Production & development
  • Repsol produces about 30,000 barrels of oil equivalents per day from fields in the Norwegian shelf. It is operator for the Gyda, Blane, Yme and Rev fields and has ownership interests in several others.

    In Norway, Repsol operates the Blane, Gyda, Rev and Yme fields. We also hold interests in a number of non-operated fields with associated production facilities and intrafield pipelines including Gudrun, Brage, Veslefrikk, Visund, Mikkel, Huldra and Tambar East.



The Gyda field was proven in 1980 and developed by the use of an integrated steel platform at a depth of 66 meters. The oil was transported by pipeline to Teesside via Ekofisk. The gas was piped to the Ekofisk complex and on to Emden. 

In June 2017 the Norwegian authorities approved the decommission plan for the Gyda field. The decommission scope includes permanent plugging of 32 wells on the field, removal of platform and undercarriage, as well as removal of installations on the seabed. All Gyda installations should be removed by 2023.

The Yme field was discovered in 1987 located in Block 9/2 and 9/5 in the Egersund Basin, approximately 100 km from the Norwegian coastline. The field was in production from 1996 to 2001. The main reason for abandonment was the combination of high cost and low oil prices. Current licensees were awarded the rights to block 9/2 and 9/5 (production license 316/316B) 18 June 2004. 

A Plan for Development and Operation (PDO) for Yme re-development was approved by the Norwegian Government 11 May 2007. This re-development was based on a lease of a production unit (MOPU platform) that was installed summer 2011. Due to the discovery of significant structural defects on the MOPU it was removed from the field August 2016 and handed over to the platform-owner. 

On 19 December 2017 Repsol submitted a revised Plan for Development and Operation (PDO) of the Yme field to the Norwegian Ministry of Petroleum and Energy. On 23 March 2018 the revised plan was approved by the Ministry.

The Yme New Development Project consists of the engineering, procurement, construction and installation of a new wellhead module on top of existing facilities at the Yme field, the modifications and upgrading of the Maersk Inspirer Mobile Offshore Drilling and Production Unit prior to installation in the field and subsequent hook-up to existing wells in and installations on the seabed offshore. Mærsk Inspirer has previously been used for drilling and production at the Volve field.

From autumn 2018 until 29th of December 2020 the Mærsk Inspirer was at the Aker Solution’s yard in Egersund for upgrading and modifications work at the yard.

The Mærsk Inspirer left the Aker Solution’s yard in Egersund on the 29th of December 2020 and was successfully installed at the Yme field in the Southern North Sea on the 31st of December 2020.

With the installation of the Mærsk Inspirer in the Yme field, the project will now enter the offshore hook-up and commissioning phase. Planned first oil from the Yme field is 2H 2021.

Brage is developed with a platform resting on the seabed, encompassing drilling, treatment and accommodation facilities on a steel jacket. The area’s ocean depth is 140 meters. Originally, the Brage field was supposed to be shut down in 2005. The fields license periode expires in 2015. A license extension to 2030 is now under consideration by the authorities. 1 October 2013, Wintershall took over Equinorl's share in the field and become the operator.

Gudrun is developed with a traditional steel platform resting on the seabed. The platform have capacity for partial treatment of oil and gas, before the hydrocarbons are sent via pipeline to Sleipner.

Oil and gas is transported from the Gudrun field to the Sleipner A platform. The gas is transported onward to the gas markets from Sleipner A. The oil is routed together with the Sleipner condensate to Kårstø for shipping.

Gudrun was first proven in 1975.

Visund is an oil and gas field in blocks 34/8 and 34/7, 22 kilometres north-east of the Gullfaks field in the Tampen area of the Norwegian North Sea.

It came on stream in the spring of 1999, this development embraces a floating production, drilling and quarters platform.

The subsea-completed wells on the field are tied back to the floater with flexible risers. Oil is piped to Gullfaks for storage and export. The Visund field began producing gas and exporting it to continental Europe on 7 October 2005.

Mikkel lies 35 kilometres south of the Midgard deposit on Equinor’s Åsgard field in the Norwegian Sea. It has been developed with a subsea production facility tied back to the seabed installations on Midgard, which in turn form part of the Åsgard development.

The Mikkel system comprises two subsea templates with a total of three production wells.

The condensate will go in existing flowlines to the Åsgard C storage ship for export, while gas is piped through the Åsgard Transport trunkline to the Kårstø complex north of Stavanger. 

Mikkel has been producing gas and condensate (light oil) since 1 August 2003.
