This layer of the Map based index (GeoIndex) shows the location of records of boreholes, shafts and wells from all forms of drilling and site investigation work. Some 850,000 records dating back over 200 years and ranging from one to several thousand metres deep. Currently some 50,000 new records are being added to the collection each year. The dataset available via the GeoIndex is a snapshot, taken at a particular date, of the Single Onshore Borehole Index. Although the GeoIndex is updated at regular intervals more information may be available than is shown.

This layer of the Map based index (GeoIndex) shows the location of registered samples of drillcore and washed cuttings from onshore boreholes drilled in UK by BGS, commercial and public bodies, representing almost 10,000 boreholes. There is also a drillcore collection taken from onshore boreholes drilled in England and Wales by the BGS and commercial and public bodies.

The UK Onshore Geophysical Library was established in 1994 in conjunction with the Department of Trade and Industry (DTI) and the UK Onshore Operators Group (UKOOG). The Library manages the archive and official release of seismic data recorded over landward areas of the UK. By agreement with the DTI and HMSO, the Library operates as a registered charity, funded by revenues raised from data sales and donations, with the long term objective of bringing all available UK onshore digital seismic data into secure archival storage, whilst providing efficient access to all interested parties. BGS has access to the data at cost of copying only for science budget work. Data index on the BGS Geoscience Data Index.

This layer of the map based index (GeoIndex) shows the location of hydrocarbon wells known to BGS. Exploration for hydrocarbons by drilling began in the 19th century and locations were recorded in latitude/longitude until about 1960. These locations have been converted to national grid. The majority of the wells have formed part of basin studies by BGS and are therefore reliably located. There may be some discrepancies in location data between various databases, originating from project modifications and which original source was preferred.

This layer of the map based index (GeoIndex) shows the location of drillcore, bulk specimens, unwashed cuttings and processed material from onshore boreholes drilled in UK by BGS, commercial and public bodies. The majority of borehole cores and samples are available for study and sub-sampling by bona fide academics and commercial companies. Commercial companies are charged for access; academics will need to complete an academic waiver form.

This layer of the map based index (GeoIndex) shows the location of onshore UK boreholes known to BGS that have digital or paper geophysical borehole logs. The details given for each borehole are, the name of the borehole, the grid reference and the format, ie. paper or digital. Scattered distribution of boreholes, locally dense coverage, few logs from Scotland. The GeoIndex is updated at regular intervals but more information may be available than is shown at any one time.

This layer of the map based index (GeoIndex) shows the location and name of active mineral workings in the UK and is derived from the BGS BritPits (British Pits) database. The BritPits database of onshore mineral workings in the UK is based on the records of the BGS, the Coal Authority, industry sources and the Valuation Office Agency (Minerals) and is maintained by the BGS Onshore Minerals and Energy Resources Programme. The database describes individual workings, both currently active and formerly worked, in terms of name, location (including Mineral Planning Authority), ownership, basic geology, commodity produced and end-uses. Contact details including the operator name, address, postcode and telephone and fax numbers are held where known. The location of over 6000 workings are held, with about 2000 currently being worked. The data can be produced digitally, under licence, in formats to meet customer requirements, such as locations of workings or operator addresses, and is suitable for use in GIS applications using the British National Grid. Although the GeoIndex is updated at regular intervals more information may be available than is shown at any one time.

The deliverables from the first year of the UKCS Petroleum Systems Project are being released in support of the 32nd Licensing Round. This initial year was carried out in collaboration with Lloyd’s Register, IGI and the British Geological Survey (BGS) and has focused primarily on the compilation of a UKCS-wide geochemical database. The majority of the entries in the database represent legacy geochemical data collated from CDA (now NDR), the core/cuttings accessions database (held by the BGS on behalf of the OGA) and other geochemical data previously released by the NSTA. The database also includes new fluid analyses that have been carried out to fill data gaps. The database contains over 91,000 samples which have been extracted from more than 2700 wells (onshore and offshore) and a consistent stratigraphic framework has been applied to enable the user to be able to query the database according to stratigraphic intervals of interest. As such, this represents the largest publicly available geochemical database ever compiled for the UKCS. The geochemical database is being made available in p:IGI and Excel format and is provided as a single UKCS database as well as 5 regional reports. Due to the volume of the data provided in the Excel files, the data has been grouped and colour coded for ease of use and the user is encouraged to read the available documentation provided before using the geochemical database. High level interpretation reports are also provided for each region of the UKCS. In addition to the geochemical database, shallow seismic interpretation has been carried out across the UKCS using a coarse, regional 2D seismic grid. The objective was to identify features on the seismic data that may indicate the presence of hydrocarbons or a working petroleum system. These have been mapped and categorised and are represented within the ArcGIS project. Other deliverables of the project include petrophysical TOC evaluations for potential source intervals in the Devonian and Middle Jurassic and a set of integrated regional depth maps. As a result of the NSTA getting geochemical data extracted from core/cutting sample data reported to the BGS, the BGS’s accessions database is now fully available in digital format. Information linked to data reported for both offshore and onshore samples can be queried via layers provided by the BGS as part of their Onshore and Offshore Geoindex pages: For the Onshore Geoindex, the accessioned data layer is under Deposited Data and can be accessed via this link: https://mapapps2.bgs.ac.uk/geoindex/home.html For the Offshore Geoindex, the accessioned data layer is under Oil and Gas (NSTA) and can be accessed via this link: https://mapapps2.bgs.ac.uk/geoindex_offshore/home.html The geochemical database produced as part of the UKCS Petroleum Systems Project is made available under the terms of the OGA’s User Licence Agreement. All other deliverables are released under the OGA Licence (OGAL), the terms of which can be found in the documentation included with this delivery.
