Description
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
Name The group is named after a fishing bank to the NW of Sørøya, around 71°N and 21°E. The unit corresponds to T5 or the Kvaløy Group of earlier usage.
Type area The most complete sequence seen in the Hammerfest Basin is in Block 7119/12. Blocks 7121/5 and 7120/12 show a thinner development more typical of central and southeastern basin areas.
Thickness The group thins eastwards in the Hammerfest Basin from approximately 250 m in the type area to less than 50 m in easternmost wells and in locations near the southern margins of the basin. The only well drilled to date in the Tromsø Basin penetrated a 1200 m thick development assigned to the group, while wells on the Senja Ridge show a thin sequence, reflecting late Cretaceous structuring of the area.
Lithology Greenish grey to grey claystones with thin limestone intervals in the Tromsø Basin and western parts of the Hammerfest Basin pass eastwards and southeastwards into more calcareous ( 7121/5-1) or sandy ( 7120/12-1) condensed sequences. The claystones are here assigned to the <a href="javascript:void(window.open('https://factpages.sodir.no/factpages/Default.aspx?nav1=strat&nav2=PageView|Lit

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.
