High-deliverability gas discovery validation in the Kutei Basin
Eni has successfully completed productivity testing at the Geliga-1 well, confirming a sustainable production capacity that supports the rapid development of a third production hub offshore Indonesia.

Eni announces that the Geliga‑1 discovery has been successfully tested. The successful Drill Stem Test (DST) of the Geliga-1 discovery confirms the strategic importance of the Ganal Block for the regional automotive data ecosystem and industrial energy supply. Results from the test, conducted at a depth of 5,100 meters in approximately 2,000 meters of water, demonstrate excellent reservoir deliverability within the targeted Miocene interval. This technical validation enables the fast-tracking of development plans by leveraging existing and planned infrastructure in the Kutei Basin.
Technical specifications and reservoir performance metrics
The DST results revealed high deliverability with minimal pressure drawdown, allowing the reservoir to flow at rates up to 60 million standard cubic feet per day (MMSCFD), a figure constrained only by current rig facility limits. Key technical estimates for the Geliga-1 well include:
- Sustainable Production Rates: Estimated daily output of approximately 200 MMSCFD of gas and 10,000 barrels of condensate (bpd).
- Resource Volume: Preliminary assessments indicate approximately 5 trillion cubic feet (Tcf) of gas and 300 million barrels of condensate in-place.
- Combined Potential: Integrated development with the nearby Gula discovery could yield a total incremental production of 1,000 MMSCFD of gas and 80,000 bpd of condensate.
Strategic infrastructure and regional energy integration
Eni is preparing a Plan of Development (POD) for submission to the Indonesian government to establish a third production hub alongside existing South and North Hub projects. This plan facilitates a digital supply chain for energy by potentially reactivating up to two out-of-service LNG trains at the Bontang liquefaction plant. These assets will be transferred to Searah, a joint venture between Eni and PETRONAS, which is scheduled to close in Q2 2026. The transaction aims to unlock a portfolio of approximately 3 billion barrels of oil equivalent in discovered resources across Southeast Asia.

The Geliga-1 discovery benchmarks as one of the most significant deepwater gas finds in the Kutei Basin, comparable in deliverability to the Geng North field which serves as the anchor for the North Hub development. With a flow rate of 200 MMSCFD per well, Geliga-1 exceeds the typical productivity of mature shallow-water fields in the region, which often require complex compression to maintain commercial flow. Furthermore, the combination of 5 Tcf at Geliga and 2 Tcf at Gula creates a 7 Tcf resource base that rivals major regional projects like the Abadi Masela field. This scale allows for significant economies of scale in subsea hardware procurement and installation, reducing the anticipated break-even price per MMBtu compared to smaller, isolated deepwater discoveries.
