“…A more tide-dominated deltaic setting is indicated for the upper part of the Cook Formation in the Gullfaks area to the east (Dreyer & Wiig 1995). Some authors do recognize a possible westerly source area for deposits in the area of the Statfjord Field (Parkinson & Hines 1995). The regional regression is possibly coupled to a phase of pre-rift doming/tectonic uplift along the eastern flank of the Viking Graben Rift Basin.…”

“…The stratigraphic column for the Statfjord Field shown in Figure 5 is modified after Deegan & Scull (1977) and Vollset & Dore (1984). The chronostratigraphy of the Dunlin Group is adjusted slightly in light of the evaluation of biostratigraphic data from wells and recently published literature (Parkinson & Hines 1995).…”

“…6). The transition from the Lunde Formation (Hegre Group) to the Raude Member of the Statfjord Formation represents a major regional basinwards facies shift (Parkinson & Hines 1995). The general palaeoenvironmental setting for the Statfjord Formation is that of alluvial plain deposits cut by northwards flowing axial rivers with local lateral fans along the graben margins.…”

“…Continued subsidence combined with a regional rise in sea-level resulted in a marine transgression across the area represented by the sandstones of the Nansen member. The Nansen Member is commonly interpreted as timetransgressive and may be underlain by a transgressive erosion surface (Parkinson & Hines 1995). In the Statfjord Field, the three members are informally referred to as $4 and $3 (Raude Member), $2 (Eiriksson Member) and S1 (Nansen Member) (Fig.…”

“…The Burton Formation is overlain by the sandstones and mudstones of the Cook Formation. Sequence stratigraphic studies (Parkinson & Hines 1995;Dreyer & Wiig 1995) recognize a regional regression, or rapid fall in sea-level during the late Pliensbachian-early Toarcian corresponding to the deposition of the Cook Formation. In general, the formation comprises two large scale coarsening upwards sequences consisting of heterolithic sandstones and mudstones deposited in wave-influenced lower shoreface to offshore environments.…”

The Statfjord Field, the largest oil field in the Northern North Sea, straddles the Norway/UK boundary and is located on the southwestern part of the Tampen Spur within the East Shetland Basin. The accunmlation is trapped in a 6-8 ~ W-NW dipping rotated fault block comprised of Jurassic-Triassic strata sealed by Middle to Upper Jurassic and Cretaceous shales.Reserves are located in three separate reservoirs: Middle Jurassic deltaic sediments of the Brent Group, Lower Jurassic marine-shelf sandstones and siltstones of the Dunlin Group; and Upper Triassic-lowermost Jurassic fluviatile sediments of the Statfjord Formation. The majority of reserves are contained within the Brent Group; and Statfjord Formation sediments which exhibit good to excellent reservoir properties with porosities ranging from 20-30% permeabilities ranging up to several darcies, and an average net-to-gross of 60-75%. The sandstones and siltstones of the Dunlin Group have poorer reservoir properties where the best reservoir unit exhibits an average porosity of 22%, an average permeability 300 mD and net-to-gross of 45%.Structurally, the field is subdivided into a main field area characterized by relatively undeformed W-NW dipping strata, and a heavily deformed east flank area characterized by several phases of 'eastward' gravitational collapse.Production from the field commenced in 1979 and as of January 2000, 176 wells have been drilled. The oil is undersaturated and no natural gas-cap is present. The drainage strategy has been to develop the Brent and Dunlin Group reservoir with pressure maintenance using water injection and the Statfjord Formation reservoir by miscible gas flood. However, a strategy to improve recovery by implemeiating water alternating gas (WAG) methods is gradually being implemented for both the Brent and Statfjord reservoirs. Current estimates indicate that by 2015 a total of 666 x 106Sm 3 (4192
