Indonesia discovery yields strong productivity tests for Eni

SAN DONATO MILANESE, May 7, 2026 – A drill stem test at Eni’s Geliga-1 gas discovery offshore Indonesia has confirmed “outstanding reservoir productivity,” reinforcing plans to fast-track the development, Eni announced on Thursday.

Located in the Ganal PSC in Indonesia’s Kutei Basin, the Geliga-1 well flowed at rates of up to 1.7 mcm (60 mcf) per day during testing, with limited pressure drawdown. Based on the results, Eni estimates the well could produce about 5.7 mcm (200 mcf) per day of gas and about 10,000 boepd of condensate.

The company has calculated that the discovery holds about 142 bcm (5 tcf) of gas and 300 million barrels of condensate in place. Eni is preparing to submit a development plan to the Government of Indonesia in the coming weeks and studying additional liquefaction capacity at the Bontang plant that could enable the reactivation of up to two LNG trains currently out of service.

Eni operates the Ganal PSC with an 82% interest, while Sinopec holds the remaining 18%. The PSC is part of a portfolio of 19 blocks planned for transfer to Searah, a company jointly controlled by Eni and Petronas, announced in November 2025.

Eni has been active in Indonesia since 2001, with a focus on offshore gas in East Kalimantan, including the Jangkrik and Merakes developments. Its Merakes and Jangkrik assets are connected to regional LNG supply infrastructure, with Jangkrik gas supplying the Bontang liquefaction plant.
