Description
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
Name From the Norwegian name for algae or sea tangle. The formation corresponds to the informal Alstahaug Formation or H5-2.
Well type section Well 6507/12-1 (Saga Petroleum), coordinates 65°07'01.62"N, 07°42'42.61"E, from 1884 m to 1826 m (Fig 4.36). No cores.
Thickness 58 m in the type well.
Lithology Dark grey, green or brown claystones with some thin sandstone stringers show a variable content of tuff.
Basal Stratotype The base is defined by an increase in tuff content. Consequently the sonic log shows a decrease in interval transit time and an increase in density log readings.
Lateral extent and variation The Tare Formation is ubiquitous except near the crest of the Nordland Ridge. The tuff content decreases southwards.
Age Late Paleocene.
Depositional environment These sediments were deposited in a deep marine environment.
Correlation The Tare Formation is similar in both age and lithology to the <a href="javascript:void(window.open('https://factpages.sodir.no/factpages/Defa

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.
