Description

WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE

Name Named by Deegan & Scull (1977) from the Forties Field in UK block 21/10.

Well type section UK well 21/10-1 from 2370 m to 2131 m, coordinates N 57°43'50.37", E 00°58'29.19" (Fig 5.44). Cores.

Well reference section Norwegian well 7/11-1 from 3069 m to 2904 m, coordinates N 57°04'15.60", E 02°26'24.40" (Fig 5.46). No cores.

Thickness The Forties Formation is 239 m thick in the type well and 165 m thick in the reference well. The thickness decreases eastwards and southwards into the Norwegian sector.

Lithology The formation typically consists of interbedded sandstones, siltstones and claystones, becoming predominantly sandy higher in the section. The sand is fine to coarse grained, poorly to moderately sorted and contains minor amounts of lignite, pyrite, glauconite and mica. The sands encountered in the Norwegian sector were deposited distally in a lobe, and consist of very fine to fine, angular to subangular grains often with mica and a calcareous cement.

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.
