Description
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
Name From the Norwegian name for the Polar Fox (Alopex lagopus).
Definition The type section is defined as the interval from 4282 m to 4046 m in well 7229/11-1 on the northern margin of the Finnmark Platform (Fig 9.39); Table 9.1). Eight cores with a total recovery of approximately 180 m, including the base, exist (Fig 9.40). The base of the formation is defined by an abrupt and sharp decrease in gamma ray log response and an accompanying decrease in interval transit time and neutron porosity log response, giving only a slight separation between the neutron and bulk density logs (Fig 9.39). The cored base in the type well shows a sharp transition from underlying laminated silty to very fine-grained sandy carbonates to the overlying carbonate buildups typical of the Polarrev Formation <font color="#08

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.
