In a regulatory filing, mining baron Anil Agarwal's company which had recently merged oil explorer Cairn India with itself, said it has notified the oil ministry and the upstream regulator Directorate General of Hydrocarbons (DGH) about the discovery in well A3-2 in block KG-OSN-2009/3.
Vedanta holds 100 per cent participating interest in the block.
"A3-2 is the first exploration well drilled within the KG-OSN-2009/3 block," it said. "Multiple reservoir zones were encountered in the Mesozoic rift formation between the depths of 3351-3944 meters with indications of hydrocarbon during drilling and formation evaluations."
One zone flowed gas to surface during well testing.
"Further appraisal will be required to assess the potential commerciality of this Mesozoic rift discovery," the firm added.
