• Description

  Egga Formation (informal)
  
  The Egga Formation (also referred to as Egga Member or Egga sandstone unit) has been encountered in a number of wells in the Møre Basin and Slørebotn Sub-basin. It comprises sandstones of Danian age and is interpreted as deepmarine massflow deposits. The development of the Egga Formation is illustrated by well 6305/7-1 . Wells on the Ormen Lange Field where it is the main reservoir unit have shown thicknesses of 40 to 80 m, while wells further east and south have encountered thicker sand-rich intervals. The Egga Formation is named informally, no well type nor well reference sections have been established.
