  Reke Member
  
  Name

  Norwegian for “prawn” or “shrimp”.

  Norwegian well 7121/5-1 coordinates 71° 35'54.88''N, 21° 24'21.78''E (Fig 4.46) .

  Well reference section

  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 77 m in the type well, and 84 m in the reference well.

  Lithology

  Sandstone.

  Lower boundary definition

  The lower boundary is defined by the base of a carbonate horizon, where the separation between density and porosity logs decreases markedly. The Reke Member is characterised by a lower, more funnel-shaped gamma ray response than the underlying Akkar Member .

  Age

  Norian - ?Rhaetian (based on palynology).

  Depositional environment

  Coastal and fluvial.
