Explanation
Cairn Energy, now known as Cairn Oil and Gas and part of Vedanta Limited, is the company responsible for the major oil discoveries in the Barmer Sanchore basin. The most significant discovery in this region is the Mangala field, which started commercial production in 2009. While ONGC is a joint venture partner in the project, Cairn Energy acted as the operator and lead explorer that established the basin as a major oil producing hub in India. Individual companies like Unocal and Reliance Energy Ventures were not the primary entities associated with the commercial production in this specific Rajasthan basin.
