BG Group has drilled two dry wells in production license 373S in the Norwegian North Sea, the Norwegian Petroleum Directorate reported Monday.
Wildcat wells 34/3-4S and 34/3-4A were drilled about three miles east of the Knarr field in the northern part of the North Sea. The purpose of well 34/3-4S was to investigate a large channel system in reservoir rocks in the Pleistocene layer. The well found an 820-foot thick channel system, about 164 feet of which were of very good reservoir quality. Traces of gas were encountered in two thin sandstone layers.
The drilling of well 34/3-4A aimed to prove petroleum in lower Jurassic reservoir rocks (the Cook formation). This found approximately 360 feet of the Cook formation, 174 feet of which was sandstone of good reservoir quality and traces of gas.
However, after data collection and sampling were performed on both wells they were classified as dry. The wells will now be permanently plugged and abandoned.
The wells were drilled by the Transocean Searcher (mid-water semisub) drilling facility, which will now move on to drilled wildcat well 34/3-5S on the same production license.
