Norway's Statoil has made a small discovery near the Gina Krog development project, according to the Norwegian Petroleum Directorate and pratner Det norske.
Wildcat well 15/6-13 and appraisal wells 15/6-13 A and 15/6-13 B were drilled using the Songa Trym semisubmersible drilling rig (pictured) in 140m water depth about 250km west of Stavanger and directly northeast of the Gina Krog field.
The wells encountered gas and oil in both the Hugin and Sleipner formations, says Det norske. The total gas column in the Hugin formation is estimated to be about 150m and the oil column is evaluated to be about 150m, resulting in a total hydrocarbon column height of about 300m, with good reservoir properties, says Det norske.
Det norske says initial analysis indicates the wells have proven in the range of 6-13 MMboe recoverable. Additional volumes in the Sleipner formation will be further evaluated and further studies undertaken to evaluate if the discovery can be produced as part of a future area development solution.
Wells 15/6-13, 15/6-13 A and 15/6-13 B were drilled to a measured depth of 3577m, 3925m and 3773m, respectively, and vertical depths of 3552m, 3716m and 3447m below the sea surface. They were all terminated in the Skagerrak formation in the Upper Triassic. The wells have been permanently plugged and abandoned.
