  • Description

    Lomvi Formation

    Name
    From the bird (English: guillemot) of the same name.
    Well type section
    Norwegian well 33/12-5 (Mobil) from 3747m to 3867m, coord N 61°11'05.53", E 01°51'53.34" (Fig 3.2) .
    Well reference section
    Norwegian well 33/5-1 (Norsk Hydro) from 3220 m to 3298 m, coord N 61°44'46.10", E 01°34'47.40" (Fig 3.3) .
    Thickness
    120 m in the type well, 78 m in the reference well.
    Lithology
    The Lomvi Formation consists of fine to coarse-grained kaolinitic sandstone with subordinate and thin red marls and claystones. The sandstones, which are light brown, grey or white, are generally more coarse-grained in the reference well than in the type well.
    Boundaries
    The lower boundary represents the transition from interbedded sandstones and marls to the coarse-grained sandstones of the Lomvi Formation. The upper boundary, in the Statfjord Field area, is chosen at the base of the first thick argillaceous unit belonging to the Lunde Formation . Gamma ray log patterns are more regular in the Lomvi Formation than in the overlying and underlying formations.
    Distribution
    The Lomvi Formation is present in all deep wells between the Brent Field and the southern edge of the Møre Basin.
    Age
    Triassic; no more precise dating available.
    Depositional environment
    The Lomvi Formation most probably consists of fluvial deposits.
