Statoil Petroleum has completed drilling of exploration well 34/8-16 S located on the east flank of the Visund field in the northern part of the Norwegian North Sea.
Visund is an oil and gas field in blocks 34/8 and 34/7 and is located 22km north-east of the Gullfaks field in the Tampen area.
The drilling, which was performed using the Songa Trym drilling facility, was aimed at discovering gas or gas condensate in the Middle Triassic.
Drilled to a vertical and measured depth of 3875 and 3830m below sea level, respectively, the well was terminated in the Hegre group in the Triassic.
The secondary exploration target of Statoil was to investigate additional resources in Lower to Middle Jurassic reservoir rocks as well as the Upper Triassic reservoir rocks.
The well 34/8-16 S, which is the 26th exploration well drilled in production licence 120, encountered an oil/gas/condensate column of about 85m in the Lunde formation.
According to preliminary estimates, the size of the discovery would range between 0.4 and 1.1 million Sm³ of recoverable oil equivalents.
The company carried out comprehensive data collection and sampling on the well, which was not formation tested.
The licensees will consider further development of the discovery alongside other potential additional resources.
Statoil now plans to permanently plug and abandon the well.
