This well, which is the fifth exploration well on D3, was spud using the Transocean rig the Deepwater Expedition in a water depth of 1,653mt. The target depth of the well, which aims to explore the hydrocarbon potential of Mio-Pliocene sands, is 3,514mt MDRT.

Three consecutive gas discoveries have been made on D3: Dhirubhai 39, 41 and 44. Due to a limited window of rig availability, the fourth well, G1, was pre-drilled to the 20″ casing point and will be re-entered to drill to the target depth in the future, the company said.

The D3 licence is located in the Krishna Godavari basin on the east coast of India and covers an area of approximately 3,288sqkm. The licence terms require a minimum of six exploration wells to be drilled within the first exploration phase. The company holds a 10% participating interest in the block, with Reliance Industries holding 90% as operator.
