WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
Name The Norwegian word for spawn or hard roe. The formation corresponds to the informally used Frøya Formation.
Well type section 6407/9-1 (Shell), coordinates 64°21'55.39"N, 07°47'21.76"E, from 1670 m to 1621 m (Fig 4.22). Three cores, recovery 35.5 m, including the base.
Thickness 49 m in the type well.
Lithology The formation shows a coarsening upward sequence from siltstones and shales to sandstones which constitute the bulk of the unit.
Basal Stratotype The Rogn Formation is developed within the Spekk Formation in the type well. The lower boundary is defined at the base of a gradual decrease in the gamma ray log and at a sharp decrease in interval transit time shown by the sonic log (Fig 4.21).

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.
