Colter will be a success27 Jan 2019 07:55
Colter was discovered in 1986 by the 98/11-3 well, which encountered a 10.5m oil column in the Sherwood Sandstone reservoir, the same play that has proven to be so productive at Wytch Farm. Based on the results of pre-stack depth migration reprocessing of 3D seismic data, significant potential lies updip of 98/11-3, which was drilled to the south of the Colter structure. The new Well will target this potential. In a Competent Person's Report, ERCE assigned gross unrisked mid-case oil contingent resources of 4mmbbls to the section proven up by the 98/11-3 well, and gross unrisked mean-case prospective resources of 15mmbbls to the rest of the structure extending to the west. As well as the Sherwood Sandstone target that is the main reservoir from which Wytch Farm produces, there is also potential in the shallower Jurassic Bridport Sandstone which is in production at Wareham
