The Steam Oil Production Company has entered into a sale and purchase agreement with EnQuest Heather Ltd to acquire a 100% interest in Licence P1996, made up of blocks 28/2b and 28/3b, which cover the Elke and Narwhal discoveries. The transfer of the interest is subject to approval by the Oil & Gas Authority (OGA), which would also require OGA's approval of The Steam Oil Production Company Ltd as licence operator.
The Narwhal field was discovered by well 28/2-1, which was drilled by Arco in 1993. The well encountered heavy oil in an Eocene Tay sandstone and a sample of 14° API oil was recovered, the viscosity measured for the Narwhal oil was in excess of 2,000 cP. This interval was also logged and cored. The Narwhal field has an estimated oil in place of around 41 mmbbls.
