The National Hydrocarbons Data Archive (NHDA) is the primary, long-term data archive for the geoscientific legacy resulting from UK offshore oil and gas exploration and production activity. The NHDA is operated by the British Geological Survey (BGS) under agreement with the Department of Energy and Climate Change (now BEIS). Examples of potential uses of archived data are: hydrocarbon exploration, field redevelopment and carbon dioxide sequestration projects.

The NHDA offers the only way for Licensees to obtain permanent relief from their otherwise perpetual obligation to retain Licence Data. The preferred archiving route for CDA members archiving well data and processed seismic data is via the CDA Well DataStore and CDA Seismic DataStore. Details of the archive process, including data types and standards, are described in the NHDA Archive Handbook.

Information on well and seismic data archived with the NHDA is available on UKOilandGasData (formerly DEAL). See also NHDA Data Holdings(below) for a general list of wells, seismic surveys, licences and field archived with the NHDA.

Records storage NHDA holdings

The bulk of the data archived are for wells and seismic surveys, and associated exploration licence information. Hutton is the only field that has been archived so far. In addition to the wells and a 3D seismic survey, the field data includes geological models and production data.

The NHDA holds a wide range of geoscientific data, either as digital data or as scanned images.

Abstract machinery Using the NHDA

NHDA data are available to the public at low cost, and can be used for both commercial projects and academic research.

Report More information about the NHDA

The NHDA is one of several measures adopted by PILOT (formerly the DECC's Oil and Gas Taskforce) to stimulate exploration and development in the UK. More about the NHDA's regulatory context, who should archive and the benefits of archiving.
