India’s Oil and Natural Gas Corporation (ONGC) has announced three oil and gas discoveries, India’s Economic Times has reported.
The company struck oil and gas in India’s Matar region in the Vadodara district, oil in the Cambay basin and gas in the Krishna-Godavari (KG) basin. Natural gas has been discovered in the IE block in the KG basin.
ONGC chairman and managing director RS Sharma said the “discoveries need to be appraised and the commerciality of these discoveries are yet to be established.”
The IE block is located 6km off Yanam coast in the KG basin. This is the second discovery made by the company in the KG basin. In December 2006, the KG-DWN-98/2-UD-1 well in the ultra-deep waters of KG offshore found first gas in a water depth of 2,841m.
The second discovery was made in the Charada-3 exploratory well, which was drilled in January. Two zones comprising the Deccan Trap and another in the Olpad formation showed occurrences of heavy and viscous oil on preliminary testing, the company said.
After discovering oil in the Matar-11 well, ONGC achieved success in the Matar region of the Vadodara district. In March 2009, the Matar-11 well was drilled and flowed oil and gas from two intervals.
The production well is now flowing oil at a rate of 40m3/d from the second interval. The well falls in a block which was earlier awarded to Niko Resources and Gujarat State Petroleum Corporation, which were unsuccessful in their efforts to discover hydrocarbons.
