A significant gas condensate discovery off the east coast of India has been revealed by Reliance Industries Limited (RIL) and BP.
The D-56 find in the Cauvery basin is located in deepwater block CY-DWN-2001/2 (CYD5), approximately 62 km off- shore, and is the second gas discovery in the block. RIL is the operator with 70% equity, with BP holding the remainder. Well CYIIID5-S1 was drilled in a water depth of 1,743 m (5,719 ft) to a total depth of 5,731 m (18,803 ft), with the primary objective of exploring Mesozoic-aged reservoirs.
Preliminary evaluation of well data and fluid samples indicated the presence of gas condensate in the reservoir interval with a gross column of 143 m (469 ft). The well reached its total depth in early August and RIL has conducted a drill stem test to evaluate its potential.
The well, which had an initial reservoir pressure of 8,000 psi, flowed gas at a rate of 35.2 MMcf/d with condensate flowing at a rate of 413 b/d through a 52/64-inch choke during the DST.
Cairn Oil & Gas will drill about 300 development/injection wells and construct 205 well pads to increase production from the Barmer fields.
Drillers cut nine oil rigs in the week to March 22, bringing the total count down to 824, the lowest since April 2018, Baker Hughes, a GE company (NYSE: BHGE), said in its weekly report.
