STAVANGER, NorwayEquinor and its partners have committed to develop the Breidablikk field in the Norwegian North Sea via a subsea tieback to the Grane platform.

They plan to produce around 200 MMbbl from Breidablikk, which was discovered by Norsk Hydro in 1991 and subsequently appraised in 2013-14.

The plan for development and operation, submitted today to Norway’s Minister of Petroleum and Energy, involves drilling 23 oil producing wells from four six-slot subsea templates, controlled from Grane.

Breidablikk’s oil will be exported to the platform for processing and then sent through the Grane oil pipeline to the Sture terminal for storage and shipping.

Equinor’s integrated operations center at Sandsli will monitor operations with digital tools to ensure optimal production from the wells.

Development will also include a control umbilical for electricity and communication, a relatively new technology that can facilitate use of docking stations for subsea drones on the seabed, which Equinor is pioneering on the Norwegian continental shelf.

In addition, the PDO calls for one 8-in. gas-lift line and another umbilical for hydraulics and chemicals.

Breidablikk will be phased in during a period of declining oil production at Grane, and phasing-in should reduce the CO2 emissions intensity on the Grane field, Equinor said.

Aker Solutions has the NOK2.5-billion ($261-million) contract for the subsea production system, comprising the templates, trees and associated components. Deliveries will include the company’s standard, lightweight vertical subsea trees and its Vectus subsea control system, said to offer greater data and power capabilities.

Centers at Forenbu and Tranby will perform project management and engineering, with fabrication conducted in Egersund and Sandnessjøen and the service organization in Ågotnes.

In addition, some deliveries will come from branches in the UK, Malaysia, and Brazil.

Wood, the maintenance and modification supplier for Grane, performed the FEED scope for the Breidablikk project, and will be responsible for topsides modifications at Grane under an $84-million EPCI contract.

The company’s duties will include integration of new pipelines and an umbilical, and increasing the platform’s capacity for produced water. Wood will manage engineering in Sandefjord and fabrication in Stavanger.

Breidablikk is northeast of Grane field in 127 m (416 ft) of water, and 185 km (115 mi) west of Haugesund. First oil should flow during the first half of 2024.

Other partners in the development are Petoro, Vår Energi, and ConocoPhillips Skandinavia.
