Cairn Energy Announces Discovery Offshore India

Cairn has made a second gas discovery on Block KG-DWN-98/2 offshore Andhra Pradesh in Eastern India with its exploration well DWN-R-1. The well is located approximately 17 miles southwest of the N-1 gas discovery, which was announced in March 2001. DWN-R-1 reached a total depth of 7,644 feet and encountered several gas pay zones below 6,135 feet. Two drill stem tests were carried out and flowed gas at a combined stabilized rate of 80 million standard cubic feet of gas per day. The flow rates were constrained by down hole tubing and surface test equipment limitations. Initial reserve estimates are in the range of 0.75 to 1 trillion cubic feet of dry gas. The R-1 discovery will be appraised by a second well to be drilled later this year. Marine Drilling’s semisubmersible, Marine 500 will now move to Prospect 'P', approximately 41 miles northwest of DWN-R-1.
