Beskrivelse
Eldfisk Formation
NameWell type sectionNorwegian well 2/7-3 (Phillips) from 3626 m to 3695m, coord N 56°23'02.9", E 03°14'45.9" (Fig 3.40) .Well reference sectionNorwegian well 1/9-3 R (Statoil) from 4359.5 m to 4386.5 m, coord N 56°24'56.2", E 02°54'15.15" (Fig 3.43) .ThicknessLithologyThe Eldfisk Formation consists predominantly of sandstone but contains substantial interbeds of shale. In the type well the sandstone is dark yellowish brown, fine to coarse grained, poorly sorted and generally angular, while the shale is medium light grey to dark grey. Both the sandstone and the shale contain calcareous streaks which produce high amplitude peaks on the sonic log.BoundariesThe sands of the Eldfisk Formation are entirely enclosed within the thick upper Jurassic shale sequence of the Central Graben. The Eldfisk Formation is therefore easily distinguished from the underlying Haugesund Formation and the overlying Farsund Formation by its lower gamma ray readings.DistributionAs defined at present, the main development of the Eldfisk Formation is confined to the region of the Eldfisk Field , although thin time equivalent sands are present in other parts of the Central Graben.AgeKimmeridgian.Depositional environmentThe Eldfisk Formation represents an influx of sand into the axial portions of the Central Graben at a time of regression, and for this reason it is postulated that the formation is turbiditic in origin. However, no conventional cores have been taken in the sands and there is no definitive sedimentological evidence.Source-
