The Cairn Oil & Gas, India’s largest private oil and gas exploration and production company, has signed a contract with Baker Hughes, an energy technology company, to harness geothermal energy from its repurposed oil and gas wells in Rajasthan. On successful execution, the contract will help Cairn Oil & Gas co-produce up to 2.4 MW of electricity along with oil and gas and offset 17,000 tons of greenhouse gas per annum. This contract follows Cairn Oil & Gas’ recently announced ESG roadmap where it is committed to becoming a net-zero company by 2050, a spokesperson said here on Friday.
