In 2006, the high-quality reserves of natural gas were discovered in the Shahgarh sub-basin of Jaisalmer district in Rajasthan.
The gas was discovered in the exploration block of Focus Energy, an independent oil and gas exploration and development company.
Focus Energy struck gas in its onshore blocks RJ-ON/6 in well SGL-l. The discovery was made in cretaceous reservoir sandstones at a depth of 3,100 meters.
The well flowed 15 mmscf/d (million standard cubic feet per day) of almost pure methane gas through a 48/64 choke.
