  Akkar Member
  
  Origin of name

  Norwegian for “squid”.

  Norwegian well 7120/12-1 coordinates 71°6'48.71"N, 20° 45'20.13"E (Fig 4.47) .

  Thickness

  The gross thickness of the member is 55 m in the type well, and 38 m in the reference well.

  Lithology

  Grey to dark grey shales, interbedded sandstones, coal.

  Lower boundary definition

  The base of the Akkar Member (and the Fruholmen Formation ) is defined by a marked increase in gamma ray and neutron porosity logs, but often more moderate increases in interval transit time and bulk density readings.

  Age

  Norian (based on palynology).

  Depositional environment

  Open marine.
