Reliance Industries Limited (RIL) and BP made a new gas condensate discovery off the east coast of India in the Cauvery Basin.
The discovery, in the deepwater block CY-DWN-2001/2 (CYD5), is 39 miles (62 km) from the coast in the Cauvery Basin and is the second gas discovery in the block. RIL is the operator with 70% equity, and BP has a 30% share. Well CYIII-D5-S1 was drilled in a water depth of 5,719 ft (1,743 meters), to a total depth of 18,802 ft (5,731 meters), with the primary objective of exploring Mesozoic-aged reservoirs.
Preliminary evaluation of well data and fluid samples indicated presence of gas condensate in the reservoir interval with a gross column of 469 ft (143 meters). The well reached its total depth in early August, and RIL, as operator, has conducted a drill stem test (DST) to evaluate the potential of the discovery.
The well, which had the initial reservoir pressure of 8,000 psi flowed gas at the rate of 35.2 million standard cu ft/day with condensate at the rate of 413 bbls/day through 52/64-in. choke during the DST. Well flow rates during such tests are limited by the rig and well test equipment configuration.
