• Beskrivelse

  Alge Member
  
  Name

  Norwegian for “alga”.

  Well type section

  Norwegian well 7119/12-1 coordinates N 71°6'08.00'' E 19°47'40.29''.

  Reference well section

  Norwegian well 7120/12-1 coordinates N 71°6'48.71'' E 20°45'20.13''.

  Thickness

  35 m in the type well and 50 m in the reference well.

  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.

  Depositional environment

  The member was deposited in restricted shelf environments.
