Minor gas/condensate discovery – 6406/6-4 S

Edison Norge AS, partner of production licence 510, informs that drilling of wildcat well 6406/6-4 S  is about to be completed. The well was drilled about 20 kilometres southwest of the Tyrihans field in the Norwegian Sea.

The primary exploration target for the well was to test reservoir properties and hydrocarbon potential in of the Middle Jurassic reservoir rocks (the Garn formation). The secondary exploration target was Middle and Lower Jurassic reservoir rocks (Ile and Tilje formations).

The well encountered a 25 m hydrocarbon column in the Garn formation, with 102 m thick sandstone with good reservoir quality. The well also encountered 67 m and 45 m thick sandstones with good reservoir quality in the Ile and Tofte formations, respectively, but they were water-filled. The well drilled 50 m into the Tilje formation, this was also water-filled. The preliminary estimate of the size of the discovery - done by operator- is between 1.5 and 3 million Sm3 of recoverable oil equivalents. Edison Norge AS will evaluate this result to perform an assessment of the additional hydrocarbon prospectivity in the license.

The well was not formation-tested, but data acquisition and sampling have been carried out.

This is the first exploration well in production licence 510. The licence was awarded in APA 2009.

Well 6406/6-4 S was drilled to a measured and vertical depth of 4524 m and 4484 m below the sea surface, respectively, and was terminated in the Tilje formation in the Lower Jurassic.

Water depth at the site is 261 m. The well will now be permanently plugged and abandoned.

Well 6406/6-4 S was drilled by the Leiv Eiriksson drilling facility.

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