The KGD6-MJ1 well was drilled in a water depth of 1,024 m (3,360 ft) – and to a TD of 4,509 m (14,793 ft) – to explore the prospectivity of a Mesozoic Synrift Clastic reservoir. It lies more than 2,000 m (6,562 ft) below the producing reservoirs in the D1-D3 gas fields.
Formation evaluation indicates a gross gas and condensate column in the well of about 155 m (509 ft) in the Mesozoic reservoirs. In the drillstem test, the well flowed 30.6 MMcf/d (866,496 cm/d) and liquid rate of 2,121 b/d with a 36/64-in. choke. The flowing bottomhole pressure of 8,461 psia suggests good flow potential.
The discovery, named “D-55,” has been notified to the government of India and the Management Committee of the block. This discovery is expected to add to the hydrocarbon resources in the KG D6 block. Appraisal is expected to get under way soon.
RIL is the operator of KG D6 with 60% equity. BP has a 30% share and NIKO the remaining 10%.
