Det Norske Commences Drilling Ops at North Sea's Freke for ExxonMobil

Det norske spudded the North Sea Freke prospect in PL 029B on February 6, 2009. Det norske is drilling well 15/6-10 on behalf of ExxonMobil.

ExxonMobil is the license operator with an ownership interest of 50%. StatoilHydro holds 50%, while Det norske will take a 20% interest from ExxonMobil when drilling operations are completed.

The Slepner B platform on the Sleipner Field and Petrojarl 1 on the Glitne Field are the nearest installations to the Freke prospect. These installations are located 30 and 11 kilometers from Freke, respectively. The distance from shore is about 200 kilometers and the water depth at Freke is 112 meters.

Freke is located in the South Viking Graben and holds a volume potential of 90 million BOE (P 50). The structure has four-way closure delimited by a north-south trending horst. The primary reservoir is expected to be middle Jurassic Hugin Formation, with the underlying Sleipner Formation, constituting a secondary target. Expected hydrocarbons are light oil, possibly with a gas cap.

The exploration well is planned as a vertical well with a total depth of 3695 meter with no drillstem test.

Det norske will utilize the third generation Aker H-3 semisubmersible drilling rig Bredford Dolphin for the operation. Rig owner is Fred Olsen ASA. It is operated by Dolphin.
