Description
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
Name From the Norwegian word for a boathouse. The formation corresponds to the informal Sula Group (H7).
Well type section Well 6507/12-1 (Saga Petroleum) coordinates 65°07'01.62"N, 07°42'42.61"E, formational base at 1342 m (Fig4 .39). No cores.
Thickness The base of the overlying, dominantly glacio-marine deposits is not yet defined. Precise thicknesses are therefore unknown, but generally the Naust Formation is several hundred metres thick in the Haltenbanken-Trænabanken area.
Lithology Interbedded claystone, siltstone and sand, occasionally with very coarse clastics in the upper part.
Basal Stratotype The base is defined by a decrease in interval transit time and gamma ray response and an increase in the resistivity log readings.
Lateral extent and variation The Naust Formation is laterally continuous across the Mid-Norwegian Shelf.
Age Late Pliocene.
Depositional environment The formation was deposited in a marine environment. A transition to glaciomarine environments occurs in the upper part, but this transition is poorly documented

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.
