Eni and its partners have completed drilling and testing of the Maha 2 appraisal well offshore Indonesia.

Located in West Ganal block offshore Kalimantan, the well has been drilled on Maha gas discovery situated 16km south-east of Eni-operated Jangkrik floating production unit (FPU).

Drilled to a depth of 2,970m, the well encountered 43m of gas-bearing net sands with ‘excellent reservoir characteristics’ in levels of Pliocene Age.

The Italian firm said that the reservoir recorded an excellent gas deliverability flowing at 34 million standard cubic feet per day (MMscfd), during the production test.

In a press statement, Eni said: “Through the test and the coring of the reservoir important data have 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 partners are considering developing the field as a sub-sea completion and a tie-in to Jangkrik FPU.

Eni expects to maximise the synergies while reducing time and costs of future subsea developments at the Maha field due to its proximity to the existing infrastructures.

Eni, through its affiliate Eni West Ganal, operates the block with 40% stake. Other partners include Neptune West Ganal and PT Pertamina Hulu West Ganal each holding 30% interest.

Neptune Energy Indonesia managing director Eko Lumadyo said: “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.”
