Nexen Exploration Norge AS, operator of production license 419, is in the process of completing the drilling of wildcat well 35/9-5. The well is located about six kilometers southwest of the Gjøa field in the North Sea.

The objective of the well was to prove petroleum in the Agat formation in Lower Cretaceous reservoir rocks. The well did not encounter the reservoir rocks as expected in the Lower Cretaceous. However, non-mobile petroleum was encountered in reservoir rock with little thickness and poor reservoir quality deeper in the Cretaceous. Data acquisition and sampling have been carried out. The well is classified as a dry well.

The well is the first exploration well in production license 419, awarded in APA2006. The well was drilled to a vertical depth of 3513 meters below the sea surface and was terminated in the Middle Jurassic. The water depth at the site is 365 meters. The well will now be permanently plugged and abandoned.

Well 35/9-5 was drilled by the West Alpha semisub, which will now proceed to production license 433 in the Norwegian Sea to drill wildcat well 6506/9-2S where Centrica Resources Norge AS is the operator.

The licensees in production license 419 are:

  • Nexen Exploration Norway AS (op) 45%
  • PGNiG Norway AS 25%
  • OMV Norge AS 30%
