Statoil has been given consent by Norway’s offshore watchdog for use of mobile drilling facilities in its Johan Sverdrup, Sigyn and Visund fields.
The Island Wellserver and Island Frontier will be used in the Johan Sverdrup and Sigyn which are both in the North Sea and operated by Statoil.
Production on the former, which lies about 140 miles west of Stavanger, is due to begin in 2019.
Both facilities are owned by Ulsteinvik-based Island offshore with drilling consent from the Petroleum Safety Authority applying from next month until March 2020.
In addition, Statoil has been given permission to use the Deepsea Atlantic drilling facility in the Visund field, which lies 22 kilometres north-east of the Gullfaks field in the Tampen area.
Drilling is set to begin early next month and is expected to last for 165 days.
Deepsea Atlantic is operated by Odfjell drilling AS.
