TEMPO.CO, Jakarta – Indonesia’s Ministry of Energy and Mineral Resources has announced a major new oil and gas discovery in the Ganal Block, located off the coast of East Kalimantan, with estimated reserves of around 5 trillion cubic feet (Tcf) of gas and 300 million barrels of condensate.
The discovery was made from the Geliga-1 exploration well. The Ganal Working Area is operated by Eni, which holds an 82 percent stake, while Sinopec owns the remaining 18 percent.
Energy and Mineral Resources Minister Bahlil Lahadalia described the find as one of the largest oil and gas discoveries in recent years, signaling strong potential to bolster Indonesia’s energy supply amid rising demand.
“This is the result of exploration, and after this, Eni will continue development and further exploration in other areas,” Bahlil said at a press conference in Jakarta on Monday, April 20, 2026.
He projected that gas production from the project could increase significantly in the coming years. Output is targeted to reach around 2,000 million standard cubic feet per day (MMSCFD) by 2028, up from the current 600–700 MMSCFD, and could rise further to 3,000 MMSCFD by 2030.
Condensate production is also expected to climb. By 2028, output is projected to reach around 90,000 barrels per day, increasing to approximately 150,000 barrels per day between 2029 and 2030. The government hopes the additional production will help reduce Indonesia’s reliance on oil imports.
The Geliga-1 well was drilled to a depth of about 5,100 meters in waters roughly 2,000 meters deep. The discovery builds on Eni’s recent exploration successes in the Kutai Basin, including major finds at Geng North in 2023 and the Konta-1 well in 2025.
Bahlil said development of the Ganal Block will be integrated with other gas projects that have reached the Final Investment Decision (FID) stage, including Gendalo and Gandang (South Hub), as well as Geng North and Gehem (North Hub).
For the North Hub, Eni plans to deploy a Floating Production Storage and Offloading (FPSO) facility with a capacity of up to 1 billion cubic feet of gas per day and 90,000 barrels of condensate per day.
The project will also utilize existing infrastructure such as the Bontang LNG Plant to accelerate commercialization.
Previously, the ministry reported another discovery at the Gula well, with estimated reserves of around 2 Tcf of gas and 75 million barrels of condensate. Combined, the Geliga and Gula discoveries are expected to contribute up to 1,000 MMSCFD of additional gas production and 80,000 barrels of condensate per day.
“In addition to gas, by 2028 condensate production is estimated at around 90,000 barrels, and in 2029–2030 it could increase to about 150,000 barrels per day,” Bahlil said.
