    Kupferschiefer Formation

    Name
    An old German mining term meaning “Copper Shale”.
    Well type section
    UK well 49/26-4 (Shell/Esso) (see Rhys, 1974) from 2012 to 2013 m.
    Well reference section
    The formation is illustrated in the following wells which may be considered as reference sections. UK wells 30/16-1 (Shell/Esso) (Fig 1.5-8) . 21/11-1 (Shell/Esso) (Fig 1.5-8) and 15/26-1 (BP) (Fig 1.9-11) . Norwegian wells 7/3-1 (Amoco/Noco) (Fig 1.5-8) . and 17/4-1 (Petronord) (Fig 1.9-11) .
    Thickness
    1 m in the type well. In the reference wells it is 1 to 2 m thick and appears to be of the same order of thickness throughout the North Sea Basin. Although typically about 1 m or less in thickness, it can be overlain by additional shale to reach a combined thickness of 10 m; it then loses its sharp spike.
    Lithology
    Thin, grey-black, radioactive, locally calcareous organic-rich shale. In the type well it is a dark brown to black dolomitic shale. In the reference wells it is dark grey to black, carbonaceous and micaceous shale, usually laminated and fissile.
    Boundaries
    The formation is easily distinguished on wireline logs by a very high gamma ray response and low acoustic velocities. Since it normally occurs between the arenaceous sediments of the Rotliegend Group and the carbonates and evaporites of the Zechstein Group it forms a distinctive marker horizon.
    Distribution
    Despite the fact that the formation is very thin it is widely distributed over the Southern and Central North Sea. The Kupferschiefer Formation can be very thin or even absent over local highs and in marginal areas of local paleorelief. It is present on land in the UK and northern Europe.
    Age
    Late Permian.
    Depositional environment
    Marine, anoxic basinal environment.
