Eni confirmed exceptional results in production tests at the Geliga-1 well, located in the Ganal Block, offshore Indonesia. The DST evaluation showed high reservoir productivity and reinforces the strategic value of the Kutei Basin for offshore gas development in Southeast Asia.
Geliga-1 reaches high gas production capacity
During the test, the evaluated interval achieved flow rates of up to 60 million standard cubic feet per day, limited by the platform facilities’ capacity. Most notably, the low pressure drawdown recorded is a technical indicator pointing to good reservoir connectivity and a deliverability higher than that observed during the initial test.
According to estimates derived from the test, the Geliga-1 well could sustain production of close to 200 million standard cubic feet per day of gas and around 10,000 barrels per day of condensate. This combination places the discovery among Eni’s most significant exploration and production assets in Indonesia.
A key discovery in the Kutei Basin
The Geliga-1 well is located about 70 kilometers off the coast of East Kalimantan, within the Ganal production sharing contract. It was drilled in waters approximately 2,000 meters deep and reached a total depth of nearly 5,100 meters.
In addition, the well intersected a significant gas column in a Miocene interval with favorable petrophysical properties. Test results maintain the preliminary estimate of approximately 5 trillion cubic feet of gas and 300 million barrels of condensate in place in the discovered interval.
This result is also connected to the nearby, still undeveloped Gula field. Gula has an estimated 2 trillion cubic feet of gas in place and 75 million barrels of condensate. Together, Geliga and Gula could support additional production of close to 1 billion standard cubic feet per day of gas and 80,000 barrels per day of condensate.
Accelerated development and LNG infrastructure
Eni is currently working on a Development Plan that it expects to submit to the Government of Indonesia in the coming weeks. The proposal seeks to accelerate a third production hub in the Kutei Basin, supported by existing infrastructure and planned facilities.
Likewise, the company is assessing the liquefaction capacity of the Bontang plant beyond what is included in the North Hub POD project. This review could enable the reactivation of up to two additional LNG trains that remain out of service, an important step to monetize new volumes of natural gas.
The new hub would complement the Gendalo and Gandang gas project, known as the South Hub, and the Geng North and Gehem fields, associated with the North Hub. This structure would allow Eni to build a more robust regional production platform in an area with high exploration potential.
Eni, Sinopec, and Searah strengthen their regional commitment
The Ganal PSC is operated by Eni with an 82% interest, while Sinopec holds the remaining 18%. This asset is part of a portfolio of 19 blocks that will be transferred to Searah, the company jointly controlled by Eni and PETRONAS.
The portfolio includes 14 blocks in Indonesia and 5 in Malaysia. Its business plan envisages the development of around 3 billion barrels of oil equivalent in discovered resources, in addition to new exploration opportunities. The transaction is expected to close in the second quarter of 2026.
For Eni, Geliga-1 comes at a pivotal time. The company, present in Indonesia since 2001, produces close to 90,000 barrels of oil equivalent per day in the country, mainly from the Jangkrik and Merakes fields. With Geliga-1, the Italian company adds an asset capable of increasing Indonesia’s weight within its global natural gas portfolio.
