Eni has successfully drilled and tested the Maha 2 appraisal well, located in the West Ganal block offshore Kalimantan, in Indonesia. The field is located 16 km south-east of the Jangkrik FPU, operated by Eni.

The well has been drilled to a depth of 2970 m in 1115 m water depth and encountered 43 m of gas bearing net sands with excellent reservoir characteristics in levels of Pliocene Age.

The production test, which was limited by surface facilities, recorded gas deliverability of the reservoir flowing at 34 million ft3/d. Through the test and the coring of the reservoir important data has been collected to perform all the studies required for the preparation of a field development plan for the Maha field, where two other appraisal wells are planned to be drilled. The development plan will most likely foresee a subsea completion and a tie-in to the Jangkrik FPU.

Eni is the operator of the West Ganal block through its affiliate Eni West Ganal Ltd., holding a 40% participating interest while Neptune West Ganal B.V. and P.T. Pertamina Hulu West Ganal hold a 30% stake each.

Neptune Energy’s Managing Director for Indonesia, Eko Lumadyo, said: “Maha is an exciting development for Neptune Energy, and this latest milestone brings us a step closer to bringing the discovery into production via existing infrastructure, supporting both Indonesia’s growing domestic energy demand and its burgeoning export market.

“Indonesia is a strategically important part of Neptune’s production portfolio and our progress at Maha 2 follows commencement of production from Merakes earlier this year, and ahead of further planned activities in other discoveries and prospects. These projects are an example of the exciting growth opportunities that Indonesia offers and we look forward to building upon our recent successes in the country through our partnership with Eni and Pertamina.”
