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
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 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.
Data from the British Geological Survey's GeoIndex Collections theme are made available for viewing here. GeoIndex is a website that allows users to search for information about BGS data collections covering the UK and other areas world wide. Access is free, the interface is easy to use, and it has been developed to enable users to check coverage of different types of data and find out some background information about the data. More detailed information can be obtained by further enquiry via the web site: www.bgs.ac.uk/geoindex.
This datasets contains 323 observations of borehole breakouts across and drilling induced tensile fractures from borehole imaging used to re-characterise the UK stress field orientation in 2016. This was published in the Journal of Marine and Petroleum Geology and is openly available using doi:10.1016/j.marpetgeo.2016.02.012 The observations relate to 39 wells from Central and Northern England and are provided with links to screen grabs of the images for clarity. The basic well meta data is supplied along with a description of the dataset. The Images were generated in the IMAGE DISPLAY module of the Landmark RECALL software. and are supplied on an “as shown” basis. Descriptions of the tools and the techniques used are listed in the accompanying paper: KINGDON, A., FELLGETT, M. W. & WILLIAMS, J. D. O. 2016. Use of borehole imaging to improve understanding of the in-situ stress orientation of Central and Northern England and its implications for unconventional hydrocarbon resources. Marine and Petroleum Geology, 73, 1-20.
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.
The Borehole Geology database holds downhole lithological / lithostratigraphical data (with unit-bound lithological properties where appropriate) for boreholes identified within the Single Onshore Borehole Index (SOBI), which covers onshore and nearshore Great Britain. The database can store multiple interpretations for each borehole and properties assigned to each coded lithological unit. Available borehole geology properties include porosity, Munsell colour, grainsize, water struck, etc, and other valid property-types can be included when/if required.
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 BGS collection of downhole CCTV (Closed Circuit Television) recordings and backup tapes for worldwide SKYLAB satellite imagery. CCTV recordings carried out down boreholes, mainly drilled for water, were undertaken by BGS for specific commercial contracts in Great Britain, and may also have associated geophysical data. The collection started in 1997, and the present holdings are 138 videos, with infrequent additions. Video recordings on other topics may be added.
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.
