Geliga‑1 gas discovery

Eni said on April 20 it had made a major gas discovery at the Geliga-1 well offshore East Kalimantan, Indonesia. (eni.com) The well sits in the Ganal block in the Kutei Basin, about 70 kilometers off East Kalimantan’s coast. Eni said preliminary estimates point to about 5 trillion cubic feet of gas in place and 300 million barrels of condensate. (eni.com) Geliga-1 was drilled to roughly 5,100 meters in about 2,000 meters of water and hit a gas-bearing Miocene reservoir with what Eni called strong rock quality. The company said it plans a drill stem test, a production trial used to measure how much oil or gas a reservoir can actually flow. (eni.com) Condensate is a light liquid hydrocarbon that comes out with gas and can raise a project’s value because it can be sold like very light oil. In-place resources are not the same as recoverable reserves, because companies still have to test flow rates, design facilities and win approvals before booking commercial volumes. (eni.com) The find adds to a run of deepwater discoveries by Eni in the same basin, including Geng North in October 2023 and Konta-1 in December 2025. Eni said in March 2026 that it had already taken final investment decisions on the Gendalo-Gandang and Geng North-Gehem projects offshore East Kalimantan. (eni.com 1) (eni.com 2) (eni.com 3) That development plan matters because Eni is trying to tie new offshore finds back to existing infrastructure instead of building every project from scratch. The company said its East Kalimantan strategy uses the Jangkrik floating production unit and the Bontang liquefaction plant to speed development and cut costs. (eni.com) Petronas is part of the story beyond a single well. The Malaysian state energy company and Eni signed an investment agreement in November 2025 to create a regional upstream venture spanning selected assets in Malaysia and Indonesia after earlier framework talks in June 2025 and a memorandum in December 2024. (petronas.com 1) (petronas.com 2) (petronas.com 3) Eni has operated in Indonesia since 2001 and said in August 2024 that its equity production in East Kalimantan was about 95,000 barrels of oil equivalent a day. Indonesian authorities also approved plans of development for several Kutei Basin projects in 2024 and extended the Ganal and Rapak licenses by 20 years. (eni.com) The next test for Geliga-1 is no longer whether hydrocarbons are present, but how quickly Eni and its partners can turn another Kutei Basin discovery into flowing gas. (eni.com)
