Seismic data

  • 2015 geophysical surveys

    29th Frontier Round data packages are available for download via the OilandGasData portal.

    Subsurface data has been made freely available to support evaluation of two frontier areas which will be available in the 29th Offshore Licensing Round: the North Rockall Basin and the Mid North Sea High/Forth Approaches Basins.

    Data packages are available as a workstation-ready product (Petrel), as well as in software independent formats (eg, SEG-Y, LAS). Data available includes:

    • Processed long-offset, broadband 2D seismic data – pre-stack time migrated (full offset stack and angle stacks) for newly acquired regional surveys
    • Legacy 2D seismic lines supplied by Western Geco, selected reprocessed lines
    • Raw seismic data (SEG-D Field Data) is also be available on request – a media and handling charge will apply
    • Gravity and magnetic data, plus interpreted maps and gridded surfaces
    • Digital data from released hydrocarbon exploration wells including spliced digital well logs, selected well reports and well header information. Refer to Joined Digital Well Logs listing (MS XLS, 0.16Mb)

    Data packages less than 20 GB in size may be downloaded, and larger data packages are available for order on physical media.

    Rockall Trough

    The Rockall Trough area, in the Outer Hebrides is under-explored, with just 12 exploration wells since 1980. It does have a proven working petroleum system - Benbecula discovery in 2000 - but prior to the government funded seismic survey most of the seismic data was pre-1998.

    Mid-North Sea High

    In the Mid-North Sea High area, new advances in seismic acquisition broadband technology, longer streamer length and advances in processing technology can now improve deeper imaging. We targeted deeper Palaeozoic penetration and also acquired data close to shore to transfer critical onshore knowledge.

    In addition to the data obtained and released by the OGA, there are a number of commercial datasets available. Access the map portal for details.

  • 2016 geophysical surveys

    The 2016 seismic data release packages together with well data and other geological information are available for download via the UKOilandGasData portal.

    New, openly-available seismic and well data packages primarily focussed on the East Shetland Platform and South & West of Britain in support of future Offshore Licensing Rounds.

    These Government-Funded data packages are available in industry standard format, as well as workstation ready versions and include: 

    • Processed seismic data, pre-stack time migrated (full offset stack and angle stacks)
    • New 2D broadband acquisition (approx. 19,000 km) from South West Britain (WesternGeco) and the East Shetland Platform (PGS)
    • Reprocessed legacy 2D seismic data (approx. 23,000 km) from North West UK, South West Approaches, East Irish Sea, Celtic Sea, Cardigan Bay, Morecambe Bay, Bristol Channel and English Channel
    • Seismic acquisition and processing reports
    • Database of released well data including joined wireline logs, checkshot and deviation data
    • Synthetic well ties
    • Gravity and magnetic data
    • Field tapes are available to order on NAS drives – a media and handling charge will apply

    Data summary and data package details.

    Digital data from released hydrocarbon exploration wells including joined digital well logs, well reports and well header information is also available as part of the digital data package from CDA .

    Data packages less than 20 GB in size may be downloaded, and larger data packages are available for order on physical media.

    East Shetland Platform

    The East Shetland Platform is an underexplored area adjacent to the prolific East Shetland Basin, with a small number of exploration wells drilled. The new broadband seismic acquisition, amounting to 10,600 line-km, casts new light on this frontier province, together with some 3,600 line-km of legacy 2D seismic that has been re-processed to modern standard.

    SW Britain

    In the SW of Britain, a total of some 8,000 line-km of new broadband seismic data has been acquired, complemented by approximately 16,400 line-km of reprocessed legacy 2D data.
