Name From the Cromer Knoll buoy in the southern North Sea. Named by Rhys (1974) in the southern North Sea and extended in use to the northern North Sea by Deegan and Scull (1977). The group as now used off mid-Norway corresponds to the informal Finnvær Group (H3).
Type area The type area is in the southern North Sea. Rhys (1974) used UK well 48/22-2 to illustrate a typical section of the group, and Deegan & Scull (1977) used UK wells 29/25-1, 22/1-2A and 3/29-1, and Norwegian well 2/11-1. In the North Sea the following Norwegian wells have been used to illustrate local developments of the group: 2/6-2, 2/7-15, 2/11-1, <a href="javascript:void(window.open('https://factpages.sodir.no/factpages/Default.aspx?nav1=wellbore&nav2=PageView|Exploration|All&nav3=164&menu=No'

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.
