Eni has announced that the Geliga-1 discovery has been successfully tested. A Drill Stem Test (DST) was carried out, confirming outstanding reservoir productivity. Test results demonstrate high deliverability, further strengthening the strategic potential of Indonesia’s Kutei Basin and supporting accelerated development options leveraging existing and planned infrastructure.
During DST, the tested reservoir flowed at rates of up to 60 million standard cubic feet per day (MMSCFD), constrained by the rig facilities, and with very limited pressure drawdown, confirming excellent deliverability. Based on the DST results, the Geliga-1 well is estimated to produce a sustainable rate of approximately 200 MMSCFD of gas and about 10,000 barrels per day (bpd) of condensate.
Geliga-1 is situated in the Ganal Block within the Kutei Basin, offshore Indonesia, about 70 km off the coast of East Kalimantan. Drilled in approximately 2,000 m of water, the well reached a total depth of about 5,100 m and intersected a substantial gas column in the targeted Miocene interval, characterized by excellent petrophysical properties. The well test results further confirm the preliminary assessment of approximately 5 trillion cubic feet (Tcf) of gas and 300 million barrels of condensate in-place within the encountered interval.
The new discovery is located next to the undeveloped Gula gas discovery, estimated at approximately 2 Tcf of gas in place and 75 million barrels of condensate. Early evaluations indicate that, when combined, Geliga and Gula could underpin incremental production of around 1,000 MMSCFD of gas and 80,000 bpd of condensate.
A Plan of Development (POD) is currently being prepared and is expected to be submitted to the Government of Indonesia in the coming weeks. The POD aims to enable the fast-track development of a third production hub in the prolific Kutei Basin, alongside the Gendalo and Gandang gas project (South Hub) and the Geng North and Gehem fields (North Hub), by leveraging the development concept currently being implemented for the North Hub project.
In parallel, studies are underway to assess liquefaction capacity at the Bontang plant beyond that already included in the North Hub POD, potentially enabling the reactivation of up to two additional LNG trains currently out of service.
The Geliga-1 discovery is located in the Ganal PSC, operated by Eni with an 82% interest, while Sinopec holds the remaining 18%. The Ganal PSC is included in a portfolio of 19 blocks (14 in Indonesia and 5 in Malaysia) that will be transferred to Searah, the Eni–PETRONAS jointly controlled company announced in November 2025. Searah will combine assets, technical know-how and financial capacity to support growth and reinforce its presence in Southeast Asia. Its business plan includes the development of approximately 3 billion barrels of oil equivalent (boe) of discovered resources, alongside the unlocking of significant exploration potential. Transition and set-up activities are progressing smoothly, with no critical issues currently anticipated. The transaction closing remains confirmed for Q2 2026. The valorization to a third party of a 10% stake in the Eni Indonesia portfolio withheld from the Searah transaction is underway and expected to be concluded in 2026. The Geliga discovery adds to the value of this sale.
Eni has been present in Indonesia since 2001 and currently holds a diversified upstream portfolio across exploration, development and production activities. Net production is approximately 90,000 barrels of oil equivalent per day, mainly from the Jangkrik and Merakes fields offshore East Kalimantan.
