Eni SPA has successfully drilled and tested the Maha 2 appraisal well in West Ganal block offshore East Kalimantan, Indonesia. The field is 16 km southeast of Jangkrik floating production unit, operated by Eni.
The well, drilled to a depth of 2,970 m in 1,115-m water depth, encountered 43 m of gas-bearing net sands with excellent reservoir characteristics in levels of Pliocene age, Eni said. The production test, limited by surface infrastructure, recorded gas flows of 34 MMscfd.
Eni plans to drill two other appraisal wells for Maha field. It will use test results and reservoir cores to prepare a field development plan, most likely using subsea completion and a tie-in to Jangkrik.
The company operates West Ganal through its affiliate Eni West Ganal Ltd. (40%), while Neptune West Ganal BV and PT Pertamina Hulu West Ganal hold 30% stakes each.
Eni earlier this year began production from its Merakes project offshore East Kalimantan (OGJ Online, Apr. 26, 2021). The company produces about 80,000 boe/d in Indonesia.
