Statoil and its PL265 partners has completed drilling of an appraisal well in the western part of the Johan Sverdrup field in the North Sea.

The well, which was drilled using the Ocean Vanguard rig, encountered a gross 82m oil column in Jurassic sandstones.

During a production test, the well flowed at almost 6,000 barrels per day in the upper part of the reservoir.

Sidetrack 16/2-17B, which did not encounter Jurassic reservoir, was tested potential in the Cliffhanger South area west of the current outline of the Johan Sverdrup field.

It was also tested as a secondary target in the granitic basement of the Utsira High.

The core samples from the Sidetrack 16/2-17B section contained oil shows that were confirmed to be non-producible and reduce the possibility for upside potential in the basement section in the Johan Sverdrup field.

The Ciffhanger South was defined as a separate target in PL265.

Johan Sverdrup field development senior vice president, Øivind Reinertsen, said: "Well results confirm the extent of the reservoir along the western margin of the field and excellent reservoir characteristics we have seen elsewhere in the Johan Sverdrup field."

"This is important input for the further planning of the field development," Reinertsen added.

Statoil Norway exploration senior vice president Gro Haatvedt, said: "Statoil still sees potential in the Cliffhanger North area based on seismic data and our geological models, and will test it with a dedicated well later this summer."
