Description
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
The Delfin Formation has been encountered in several wells in the northern Vøring Basin. It comprises sandstones of Early Campanian and Late Santonian age and is interpreted as a basin floor fan intercalated into shales of the Nise Formation. Wells show thicknesses of up to more than 1000 metres of good sandstone. The development of the Delfin Formation is illustrated by well 6707/10-1. Well 6704/12-1 is situated in a partly different sub-basin. The sandstones encountered in this well are derived from a slightly different source area.
The Delfin Formation is named informally, no well type nor well reference sections have been established.

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.
