Maersk Oil has made a non-commercial gas/condensate discovery from the Tvillingen South exploration well in PL 510 in the Norwegian Sea.
The well was spud on August 11, 2015. 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.
According to North Energy, a partner in the licence, the well encountered a hydrocarbon column of up to 30 metres in Garn Formation sandstones with good reservoir quality. The deeper reservoir targets showed high reservoir quality, but were water wet. The well was not formation tested, but data acquisition and sampling were carried out, North Energy said.
Well 6406/6-4S was drilled to a total depth of 4 484 metres in the Tilje Formation by the Leiv Eiriksson rig. Tvillingen South is located 220 km north-west of Trondheim on the Norwegian west coast and 20 km southwest of the Tyrihans field. The licence was awarded in the APA 2009 licensing round and the 6406/6-4S well was the first exploration well in PL 510.
North Energy ASA holds a 20 per cent working interest in PL 510. Maersk Oil Norge AS is the operator and holds 50 per cent and Edison Norge AS holds 30 per cent.
