The Single Onshore Borehole Index (SOBI) is an index of over one million records of boreholes, shafts and wells from all forms of drilling and site investigation work held by the BGS. The collection covers onshore and near-shore boreholes from Great Britain dating back to at least 1790 and ranging from one to several thousand metres deep. Each year thousands of new records are added. Includes scans of paper records and digital records (including AGS).

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 is only available at specific zoom levels. Please zoom to a larger scale to interrogate the map.

Records of all onshore (or near shore) boreholes, trial pits, shafts and wells held in the BGS archives in either paper, microfilm or digital format. The records range from simple single page lithological logs through to hydrocarbon completion reports. Spatial coverage will vary considerably depending on drilling activity, collecting activity and donations. The majority of new data is from site investigation reports with concentrations in urban areas and along transport routes. Current collection over 1million records covering the whole of Great Britain with 50,000 new records added per annum. Some records date back to 1600 but the majority date from 1900 onwards. Copies of records are available in hard copy or digital formats subject to confidentiality.

This dataset is a model output created using the BGS AquiMod model. It provides monthly groundwater level relative to the Ordnance Datum (maOD) from 1891 to 2015, reconstructed for 54 observation boreholes across the UK. Based on the Generalised Likelihood Uncertainty Estimation (GLUE) methodology, 90th percentile and 10th percentile confidence bounds have been estimated and are given for each of reconstructed groundwater level time series.

Records for Great Britain of the statutory notifications of the intention to drill any boreholes, shafts or wells under the Mining Industry Act 1926 or the Water Resources Act 1991( plus voluntary notifications) . Information has been collected and maintained centrally from the 1950's, earlier records however are only on index cards. Complete for all boreholes since 1988 but record data will vary depending on the original purpose. Access restrictions apply.

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.

Monthly Standardised Groundwater level Index (SGI) for observation boreholes across the UK from 1891 to 2015, based on reconstructed groundwater level time series (Bloomfield et al., 2018; https://doi.org/10.5285/ccfded8f-c8dc-4a24-8338-5af94dbfcc16). Standardised groundwater levels have been estimated using a non-parametric normal scores transform of groundwater level data for each calendar month. Probability estimates of an SGI being less than 0, -1, -1.5 and -2 are also provided.

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 dataset is an archive of original data for the geophysical logging of boreholes drilled by the National Coal Board (NCB) and its successor, British Coal Corporation (BCC). Data coverage is UK wide and dates from the 1970's to the privatisation of the coal mining industry, in 1994. The dataset includes approximately 2000 field data recording tapes and processed data tapes. The processed data tapes are at various stages of processing and consist of edited data and computed (CSU) data (not available for all boreholes). The data are kept as archive copies. The data are owned by the Coal Authority (CA), as successor to the NCB and BCC, BGS being the custodian under an agreement with the Coal Authority. No full catalogue or index available yet.

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.

BGS has drilled almost 600 boreholes to prove seismic interpretations of the marine Quaternary geology and bedrock from the sea areas around the UK. The boreholes penetrate beneath the sea bed to depths ranging from about 10m to over 300m depending on the target depth or technical problems associated with drilling the borehole. The data set includes the descriptive geological core logs, core material and in some cases natural gamma logs. A variety of analyses has been conducted on the core material depending on the test requirements for each borehole. The main types of analyses are PSA, micropalaeontological, geotechnical, palaeomagnetic and age dating. Core material is available for examination, testing or subsampling.

Revised dataset available here http://data.bgs.ac.uk/id/dataHolding/13607942 .This dataset comprises 655 borehole records and previously unanalysed pumping tests from across Uganda that were compiled from historical borehole records held within 9 district water offices. The dataset is a compilation of historical borehole records held within nine district water offices across Uganda. These data originated from numerous drilling campaigns undertaken by private contractors in each district to site and construct hand-pump borehole community water supplies between 2000 to 2018. In total over 1000 paper borehole records were initially collated and reviewed. This work was carried out over several months visiting the district water offices. Following a quality assurance procedure 655 records were transcribed to create a digital dataset. Each borehole record in the dataset contains a series of metadata alongside the pumping test data (e.g. pump depth, static water level, pumping rate and duration) including locational information (e.g. coordinates, water strike, borehole depth, borehole lithologies). The dataset is delivered as a series georeferenced site information within an MS Excel spreadsheet file.

"The BGS holds over a million borehole records and these can be viewed online in the dedicated borehole viewer (https://www.bgs.ac.uk/data/boreholescans/home.html). Coverage across Great Britain is clustered (generally within urban centres and corridors). This map only shows borehole data that has been captured to date (additional data may exist). Boreholes are drilled for assessing ground conditions for construction, water and mineral resources. They are generally not drilled for the purpose of recording soil information. However, many boreholes note the depth of deposits classed as 'Topsoil' and so BGS has started to compile a dataset of reported 'Topsoil' depths. Most records suggest that the driller has identified a generic 'Topsoil' layer. Some records provide further details that indicate the topsoil layer has differing properties, or is not solely a topsoil layer but a combination of soil and other materials (e.g. parent material, peat and artificial ground). Users should therefore be aware that the term 'topsoil', as used in borehole records, should be regarded as a very simple description of what soil-scientists might regard as a combination of O, A, E and possibly B horizons."
