Cairn Energy: SNE-5 Appraisal Well Hits Oil, Gas
Cairn Energy plc announced Tuesday that multiple samples of oil and gas have been recovered at the SNE-5 appraisal well offshore Senegal.
The samples were recovered during wireline logging and drill stem tests, with analysis indicating oil of similar quality to previous wells in the area. Two drill stem tests were conducted within upper reservoir units, which were said to be in line with expectations.
DST 1a flowed from a 59-foot interval at a maximum rate of around 4,500 barrels of oil per day (bopd) on a 60/64” choke. For DST 1b an additional 27-foot zone was added and the well flowed at a maximum rate of 4,200 bopd.
SNE-5 has now been plugged and abandoned and the drilling ship used for the well is moving location to commence operations on the Vega-Regulus (VR-1) well, around 3 miles west of the SNE-1 discovery. VR-1 has two objectives; an Aptian exploration target and an appraisal objective in the SNE field.
The well will target the Vega-Regulus exploration prospect in the Aptian carbonates underlying the SNE field which has potential gross mean consolidated prospective resource of more than 100 million barrels, Cairn said in a company statement.
In addition, the well will provide further appraisal on the SNE field targeting potential incremental resources. The results will help narrow the range of SNE field volumes and also allow the joint venture time to fully integrate the results of SNE-5 prior to moving to appraisal well SNE-6 to complete the planned interference test.
