In its 218th Board Meeting on 27th April, 2011, while ONGC declares two new discoveries, it also presents an impressive provisional Annual result in terms of Reserve Accretion and Production.

The two notified discoveries are:

Exploratory Well Vadtal#3 in NELP Block CB-ONN-2004/2: ONGC has notified DGH on 16th March, 2011 about a significant discovery in NELP Block CB-ONN-2004/2 which was won in NELP-VII and where ONGC has 50% participating interest (GSPC-40% and Sunterra 10%). On testing of interval 1347.5 – 1315.5 m in exploratory well Vadtal#3 in Chhatral formation, it produced oil at a rate of 22.5 cubic meter per day and gas at a rate of 3758 cubic meter per day (through 6 mm bean). The oil produced is of very good quality with a gravity of 41.10 API.

Prospect Vadtal # 3 is a fault closure and this discovery has given impetus to exploration of similar fault closures towards north and into another NELP block CB-ONN-2001/1, where ONGC has already made a discovery in May’09 in the same trend.

Development Well North Kadi # 461 in Linch Extn-I PML: The other one is a pool discovered in the Linch Extn-I PML of North Kadi field of Western Onshore Basin of ONGC, which has been notified to DGH on 5th April, 2011. Development well North Kadi # 461 in Linch Extn-I PML, Western Onshore Basin, was drilled to a depth of 1600 m (as an inclined well from the cluster of exploratory well NK # 460). Testing of interval 1312.5 – 1316m flowed oil at a rate of 17 cubic meter per day (through 8 mm bean). The oil is heavy oil with 25.390 API.

It is important to note that for the first time oil flow has been established in commercial quantity in the particular Mandhali section in North Kadi and adjoining areas.
