Fulla Field Development Profile
Location and Geology
- The Fulla field is located in the Yggdrasil area (previously known as NOAKA - North of Alvheim, Krafla, Askja) in the central North Sea, offshore Norway. It is situated approximately 10-15 kilometers northeast of the Frigg field.
- The water depth in this region is around 110 meters.
- The reservoirs of the Fulla field contain gas and condensate in the Middle Jurassic sandstone of the Brent Group, specifically within the Tarbert Formation, which features delta front and estuarine depositional environments. These reservoirs are at depths of 3,600-4,000 meters and are structurally complex with varying properties.
Discovery and Reservoir Details
- The Fulla field was discovered in February 2009 by the wildcat well 30/11-7, which was drilled to a vertical depth of 4,067 meters below the seabed in the Lower Jurassic sandstone formations of the Brent Group.
- The discovery proved the presence of lean gas condensate in the sandstones of the Ness Formation.
Ownership and Partners
- The Fulla field is owned by Aker BP (operator), Equinor, and LOTOS (or PGNiG Upstream Norway in some sources). The ownership percentages are slightly conflicting between sources, but generally, Aker BP holds around 40-47.7%, Equinor holds around 40-47.7%, and the remaining percentage is held by LOTOS or PGNiG Upstream Norway.
Development Plan
- The Fulla field is being developed as part of the larger Yggdrasil project, which includes the development of several fields in the area, such as Munin, Hugin, and the redevelopment of Lille-Frigg and potentially Øst Frigg.
- The development concept involves a subsea template with six slots tied back to the Hugin A production, drilling, and living quarters platform located in the southern part of the Yggdrasil area.
- The field will be produced using pressure depletion, and the produced output will be transported to the Hugin field for further processing and transport.
Infrastructure and Contractors
- The project involves the installation of a subsea production system, including wellheads, vertical subsea trees, a subsea control system based on Vectus™ 6.0 electronics modules, and other tie-in and connection systems. Aker Solutions, as part of the Subsea Alliance with Aker BP and Subsea 7, is responsible for the subsea production systems.
- Aker Solutions also holds contracts for the front-end engineering and design (FEED) and engineering, procurement, and construction (EPC) for the Hugin A and Hugin B platforms. Other contractors include Siemens Energy for electrical and control systems, Subsea 7 for subsea umbilicals, risers, and flowlines (SURF), and Heerema Vlissingen for the Munin jacket construction.
Power and Environmental Considerations
- The Fulla field will be powered from the shore with a cable from Samnanger through a compensation station on Fitjar, utilizing up to 150MW of electricity from the mainland grid. This setup establishes the world’s longest AC power connection from shore, spanning approximately 250 kilometers.
Investment and Production
- The Yggdrasil project, which includes the Fulla field, is estimated to require an investment of more than NOK115 billion ($11.7 billion) to extract the estimated reserves of 650 million barrels of oil equivalent.
- Production from the Fulla field is expected to commence in 2027, coordinated with the development of the Hugin and Munin fields in the Yggdrasil area.
Digital Transformation
- The development of the Fulla and NOA fields is part of a broader initiative to leverage digital transformation. Aker Solutions, in collaboration with Aker BP, Aize, and Cognite, is developing a digital twin to streamline project development, aiming for significant cost and schedule savings through advanced capabilities such as data exchange, automation of engineering and construction drawings, and construction optimization.
Resource Estimates
- The Fulla field is estimated to contain recoverable reserves of approximately 12.6 million standard cubic meters of oil equivalent, according to the Norwegian Petroleum Directorate (NPD) data.
- The broader Yggdrasil area is estimated to contain total recoverable resources in excess of 700 million barrels of oil equivalent.
