On 29th March, Cairn announced the success of its first appraisal well at the Mangala oilfield in Rajasthan. Mangala-1ST was drilled from the N-B-1 discovery well surface location and deviated 400 metres away in an up-dip direction, reveals Cairn.

Cairn said an open hole drill stem test was conducted at the appraisal well and that the open hole tests revealed the following stabilised rates: Zone 2 tested at 1,250 barrels of oil per day of 30 degrees API oil on a 56/64 inch choke. Zone 1 tested at 2,800 b/d of 27 degrees API oil on a 2-inch choke.

Three more appraisal wells will be drilled from new locations.
