Natural resources company Vedanta has made an oil discovery in the second exploratory well H2, located in KG-OSN-2009/3 block in the Krishna-Godavari Basin offshore India.
The company owns 100% participating interest in the KG-OSN-2009/3 block, which partly covers offshore areas of the Prakasam and Guntur districts.
At the time of drilling and down hole logging, Vedanta encountered multiple reservoir zones in the H2 within the Mesozoic sequence between the depths of 3310m and 4026m with hydrocarbon indications.
The company tested the zone from 3403m to 3431m through a drill stem test and flowed oil to the surface. Vedanta is planning further appraisal of the well to establish the size and commerciality of the latest oil discovery in the Mesozoic sequence.
Vedanta drilled the initial exploration well A3-2 in the block in September 2018, where gas was discovered. Following the drilling of A3-2 well, the company encountered multiple reservoir zones in the Mesozoic rift formation between the depths of 3351m and 3944m MDBRT with indications of hydrocarbon during drilling and formation evaluations.
Evaluations are ongoing to finalise the next programme, based on the results of the first well A3-2 and the second well H2.
Vedanta’s subsidiary Cairn India secured approval from the Expert Appraisal Committee (EAC) in January 2017 to carry out drilling works of 64 exploratory and appraisal wells in the KG-OSN-2009/3 block. At the time, the committee set a few conditions along with other environmental conditions relevant to the project proposal.
