The Mangala, Bhagyam and Aishwariya (MBA) are the three largest finds in Rajasthan. The oil and gas fields in the Rajasthan Block constitutes Cairn India's key assets in Rajasthan. The Mangala field- considered to be the largest onshore hydrocarbon find in India in the last two decades - was discovered in January 2004. This was followed by the discovery of Aishwariya and Bhagyam fields. To date, 31 discoveries have been made in the Rajasthan block. The Production Sharing Contract (PSC) for the project was signed on 15 May, 1995. In 1997, Cairn acquired an interest in the block. In 2002, Cairn acquired 100% of the exploration interest and assumed the role of operator.
