Wellesley is the operator for production licence 925 in the North Sea. The Petroleum Safety Authority Norway have now given the company consent to drill exploration well 35/12-6 S, for which the objective is to investigate a prospect named "Kallåsen".

The drilling site is in the north-eastern part of the North Sea, 14 km south-west of the Gjøa field and 18 km north-east of Vega Sør.

The well will have the following geographical coordinates:

  • 61° 13' 45.056'' N
  • 03° 45' 25.396'' E

Water depth at the site is 355 m.

Drilling is scheduled to begin in early May. The drilling operation is estimated to last 28 days if the well is dry and up to 71 days if hydrocarbons are found.

The well is to be drilled by Transocean Arctic, which is a semi-submersible mobile drilling facility of the Marosso 56 type, built by Mitsubishi Heavy Industries in Japan in 1987. It is classified by DNV GL and registered in the Marshall Islands.

The facility is operated by Transocean Ltd and received Acknowledgement of Compliance (AoC) from the PSA in July 2004.
