• Description

  Hugin Formation
  
  Name

  One of Odin's two ravens in Norse mythology.

  Well type section

  Norwegian well 15/9-2 (Statoil) from 3483 m to 3657 m, coord N 58°25' 34.06" , E 01 °42'28.2" (Fig 3.26) .

  Well reference section

  Norwegian well 15/6-5 (Esso) from 3627 m to 3679 m, coord N 58°30'29.67", E 01 °45' 50.4" (Fig 3.28) .

  Thickness

  The formation is 174 m thick in the type well and 52 m thick in the reference well.

  Lithogy

  The formation consists of light brown to yellow, very fine to medium grained sandstones. Occasional coarse grained layers are found. The sandstones have fair sorting, and the grains are subangular to subrounded. Shale and siltstone partings are common. Carbonaceous material and coal fragments are abundant. Occasional thin coal beds can be observed. The sandstones are often bioturbated, but cross bedding can sometimes be observed. The sandstones are often calcareous and glauconitic.

  Boundaries

  The lower boundary represents the transition from the coaly Sleipner Formation . The upper boundary represents the transition into the shales of the Viking Group , giving clear breaks both on sonic and gamma ray logs.

  Distribution

  The formation is found in the southern Viking Graben, north of the Jæren High.

  Age

  Early Bathonian to Early Oxfordian.

  Depositional environment

  The formation represents near shore, shallow marine sandstones with the occasional influence of continental fluviodeltaic conditions.
