Beskrivelse
Fensfjord Formation
NameAfter a fjord on the west coast of Norway, adjacent to the type area in Quadrant 31.Well type sectionNorwegian well 31/2-1 (Shell) from 1594.5 m to 1741.5 m, coord N 60°46 '19.16", E 03°33' 15.87", (Fig 3.21) .Well reference sectionNone at present.LithologyThe formation consists of sandstones, grey-brown in colour, fine to medium grained, well sorted and moderately friable to consolidated. Calcite cemented sandstones occur in bands containing common bioclastic material. In the type well it is often carbonaceous and occasionally micaceous. Minor shale intercalations occur throughout. The formation has a "serrate" log character, composed of 3-5 m thick units arranged in several cycles.BoundariesThe formation has an overall higher gamma ray intensity and larger FDC-CNL separation than the underlying Krossfjord Formation . The top of the Fensfjord Formation is characterized by a transition in the gamma ray log from a high intensity, serrate log shape to a high intensity but smooth outline in the overlying Heather Formation .DistributionAgeCallovian.Depositional environmentThe formation was deposited in a coastal shallow marine environment.Source-
