The Petroleum Safety Authority (PSA) has given Statoil consent to use the Deepsea Atlantic mobile drilling facility for drilling and well operations at Gullfaks Sør.
The consent covers production drilling and work on existing production wells, in addition to permanent plugging and abandonment of three exploration wells.
Gullfaks Sør is located to the south of Gullfaks in the northern part of the North Sea.
It has been developed with a total of 12 subsea templates tied back to the Gullfaks A and Gullfaks C facilities.
Gullfaks Sør has been developed in two phases. The PDO for Phase 1 included production of oil and condensate from the 34/10-2 Gullfaks Sør, 34/10-17 Rimfaks and 34/10-37 Gullveig deposits. The PDO for Phase 2 was approved in June 1998 and covered production of gas from the Brent Group in the Gullfaks Sør deposit.
In 2004, the 34/10-47 Gulltopp discovery was included in Gullfaks Sør. Gulltopp is produced through an extended reach production well from Gullfaks A. A PDO for the 33/12-8 A Skinfaks discovery and Rimfaks IOR was approved in February 2005. The development included a new subsea template and a satellite well. An amended PDO for the redevelopment of Gullfaks Sør Statfjord Formation was approved in October 2012.
