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 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.
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.
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 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.
The borehole information pack from borehole GGB04, 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 4th July and 1st August 2019 (start of drilling to casing installation date) to 16 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/528083 DOI https://dx.doi.org/10.5285/d31f33b8-b34a-4843-b2d2-545722bf94ae
The collection of over 19,000 site investigation reports for Scotland and Northern England consists of records of boreholes, trial pits, geotechnical results and interpretative reports acquired from various sources. The collection started c.1960 to cater for the increasing amount of post-war shallow drilling for building and road construction which was kept separately by the Survey from the Borehole Journal collection reserved for deeper geologist examined mineral bores. The site investigation reports are available for consultation on microfilm. Only the factual parts of reports are available for public inspection. Reports for Northern England are held in the Shallow Borehole File (SB), now no longer added to. All site investigation reports (except SB files) are indexed on the Land Survey Record Index (LSRI) and all boreholes and trial pits contained in the reports (those with adequate site plans) are indexed on the Single Onshore Borehole Index (SOBI).
The Geophysical Borehole Log index provides details of hardcopy geophysical logs known to BGS. The index provides the storage location of the logs and details of the format they are available in, eg. paper, at a scale of 1:200. The data is updated when new data becomes available. Contains most geophysically logged bores known to BGS National Geological Records Centre. Scattered distribution of boreholes, locally dense coverage, few logs from Scotland.
Index to reports of site investigations produced by external organisations carried out for all forms of site investigation. The Oracle index was setup in 1988 and covers the whole of Great Britain, all site investigation reports are indexed but the level of detail in the index for each record may vary. The reports date back to the 1950's and may contain information on boreholes, trial pits, laboratory tests and chemical analyses etc.
