Eni has drilled a successful appraisal to the Maha gas field in the mature Mahakam Delta within the Kutei Basin, offshore Indonesia, 20 years after the discovery well. Eni drilled the well with partners Pertamina and Neptune Energy on the West Ganal Block. Maha-2 was drilled in April and May 2021 in 1,115m of water, to a depth of 2,970m and recovered gas from deltaic clastics. The well tested 34 MMcfgd from 43m of net reservoir in Pliocene sands, and the development plan may utilize a subsea tie-back to the nearby Jangkrik FPU.

Neptune Energy, backed by private equity global players Carlyle Group, CVC and CIC, entered this basin in 2019 as part of a multi-asset deal with Eni. Eni have been exploring and developing gas in the basin for decades, and the opportunity to revisit some of the early discoveries in the Ganal region has proven successful so far, with Maha expected to hold up to 600 Bcf gas. This West Canal Block was awarded to Eni, Neptune and Pertamina as part of the 2019 Indonesia bid round and includes a commitment to a further 3 wells.
