Description

WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE

Name After a fjord on the west coast of Norway, adjacent to the type area in Quadrant 31.

Well type section Norwegian 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 section None at present.

Lithology The 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.

Boundaries The 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

About this data

Norwegian Offshore Directorate (Sodir) FactPages, mirrored nightly and used under the Norwegian Licence for Open Government Data (NLOD). Tops and cored lengths are the Directorate's, per wellbore and unit; the percentiles are computed from those tops and are depths along the wellbore, not true vertical depth.
