Cairn Oil & Gas, a unit of Vedanta Limited, has commenced test production from its Hazarigaon field in Assam that it had won in a discovered small field bid round. The gas produced by Cairn Oil & Gas is evacuated through a main trunk pipeline, and a gas cascading system to Assam Gas Company Limited. Additionally, the gas cascading system will enable gas from Hazarigaon to be a prime contributor in fueling 100 compressed natural gas buses that will be plying in Guwahati as part of the clean energy initiative of the Government of Assam. The company plans to drill five to ten exploration wells in the next two years across the Golaghat, Jorhat and Tinsukia districts of Assam.
