  Ty Formation
  
  Name

  Ty was a son of the Norse god Odin and was one of the 12 principal gods in Norse mythology.

  Well type section

  UK well 10/1-1 A from 2767 m to 2421 m, coordinates N 59°50'10.50", E 02°00'33.60" (Fig 5.48) . No cores.

  Well reference section

  Norwegian well 15/3-1 S from 2715 m to 2556 m, coordinates N 58°50'57.00", E 01°43'13.25" (Fig 5.49) . No cores.

  Thickness

  The Ty Formation is 346 m thick in the type well. The formation has its depocenter west of the type well, and thins towards the east. It is 159 m thick in the reference well.

  Lithology

  The Ty Formation consists of clean sandstones, generally massive and clear to light grey in colour. Distally the sandstones are interbedded with dark grey shales, but the sandstone bodies tend to be clean.

  Basal stratotype

  The Ty Formation rests on the Shetland Group . The lower boundary represents a distinct change from calcareous sediments into clean sandstones with regular gamma-ray and velocity patterns. The log response changes from low gamma-ray readings and high velocity in the Shetland Group , to higher gamma-ray readings and lower velocity in the Ty Formation sandstones (Fig 5.48) . The boundary may be confused by interbedded shales in the Ty Formation, but the distinct drop in carbonate content distinguishes the formation from the underlying sediments.

  Characteristics of the upper boundary

  The upper boundary is characterized by the transition into the shales of the Lista Formation with higher gamma-ray readings and lower velocity (Fig 5.48 , 5.49). Where the Heimdal Formation overlies the Ty Formation, the boundary is recognized by the change to slightly more erratic log patterns. This boundary may be difficult to identify, but the two formations are normally separated by the Lista Formation .

  Distribution

  The Ty Formation has been identified in the southern Viking Graben, especially in the north-western part of quadrant 25 and the northernmost part of quadrant 15. Its approximate distribution on the Norwegian continental shelf is outlined in (Fig 5.47) .

  Age

  Early Paleocene.

  Depositional environment

  The Ty Formation was deposited in a deep marine fan system which built out from the west.
