoing Hidayah Development Project from the North Madura II PSC, which reached Final Investment Decision (FID) in October 2024 following an oil discovery in 2021.

President Director of PETRONAS North Ketapang Sdn. Bhd., Yuzaini Md Yusof, expressed his appreciation for the strong support received from stakeholders throughout the exploration activities.

“We are grateful to the Government of Indonesia and partners for their collaboration in enabling the drilling programme’s success, as we pursue responsible upstream growth that contributes to Indonesia’s energy sector.”

Beyond the North Ketapang PSC, PETRONAS operates the Ketapang, North Madura II, and Serpang PSCs offshore East Java, as well as the Bobara PSC offshore West Papua, and holds participating interests in six PSCs located onshore and offshore Sumatra, the Natuna Sea, East Java, and East Indonesia.
