  • Description
    Vade Formation

     Name
    Vade is a giant from Norse mythology who wades across the fjords.
    Well type section
    Norwegian well 2/2-1 from 2172 m to 2100 m, coordinates N 56°47'15.69", E 03°38'15.62" (Fig 5.60) . No cores.
    Well reference section
    Norwegian well 2/3-2 from 1855 m to 1795 m, coordinates N 56°54'53.70", E 03°49'02.25" (Fig 5.68) . No cores.
    Thickness
    The thickness is 72 m in the type well and 60 m in the reference well. (Fig 5.69) . shows a seismic section through the Vade Formation which illustrates thinning to the southwest.
    Lithology
    The formation consists of thinly interbedded, light green to grey, very fine grained sandstones and silt-stones. These are glauconitic, slightly micaceous and well sorted. Fossils are present. Reference well 2/3-2 shows that the formation interfingers with the claystones of the Hordaland Group (Fig 5.68) .
    Basal stratotype
    The lower boundary shows a decrease in gamma-ray intensity and an increase in velocity from the claystones of the Hordaland Group into the Vade Formation (Fig 5.60) .
    Characteristics of the upper boundary
    The upper boundary is characterised by an increase in gamma-ray response and a decrease in velocity from the Vade Formation into the claystones of the Hordaland Group (Fig 5.60) .
    Distribution
    The formation has only been penetrated in some wells in blocks 2/2 and 2/3. Its distribution is shown in (Fig 5.66) .
    Age
    Late Oligocene.
    Depositional environment
    The sandstones were deposited in a shallow marine environment. Their deposition can be seen as a response to an eustatic fall in sea level or a tectonic uplift of the area. Regional considerations indicate a source area in the east or northeast.
