Eni Confirms Strategic Potential of Indonesia’s Kutei Basin

20 Apr Eni Confirms Strategic Potential of Indonesia’s Kutei Basin

(Oilandgaspress) -– Eni announces a new giant gas discovery made by the Geliga‑1 exploration well, drilled in the Ganal block in the Kutei Basin, offshore Indonesia, approximately 70 km from the East Kalimantan coast. Preliminary estimates indicate in-place resources of approximately 5 trillion cubic feet (Tcf) of gas and 300 million barrels of condensate in the encountered interval.

The Geliga‑1 well was drilled to a total depth of around 5,100 meters in a water depth of about 2,000 meters and encountered a significant gas column in the targeted Miocene interval, characterized by excellent petrophysical properties. A Drill Stem Test (DST) is planned to assess the productivity of the reservoir. The Geliga‑1 discovery is part of a highly successful exploration track record in the Kutei Basin and follows the Geng North giant discovery made in late 2023 only 20 km south of Geliga, as well as the more recent Konta‑1 well discovery announced in December 2025. These results confirm the significant potential of the basin’s gas play and the scalability of resources in the area.

The Geliga‑1 discovery also follows the recent Final Investment Decisions (FIDs) for the Gendalo and Gandang gas project (South Hub), and for the Geng North and Gehem fields (North Hub). The North Hub project will leverage a newly built FPSO with a handling capacity of 1 bscfd of gas and 90,000 bpd of condensate, as well as the existing Bontang LNG Plant.

Analyses are ongoing to evaluate accelerated development options, also considering the proximity to existing and planned infrastructures, which offer potential synergies in terms of time‑to‑market and cost optimization. The new discovery is adjacent to the not‑yet‑developed Gula gas discovery (2 Tcf of gas in place with 75 million barrels of condensate). Initial assessments indicate that the combined Geliga and Gula resources have the capacity to produce an additional 1 bscfd of gas and 80,000 bpd of condensate, opening the possibility—among others—of establishing, in a fast‑track mode, a third production hub in the prolific Kutei Basin by mirroring the development concept of the ongoing North Hub project. Studies are also underway to evaluate a further rejuvenation of Bontang by resuming additional liquefaction capacity beyond what is already planned for the North Hub development, thus further extending the plant’s operational life.
