Full Survey Description

The subsurface data is made freely available to support evaluation of the frontier or underexplored UK part of the Greater 'Mid North Sea High' (the UK sector of the North Sea) under the Open Government License v3.0. The dataset was released in 2016 to stimulate the 29th UK Offshore Licensing Round.

    Available Data

    2D Seismic:

    • 2015 OGA survey - full / near / mid / far / ultra-far angle stacks: 56 lines.
    • 2015 Reprocessed Legacy data - final/raw stacks: 26 lines.
    • Legacy data - 14 surveys: total of 178 lines.

    Horizons:

    • 2D horizons interpreted on 2015 OGA survey and gridded by Schlumberger Data Services:
    • Water Bottom
    • Top Chalk
    • Base Chalk
    • Upper Permian (Zechstein)
    • Base Zechstein

    WellsLogs:

    • Well database contains 98 wells:
    • Well tracks from CDA.
    • Checkshots from CDA.
    • Well logs: raw logs from CDA and joined logs from Schlumberger Data Services.
    • Well tops from BGS.
    • Note: In OpendTect time surveys all wells must have Time-Depth models, therefore wells without any such data use an arbitrary model based on constant velocity of 2000 m/s.

    Faults:

    • 18 fault stick sets (Schlumberger Data Services).
