State-owned Norwegian energy giant Equinor has unveiled a development concept that aims to combine several discoveries in the North Sea into a single project, with total resources estimated at approximately 240 million barrels of oil equivalent, making it one of the largest early-stage development projects on the Norwegian Continental Shelf (NCS).
Equinor and its partners have agreed on a concept Western Ring Roada major subsea development project associated with TrollB platform In the Norwegian sector of the North Sea. This project includes: Grospex, Swisher, Mulder, employment, Duck top, Southern thiefand North thief Discoveries, along with probability Green doctrinewith resources distributed across eight licenses, which have a total of seven owners.
In the wake of the company recently Declared transactions With Aker BP, pending government approval, Grosbeak’s ownership structure within PL 090JS includes Equinor (operator, 21%), Inpex Idemitsu Norge (40%), Wellesley Petroleum (5%), Vår Energi (15%), and Aker BP (19%). While Grosbeak’s partners in PL 925 are Equinor (operator, 66%), Wellesley Petroleum (5%), Vår Energi (10%), and Aker BP (19%), Grosbeak in PL248I includes Equinor (operator, 36%), Petoro (40%), Wellesley Petroleum (5%), and Aker BP (19%).
Kveikje’s owners in PL 293B/CS are Equinor (operator, 51%), DNO Norge (20%), Inpex Idemitsu Norge (10%), and Aker BP (19%). Swisher’s portfolio in PL 24BC includes Equinor (operator, 26%), Petoro (40%), Wellesley Petroleum (15%), and Aker BP (19%). Mulder partners within PL 090 are Equinor (operator, 45%), Inpex Idemitsu Norge (15%), and Vår Energi (40%).
The upper basin of PL 630 includes Equinor (operator, 76%), Wellesley Petroleum (5%), and Aker BP (19%). Røver Nord/Røver Sør in PL 923 includes Equinor (operator, 61%), Petoro (20%) and Aker BP (19%). Grønngylt’s PL090 is owned by Equinor (operator, 45%), Inpex Idemitsu Norge (15%), and Vår Energi (40%).
As operator of all licences, Equinor acted as the area engineer and together with partners evaluated various solutions to determine which discoveries would be included in the development as well as the host platform. This concept agreement is said to represent an important milestone in the maturity of the project, establishing a development solution for seven discoveries and one prospect, while paving the way for the development of a potential joint field.
Ketel HofEquinor’s Executive Vice President, Exploration and Production Norway, commented: “We estimate that Ringvei Vest will contribute 240 million barrels of oil equivalent. A strong effort has been made over a long period, and I am confident that, together with partners and authorities, we have come up with the best development solution, which also ensures optimal use of resources.
“The Norwegian continental shelf is maturing, new discoveries are smaller and costs are increasing. To maintain a high level of activity and reliable energy supply to Europe, it is important to develop marginal discoveries near existing infrastructure and collaborate across licences. Equinor aims to increase our equity production from the Norwegian continental shelf to 1.3 million barrels per day in 2035.”
Ringvei Vest covers a large area, and the plan is to drill a total of 13 wells through six templates. The well stream will be separated on the seabed before being transferred to Troll B, which also supplies power to the subsea facilities. It is planned that the wells will be controlled from the platform, and then the oil will be transported to Mongstad and the gas to Kolsnes.
Plans also include a new compressor on Troll B to increase processing capacity at the platform, which is partly operated from shore, enabling oil and gas production at Ringvei Vest with lower greenhouse gas emissions.
Equinor claims that a continuation decision (DG2) is scheduled to be made at the end of the year, while the timeline for a final investment decision (FID), submission of the development and operation plan, and start of production has not yet been determined.
