Access to information and samples

As recommended by the Wood Review, the OGA aims to make information and samples publicly available as soon as possible.

Accordingly, the 2018 disclosure regulations shortened (in most cases) the length of time that information and samples can remain confidential. However, these new confidentiality periods will generally only apply from 2018 onwards; for legacy data, the rules for release under the 1998 Petroleum Act licence model clauses will still continue to apply.

Offshore technical information is made available either through the National Data Repository (NDR) or the OGA’s Open Data pages. Samples are made available for inspection by the British Geological Survey (BGS).

Well data release agents will continue to make onshore well data available and value-added products from wells already released.

Full details of confidentiality periods under the licence model clauses and the Energy Act 2016 are available in Petroleum Operations Notice (PON) 9 and the OGA’s Guidance on the Reporting and Disclosure of Information and Samples (available on the OGA guidance pages)

If you have any questions about data access or issues relating to Information and Samples in general please contact OGA technical services on OGA.TechData@ogauthority.co.uk

  • Seismic data

    Offshore proprietary seismic data is now made available through the NDR.  

    The OGA has also published supplemental guidance for the reporting and disclosure of geophysical data acquired under an exploration licence. This guidance covers data acquired both pre-2018 and post-2017. Any requests for pre-2018 geophysical data that is eligible to be reported can be submitted to the OGA using this form - “Pre-2018 Geophysical Data Request Form”

    A selection of pre-1992 2D seismic data and more recent offshore data is available from CGG Data Management Services (contact DMS.DigitalProducts@CGG.COM).

    Lynx Information Systems have released a selection of offshore surveys.

    Onshore seismic data

    The UK Onshore Geophysical Library, managed by Lynx Information Systems, releases onshore seismic data. Contact Neil Anderton on (+44) (0) 20 8780 2634 for further details.
