Name Norwegian for “alga”.
Well type section Norwegian well 7119/12-1 coordinates N 71°6'08.00'' E 19°47'40.29''.

Lithology The Alge Member forms the lower high gamma intensity part of the Hekkingen Formation and consists of black paper shales rich in organic material.
Lower boundary definition The base is defined by the transition from carbonate cemented and pyritic mudstones to poorly consolidated shales, producing a sudden increase in interval transit time and an abrupt decrease in bulk density values.
Age Late Oxfordian – Kimmeridgian, based on ammonites and palynology.

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.
