Vedanta-owned Cairn Oil & Gas is set to embark on a $1.1 billion enhanced oil recovery campaign at its Block RJ-ON-90/1 onshore Rajasthan, which is likely to lead to 100,000 barrels per day of incremental oil production in 18 months.

Cairn has submitted to the Indian government an EOR field development plan covering the use of Alkaline Surfactant Polymer (ASP) and is hoping to soon secure approval.
