Maersk Oil Norway AS has concluded the drilling of wildcat well 6406/6-4S. The well investigated the hydrocarbon potential of the Tvillingen Sør prospect in PL510, which is located 220 km north-west of Trondheim on the Norwegian west coast and 20 km southwest of the Tyrihans field. 

The main objective of well 6406/6-4S was to test the reservoir properties and hydrocarbon potential of the Middle to Lower Jurassic sandstones on the Tvillingen Sør horst structure. 

The well encountered a hydrocarbon column of 25 metres in Garn Formation sandstones with good reservoir quality. The deeper reservoir targets showed high reservoir quality but were water wet. Extensive data acquisition and sampling were carried out from the well.  

“Maersk Oil will continue our pursuit for growth in Norway. This exploration well is a step in that journey. We will now analyse the data from the Tvillingen well and determine the next steps,” says Ebbie Haan, Chief Growth Officer in Maersk Oil.

Well 6406/6-4S S was drilled to a total depth of 4484m MDRT in the Tilje Formation by the Leiv Eiriksson rig. The well is being plugged and abandoned as a minor gas condensate discovery.

The licence was awarded in APA 2009 and this was the first exploration well in PL510.

Maersk Oil Norway is the operator and has a 50 percent working interest in PL510. The partners are Edison Norway AS with 30 percent and North Energy with 20 percent.
