Eni makes ‘significant’ gas discovery offshore Indonesia

Eni has made a gas discovery in the Muara Bakau PSC in Kutei basin, about 50 km off the coast of East Kalimantan in Indonesia. The discovery lies near existing infrastructure, adjacent to existing discoveries, and options for a fast-track development are being studied.

The find, which the operator called 'significant,' was made through the Konta-1 exploration well, drilled to a depth of 4,575 m in 570 m of water. It encountered gas in four separate sandstone reservoirs of Miocene age with good petrophysical properties.

A well production test (DST), performed in one of the reservoirs, flowed up to 31 MMscfd of gas and about 700 b/d of condensate.

Based on the DST results, the well has an estimated potential for a multi-pool gas rate of up to 80 MMscfd of gas and about 1,600 b/d of condensate. Preliminary estimates indicate a discovered volume of 600 bcf of gas in place in the four reservoirs hit by the well trajectory.

Additional reservoir segments in the Konta prospect area, not penetrated by the well, but with similar gas signature, may bring the overall volumes beyond 1 tcf gas initially in place, Eni said.

Eni said the discovery also provides additional confidence in continuing the planned exploration campaign in the basin, in which the company expects to drill four additional wells in 2026.

Eni is operator of the Muara Bakau PSC (88.334%). Saka Energi holds the remaining 11.666%.
