Well B12C-2(B-12C-A), drilled in shallow water on the B-12 (Dahanu) prospect in the Western Offshore basin, tested gas at 229,297 cm/d from the Upper Oligocene Daman formation, and 383 b/d of condensate.
Another well, B157N-1(B-157N-A), in the shallow-water Bombay Offshore area of the same basin flowed 640 b/d of oil and 31,050 cm/d of gas from a clastic interval in the Panna formation.
The result has broadened the scope for future exploration in the area north of the B157 concession, ONGC said.
In the KG shallow water offshore KG-PG basin off Andhra Pradesh state, well GS-71-1(GS-71-AA) on the GS-15/23 PML block produced 7.8 MMcmoe of oil and gas through a 12/64-in. choke; oil and gas in the Vadaparu formation via a 16/64-in. choke; and condensate and gas from the Ravva formation through a 16/64-in. choke.
However, ONGC has yet to determine the commerciality of this find.
