Beskrivelse
Frigg Formation
NameNamed by Deegan & Scull (1977) after a Norse goddess, the wife of Odin.Well type sectionNorwegian well 25/1-1 from 2115 m to 1836 m, coordinates N 59°53'17.40", E 02°04'42.70" (Fig 5.62) . 42 m of cores (1868-1910 m).Well reference sectionNorwegian well 30/7-6 from 1923 m to 1783 m, coordinates N 60°29'29.82", E 02°03'26.14" (Fig 5.63) . No cores.ThicknessThe formation has a thickness of 279 m in the type well and 140 m in the reference well. A depocentre with a maximum thickness of approximately 300 m lies in Norwegian block 25/1.LithologyThe formation consists of sandstones with some lenses and streaks of silty claystone. The sandstones are poorly consolidated, light brown to buff, micaceous and carbonaceous, and very fine to medium, occasionally coarse grained. Some layers have a calcareous cement. Traces of glauconite are present. The silty claystones are green to grey and carbonaceous.Basal stratotypeThe lower boundary normally shows a decrease in gamma-ray intensity and an increase in velocity from the Balder Formation into the Frigg Formation (Fig 5.62) .Characteristics of the upper boundaryThe top of the formation is placed where the sandstones give way to light grey to brown, occasionally green claystone of the Hordaland Group . The boundary is seen on logs as an increase in gamma-ray response and a decrease in velocity (Fig 5.62) .DistributionThe Frigg Formation is found in the southwestern part of quadrant 30, the northwestern part of quadrant 25, and in adjacent areas in the UK sector. The Frigg sands of the Beryl and Brace Fields just extend into the Norwegian sector at about 59°30'N.AgeEarly Eocene.Depositional environmentThe Frigg Formation was deposited as submarine fans, by gravity flows. The mode of deposition led to the formation varying in thickness over short distances. The source was the East Shetland Platform to the west.Source-
