OSLO, Norway – Statoil has permission from Norway’s Petroleum Safety Authority (PSA) consent to use the Cat J-type jackup Askeladden for drilling on the Gullfaks Sør field (Gullfaks satellites) in the North Sea.
The Gullfaks satellites are subsea developments at Gullfaks Sør, south of the mainGullfaks fields. To date Statoil has installed 13 subsea well templates for tiebacks of various structures in the area to the Gullfaks A and Gullfaks C facilities.
Production began at Gullfaks Sor in 1998: water depth in the area is 130-220 m (426-722 ft).
The consent covers drilling, side track drilling, completion, recompletion, plugging and well interventions, and applies through November 2025.
Drilling may already be under way: the consent applies until November 2025.
The PSA has also authorized Norwegian independent Point Resources consent to use the facilities at Balder, Ringhorne, Ringhorne Øst, and Jotun in the North Sea, following the company’s assumption of operatorship from ExxonMobil.
Balder is an oil field that has been developed using subsea wells tied to an FPSO. Production started in 1999.
Ringhorne, also part of theBalder field, produces through a combined accommodation, drilling and wellhead facility connected to the FPSO 9 km (5.6 mi) to the south and the Jotun A production/storage vessel for processing, crude oil storage and gas export. Production began in 2003.
Ringhorne Øst is an oilfield northeast of Balder which came onstream in 2006. The field has been developed using four production wells drilled from the Ringhorne facility at Balder.
Jotun is an oil field 25 km (15.5 mi) north of Balder, which was developed via the Jotun A and the Jotun B wellhead installation.
Production ceased late last year: under the disposal decision, Jotun B must be removed by 2019, but Jotun A will continue to serve the other three fields until they too stop producing. It is due to be removed by 2023.
