Chevron North Sea Limited announced today that it has awarded a new £150 million contract to Dolphin Drilling Limited, a subsidiary of Fred. Olsen Energy ASA, for a 20 month multi-well drilling and completion program across several of Chevron’s operations in the U.K. sector of the North Sea.

The contract is to provide drilling and completion operations using the semi-submersible rig, the Blackford Dolphin, and includes a rig refurbishment to upgrade the unit for North Sea activity work.

The drilling program is expected to commence in 2015 for an initial period of 572 days. Chevron has an option to extend the drilling program for a further one to two years.
