DATA REPOSITORIES

The following links are for data repositories, often Geological Surveys and Government Organisations. They include a range of subsurface data including core, well and seismic data. Please note that not all of these repositories are based in the UK and or include North Sea related geology.

British Geological Survey (BGS)

Wide range of datasets available through the OpenGeoscience portal, including Maps and Sections, Thin Sections and Research Reports. Onshore and Offshore data can be searched through the GeoIndex which contains geological maps, geochemical, geophysical and engineering information, subsurface data, GIS layers and more. The Offshore Hydrocarbon Wells Database which contains >300 km of scanned core material and >4.5 million cutting samples from ~8000 wells.

Faroese Geological Survey (Jarðfeingi)

Surface data from petroleum exploration on and around the Faroe Islands, includes a range of core, well and seismic data, in addition to GIS shapefiles. Please be aware not all data is available online or for free.

Geological Survey of Sweden (SGU)

Database of largely onshore boreholes across Sweden, with additional GIS layers of information. The Geological Survey of Sweden has on ongoing project at the national drill core archive in Malå to scan ~200, 000 meters of drill core from Norrbotten and Västerbotten. Details on the

project, the core scans available and how to use the map view are available here.

International Ocean Discovery Program (IODP)

This is an international marine research collaboration which has conducted a vast number of research expeditions throughout the world's oceans. Access to a wide range of databases is available through a number of portals, with data geochemical, petrophysical and core data. Additional legacy DSDP/ODP/IODP core data can be searched via this map.

National Virtual Core Library (NVCL)

An impressive database of over 1,000,000 metres of core from over 3,000 boreholes across the seven Australian Geological Survey jurisdictions. The data is available through the AuScope project, with more information here.

Oil and Gas Authority (OGA)

Access to a wide range of material, including relinquishment reports, information on hydrocarbon fields and discoveries, licence rounds and awards, offshore boundary polygons and subsurface data, such as seismic volumes and wireline logs. Available through the Open Data portal and the National Data Repository (NDR), most data is available from free or to be viewed online. Please note, industry, academia and the wider public may have to register to search, view and download disclosed information.

UK Geoenergy Observatories (UKGEOS) - Glasgow Facility

An intermediate data release pack from BGS of borehole GGC01, site 10 of the UK Geoenergy Observatories Glasgow facility. Contains sedimentology, discontinuity and engineering logs, composite and digital wireline logs, sample recovery information and a range of core logs and images.

U.S. Geological Survey (USGS)

Access to a wide range of products and data, including geological maps, publications, images and GIS data. Well data can be searched via the USGS Well Catalog or by looking through the available Links to State Well Data. Core data can be found through the Links to Core Repositories. The curation and availability of data varies across the individual geological surveys.
