  • The Single Onshore Borehole Index (SOBI) is an index of over 1 million boreholes, shafts and wells and references collections of digital and analogue records from all forms of drilling and site investigation work held by the BGS. The index covers onshore and near shore boreholes from Great Britain dating back to at least 1790 and ranging from one to several thousand metres deep. Some 50,000 new boreholes are added each year. The majority of the records contain written descriptions of the ground encountered. The SOBI index database originated in 1988 from a number of existing tables and from data input from a variety of coding forms. Therefore not all fields in the database are populated and data that should be in some fields may currently form part of the entries in another. The index is available on the BGS website via the Geoindex

  • The Geotechnical Database contains information about site investigation reports, boreholes and samples. It contains geotechnical measurements taken over borehole intervals and on samples. Some of the data is obtained digitally from AGS files (Association of Geotechnical and Geoenvironmental Specialists - File Transfer Format), some is obtained manually from Site Investigation Reports stored in the National Geoscience Data Centre. The database currently contains geotechnical data from over 450 000 laboratory test samples and core descriptions, borehole observations and in situ tests from over 96 000 boreholes extracted from over 4800 site investigation reports. The database underpins BGS Geo-engineering properties and processes research and is an important information resource for answering enquiries and providing for the data needs of external customers.

  • Site investigation and geotechnical data received by BGS from 3rd party organisations in AGS file format. When received by BGS the data is validated against predefined rules, processed and stored in the BGS AGS agnostic store. This data is delivered as received e.g. no interpretative values or observations are added to the data by the BGS. For more details about the Association of Geotechnical & Geoenvironmental Specialists (AGS) see: https://www.ags.org.uk For more details on depositing AGS data with BGS see: http://www.bgs.ac.uk/data/ags To access AGS data held by BGS: http://mapapps2.bgs.ac.uk/geoindex/home.html?layer=AGSBoreholes

  • The data release includes groundwater chemistry data from 15 samples collected during the borehole test pumping phase at the UK Geoenergy Observatories (UKGEOS) Glasgow facility. This release from the British Geological Survey (BGS) covers groundwater samples collected between 14 January 2020 and 21 February 2020 and then analysed for the concentrations of selected parameters at BGS and other laboratories. It contains a report and 2 data sheets. Further details can be found in the accompanying report http://nora.nerc.ac.uk/id/eprint/531098/.

  • Reports of site investigations produced by external organisations carried out for all forms of site investigation The reports date back to the 1950s and may contain information on boreholes, trial pits, laboratory tests and chemical analyses etc. The collection covers the whole of Great Britain with concentrations in urban areas and transportation routes. The interpreative parts of the reports are not available to public.

  • The Land Survey Record Index was set up c.1988 to provide a digital database index to records and archives held by the Land Survey in Scotland and Northern England and contains over 46,600 records. Finding aid to the following record groups/data sets, is provided through a application query interface: Site Investigation Records (SE); Land Survey Archives (LSA); Land Survey Records (LSR); Mineral Resource Records (MR); Additional Information Files (AI); Enquiry Record Files (EE; EN); Opencast Coal Sites (OC).

  • This document data set contains paper copies of selected geophysical borehole logs made from the master data set held by the BGS National Geological Records Centre (NGRC) at Keyworth. These have been made for interpretation. Most data are within the UK onshore area; although there are some UK near-shore and offshore (North Sea, Irish Sea) and foreign data. Most data were acquired for commercial hydrocarbon exploration and subsequently provided to BGS for use on specific projects. Some data were acquired by BGS and other public-sector bodies for research purposes (e.g. geothermal energy). The documents are dyeline prints or plain-paper photocopies. They are stored folded in boxes, approx 20 logs per box, approx 500 boxes. There are some duplicates. Only a sub-set of the available borehole logs have been copied, usually for deep boreholes or boreholes of special significance in the interpretation of seismic data. Mostly concentrated in areas prospective for coal, oil and gas.

  • 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.

  • The borehole information pack from borehole GGB05, site 05 of the UK Geoenergy Observatories (UKGEOS) Glasgow facility. This release from the British Geological Survey (BGS) contains BGS and Drillers’ logs, a listing of archived rock chips and a descriptive report. The environmental baseline characterisation and monitoring borehole was drilled between 5th July and 11th October 2019 (start of drilling to casing installation date) to 46 m drilled depth. The cased borehole was hydrogeologically tested in Febuary 2020. Rock chip samples were taken during the drilling process and have been archived at the National Geological Repository at BGS Keyworth. Further details can be found in the accompanying report http://nora.nerc.ac.uk/id/eprint/528084 DOI: https://dx.doi.org/10.5285/e0ec7462-b731-47c6-93d6-e4613fb44be0

  • Index of onshore boreholes in England, Wales and Scotland for which BGS holds material either as registered specimens or cuttings. Developed to improve access by BGS staff and external enquirers to the major UK borehole collection.
