Mr P Elango, Member of the Board, Cairn India said:

"Commencing production from Aishwariya field is another major milestone in the journey to unlock the full potential of world class Barmer basin. We have worked closely with all stakeholders to ensure that the project is delivered on time. The production will be gradually ramped up to 10,000 bbl/day and this will further reduce the nation's import bill.

Our gross Rajasthan development investment to date is more than INR 18,000 crores and we intend to invest over INR 6,000 crores in exploration and development activities during FY2013-14.

I would like to thank the Ministry of Petroleum and Natural Gas, Government of Rajasthan, DGH, our joint venture partner ONGC and the people of Rajasthan for their continued support."
