Eni’s Geliga‑1 DST confirms ~200 MMSCFD gas and 10,000 bpd condensate offshore Indonesia
- Eni's Geliga-1 DST flowed up to 60 MMSCFD (rig-constrained) and indicates a sustainable well rate of ~200 MMSCFD and ~10,000 bpd condensate.
- The well penetrated a substantial Miocene column in ~2,000 m water to 5,100 m total depth with preliminary in-place estimates of ~5 Tcf gas and 300 million barrels condensate.
- Adjacent Gula (≈2 Tcf gas, 75 million barrels condensate) could enable combined incremental production of about 1,000 MMSCFD gas and 80,000 bpd condensate.
- A Plan of Development will be submitted in the coming weeks and studies are assessing reactivation of up to two Bontang LNG trains to provide additional liquefaction capacity.
Test results
A Drill Stem Test on Geliga‑1 flowed up to 60 MMSCFD (rig‑constrained) with minimal pressure drawdown, indicating excellent deliverability and an estimated sustainable well rate of ~200 MMSCFD and ~10,000 bpd condensate.
Reservoir and location
Geliga‑1 sits in the Ganal Block of the Kutei Basin ~70 km offshore East Kalimantan, drilled in ~2,000 m water to ~5,100 m total depth, intersecting a substantial Miocene column with strong petrophysical properties and preliminary in‑place estimates of ~5 Tcf gas and 300 million barrels of condensate.
Adjacent resources and upside
The nearby undeveloped Gula discovery (~2 Tcf gas, 75 million barrels condensate) and Geliga together could support combined incremental production on the order of 1,000 MMSCFD of gas and 80,000 bpd of condensate.
Development and infrastructure
A Plan of Development is being prepared for submission in the coming weeks to fast‑track a third production hub in the Kutei Basin by leveraging the North Hub development concept; parallel studies are assessing additional liquefaction at Bontang, potentially reactivating up to two idle LNG trains.
Ownership and transaction note
The Ganal PSC is operated by Eni (82%) with Sinopec (18%) and is included in a portfolio planned for transfer to Searah (Eni–PETRONAS JV), with the transaction closing confirmed for Q2 2026 and a contemplated third‑party sale of a 10% stake expected in 2026.
