Cairn Completes Saraswati-2 Appraisal Well

The Saraswati field appraisal is underway and commenced with a down dip appraisal well, Saraswati-2, which was completed in early May. The Saraswati-1 discovery well established an 'Oil Down To' in an upper and a lower reservoir unit. Saraswati-2 was drilled two kilometers to the southeast and was designed to establish an oil water contact.

Saraswati-2 encountered oil and no water in the upper reservoir and has confirmed an oil column of approximately 300 meters. The reservoir has relatively low permeability at this location and only small quantities of oil flowed to surface on test. The lower reservoir unit in Saraswati-2 encountered a thickening wedge of sands not seen in Saraswati-1. Although the sands in this interval were water bearing, they had a net thickness of 190 meters of permeable reservoirs. This is the first time such thick, high quality sands have been found in the basin and efforts are underway to target this additional unit in the future exploration drilling campaign.

The rig is currently being moved five kilometers to the northwest to drill a second appraisal well on Saraswati in a separate fault compartment. Thereafter the rig will be moved to another exploration well location while additional drilling rigs are being sought for other exploration and appraisal drilling.

The Saraswati discovery is located on Block RJ-ON-90/1 in western India. Cairn is the operator has holds a 100% interest.
