Description

WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE

Name From the main fjord in Rogaland, Norway.

Type area The Fiskebank and Egersund Sub-Basins comprise the type area. The group is illustrated in the Norwegian well 9/4-3 (Conoco), (Fig 3.36).

Thickness In the type area wells show thicknesses of up to 500 m. In well 9/4-3 the thickness of the group is 290 m. Towards the basin margins the section thins considerably.

Lithology The sediments of the group are dominated by shales. Varying amounts of siltstone, sandstone, limestone stringers and differences in organic content make it possible, however, to subdivide the group into formations (Olsen and Strass, 1982).

Boundaries The lower boundary is characterized by a distinct log break with the underlying sandstones of the <font colo
