Beskrivelse
Sleipner Formation
NameFrom the Sleipner Field . Sleipner was Odin's eight-legged horse in Norse mythology (Larsen and Jaarvik, 1981).Well type sectionNorwegian well 15/9-2 (Statoil) from 3657 m to 3699 m, coord N 58°25 '34.06'', E 01°42'28.2'' (Fig 3.26) .Well reference sectionNorwegian well 15/12-1 (Statoil) from 3152 m to 3204 m, coord N 58° 10'32.6'', E 01°44'23.6" (Fig 3.27) .Thickness42 m in the type well and 52 m in the reference well.LithologyThe formation consists of a mixed sandstone and silty claystone lithology with coal measures. The sandstones are non-calcareous, light to medium brown, fine to medium grained, with occasional coarse and pebbly layers. The sandstones show a moderate to poor sorting with sub-angular to sub-rounded grains. The silty claystones are medium to dark grey or greyish brown, micromicaceous, hard and slightly fissile. Coal fragments, fossil leaves and root hairs are commonly found. The coals are mature, black and massive, often with thin laminations of silty claystone.BoundariesThe formation lies unconformably on erosional relics of lower Jurassic or older rocks, and a break on dipmeter logs can frequently be observed. Sandstones within the formation in general show lower interval velocites than sandstones in the underlying formations. The upper boundary marks the transition into the shales of the Viking Group or the sandstones of the Hugin Formation . Where the formation is overlain by the shales, clear breaks can be observed both on sonic and gamma ray logs. Where the formation is overlain by the Hugin Formation , the erratic sonic log pattern of the Sleipner Formation becomes smoother when entering the overlying sandstones. On gamma ray logs the sandstones of the Hugin Formation in general appear cleaner, more massive and often thicker than in the Sleipner Formation.DistributionThe formation is found in the southern Viking Graben between approximately 58° and 60°N. The Ness Formation in the East Shetland Basin is broadly equivalent to the Sleipner Formation. The name Sleipner Formation should be applied when the marine sandstones underlying the coaly sequence are absent. Non-marine sands, and associated strata, in the Central Graben and Norwegian-Danish Basin are referred to the Bryne Formation .AgeDepositional environmentThe Sleipner Formation represents a continental fluviodeltaic coaly sequence.Source-
