Det norske oljeselskap ASA is about to complete drilling operations on well 7222/11-2 on the Langlitinden prospect in production licence 659 in the Barents sea.
The well (7222/11-2) encountered an oil-bearing channel sand of Triassic age. The primary objective of well 7222/11-2 was to prove hydrocarbons in the Kobbe Formation reservoir (Triassic) and notably to prove good flow properties in the same reservoir. The well, located approximately 165 kilometers northwest of Hammerfest, encountered oil in a channel sand, which also was the main target for the well.
Extensive data sampling, including cores, wireline logs and fluid samples have been performed. Movable hydrocarbons were proved in the main target for the well, but mini-DST proved poor reservoir properties.
“The partnership in production licence 659 will evaluate the results carefully with respect to the remaining prospectivity of the licence. Based on preliminary analysis, Det norske is of the opinion that the volumes proven in this well, as of today, are insufficient to justify a field development,” Det norske said in a press release.
The well was drilled to a total depth of 2,878 metres below sea level, using the Transocean Barents semi-submersible drilling rig. The water depth is 338 metres. The well will now be permanently plugged and abandoned.
The licensees in PL659 are Det norske oljeselskap ASA (20 percent), Lundin (20 percent), Tullow (15 percent), Rocksource (5 percent), Petoro (30 percent) and Atlantic (10 percent)*.
