Oil and Natural Gas Corporation (ONGC) has made a gas discovery in the Krishna Godavari Basin onshore eastern India with its Vygreswram Southwest-1 exploration well drilled in PEL Block-1B of KG (Onland), KG-PG Basin.
ONGC said that it has notified India's Directorate General of Hydrocarbons (DGH) of the gas find, which proved a 30-meter gas column on testing and produced gas at a consistent flowrate of approximately 2.6 million cf/d of natural gas and 18.8 million b/d of condensate. It said that the well was drilled to a total depth of 4,600 meters (15,093 ft) to explore the syn-rift Cretaceous sequence.
The Indian national oil company said that this new discovery has further established the prospectivity of Raghavapuram play towards the southwest of VG-1 in the north Pasarlapudi area.
"Our recent exploratory successes are the result of a two pronged strategy of targeting deeper as well as shallower targets in operational areas in different basins. This strategy has given rich dividends in the form of discoveries made," ONGC said, noting that exploration efforts have resulted into significant finds at Vygreswaram, South Mahadevpattanam, and Penugonda in the KG onshore area, adding 18.50 million tons of oil and oil equivalent gas reserves. Similar efforts in Assam and Assam Arakan Basin have resulted into discoveries at Disangmukh and Panidihing in Tura Formation in the past. In the Western onshore basin, Charada, Halisa, and Gamij finds have resulted in accretion of 23 million tons of oil and oil equivalent gas reserves.
In addition, ONGC today reported it has spudded a first shale gas well, RNSG-1, in Ichapur village near Durgapur in West Bengal.
