Cairn Oil & Gas, a Vedanta Group company, has drawn up plans to invest $700 million to boost drilling infrastructure at its around 100 exploratory wells in the country, including in the pilot project for shale oil and gas in Rajasthan’s Barmer region.
The investments are part of Cairn’s $4-5 billion capex planned over the next three-four years, Prachur Sah, deputy CEO, told FE.
The company has hired Halliburton and Schlumberger to prepare a detailed report on estimates of in-place shale reserves and how production activities could be taken forward. “Going by initial estimates, there are in-place shale reserves of around 3-4 billion barrels (in Barmer region). Although the entire reserves are not recoverable, even if we take typical industry recovery of 10%, it will be 300-400 million barrels of hydrocarbon,” added Sah.
Cairn’s average daily production was at 159,000 barrels of oil equivalent during the three months that ended December 31, 2021, and it plans to triple this in the next three years with the planned investments.
The pilot for shale is expected to begin by June. Thereafter, it will take at least 3-4 months for drilling and to understand if the activity is commercially viable. “By the end of 2022, we will get a fair idea of the reserves. The investments could increase with successful discoveries,” Sah said.
