Jakarta (ANTARA) – Indonesia has discovered a major natural gas reserve in East Kalimantan with an estimated 5 trillion cubic feet (Tcf) of gas and 300 million barrels of condensate, Energy Minister Bahlil Lahadalia said, underscoring efforts to boost domestic energy supply.“We are grateful for this discovery, and we must remain focused on carrying out the president’s directive to find new oil and gas sources,” Lahadalia told a press conference on Monday.The find was made at the Geliga-1 well in the Ganal Block, operated by Italy’s ENI, which holds an 82 percent stake, while China’s Sinopec owns the remaining 18.percent.The exploration highlights Indonesia’s untapped hydrocarbon potential, particularly in the Kutai Basin, a prolific area that continues to yield significant discoveries.“These are still exploration results, and further drilling will be expanded to other areas beyond East Kalimantan,” Lahadalia said.He added ENI’s production could rise sharply, with output projected to reach 2,000 million standard cubic feet per day (MMSCFD) by 2028, up from current levels of 600–700 MMSCFD.Production is expected to climb further to 3,000 MMSCFD by 2030, he said.The Geliga-1 well was drilled to a depth of around 5,100 meters in waters approximately 2,000 meters deep.The discovery builds on ENI’s recent successes in the region, including the Geng North field in 2023 and the Konta-1 well in 2025.It follows final investment decisions for several projects, including Gendalo and Gandang under the South Hub, and Geng North and Gehem under the North Hub.The North Hub development will use a new floating production storage and offloading (FPSO) facility with a capacity of one billion cubic feet of gas per day and 90,000 barrels of condensate per day.Existing infrastructure, including the Bontang LNG refinery, will also be utilized.In addition to Geliga, Lahadalia cited the earlier Gula well discovery, which holds about 2 Tcf of gas and 75 million barrels of condensate.Combined, the two wells could add up to 1,000 MMSCFD of gas and 90,000 barrels per day of condensate production.The government aims to accelerate development to production, expecting the project to boost investment, create jobs, raise state revenues and strengthen national energy security.
