Eni Discovers Gas Giant off Indonesia

Total structure discovered could hold as much as 5 Tcf of gas in place.

Eni has struck significant gas reserves with its Geng North-1 exploration well drilled in North Ganal PSC, about 85 km off the coast of East Kalimantan in Indonesia. Preliminary estimates indicate a total structure discovered volume of 5 TcF of gas in place with a content of condensate estimated up to 400 million bbl. The acquired data will allow study of the options for a fast-track development.

Geng North-1 was drilled to a depth of 5025 m in 1947-m water depth, encountered a gas column about 50-m thick in a Miocene sandstone reservoir with excellent petrophysical properties. A well production test was successfully performed for a full assessment of the gas discovery and although limited by the test facilities, it has allowed a well capacity estimate of up to 80–100 MMcf/D and up to 6,000 B/D of condensate.

Given its location and significant size, the discovery has the potential to contribute substantially to the creation of a new production hub in the Northern part of the Kutei Basin to be connected to the Bontang LNG facilities on the coast of East Kalimantan.

In addition to Geng North, more than 5 Tcf of gas in place are estimated to be present in undeveloped discoveries within the area of interest, while ongoing studies focus on a significant multi-Tcf exploration potential.

Eni North Ganal Ltd. holds a 50.22% participating interest and operates the PSC, with Neptune Energy North Ganal BV and Agra Energi I Pte Ltd. as partners, holding the remaining 38.04% and 11.74%, respectively.
