Description
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
Name Named by Deegan & Scull (1977) after the Andrew Field in UK blocks 18/27 and 16/28.
Well type section UK well 14/25-1 from 2199 m to 1897 m, coordinates N58°01'11.40", E 00°00'56.40". No cores.
Well reference section UK well 21/10-1 from 2464 to 2370 m, coordinates N 57°43'50.37", E 00°58'29.19" (Fig 5.44). No cores.
Thickness The Andrew Formation is 302 m thick in the type well and 94 m in the reference well, which represents the general thinning southwards from the East Shetland Platform. Close to the Fladen Ground Spur, the formation reaches thicknesses of approximately 1200 m.
Lithology The Andrew Formation consists of sandstones with claystone interbeds. The sandstones are generally very fine to medium grained and are composed of subangular to subrounded, clear to orange-stained quartz and feldspar grains. The sandstones are poorly sorted and often have a calcareous cement. Thin stringers of limestone occur.
Basal stratotype The Andrew Formation overlies the shales, marls and limestone interbeds of the Våle Formation, reflected by a higher gamma-ray level in the Andrew Formation. It may also rest on the

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.
