Eni Indonesia has achieved exploration success in the Mahakam deepwater area of Indonesia and is now moving forward with plans to develop the discovered resources.
Eni’s Exploration Deepwater Drilling Success in Indonesia
Eni Indonesia has just made another big gas discovery at the Geliga-1 exploration well in East Kalimantan.
The Geliga-1 exploration well in the Ganal Block, offshore East Kalimantan, has revealed an estimated 5 TCF of gas and 300 million barrels of condensate. The block is operated by Eni, which holds an 82% stake, while Sinopec holds the remaining 18%.
Drilled to a depth of about 5,100 meters in 2,000 meters of water, the Geliga well adds to Eni’s strong track record in the Kutai Basin. It follows earlier major discoveries at Geng North (2023) and Konta-1 (2025), reinforcing the basin’s significant gas potential and resource stability.

The North Hub and South Hub Development
Global energy company Eni is advancing the development of the North Hub and South Hub gas projects.
It has approved the Final Investment Decision (FID) for the Gendalo–Gandang (South Hub) and Geng North–Gehem (North Hub) offshore gas projects in East Kalimantan, just 18 months after POD approval in 2024—highlighting rapid progress in Indonesia’s deepwater sector.
With over US$15 billion in investment, the projects will use existing infrastructure, including the Jangkrik FPU and Bontang LNG Train F, to reduce costs and speed up gas commercialization.
The Gendalo–Gandang development will involve 7 wells at depths of 1,000–1,800 meters tied to Jangkrik.
To develop the Geng North-Gehem, the company will drill 16 wells at 1,700–2,000 meters, feeding a new FPSO with a capacity of over 1 BCFD of gas and 90,000 BPD of condensate.
Combined resources are estimated at 10 TCF of gas and 550 million barrels of condensate. Production is expected to begin in 2028, peaking in 2029 at around 2 BSCFD of gas and 90,000 BPD of condensate.
Eni has operated in Indonesia since 2001 and is a major producer in the Kutai Basin, now a key gas hub in the Makassar Strait.
