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.

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.

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.

The Geoscience Australia Boreholes database (BOREHOLE) includes borehole header and directional survey data from: 1. boreholes drilled by Geoscience Australia and its predecessor organisations (BMR, AGSO), 2. all resource exploration boreholes drilled in Australian Commonwealth offshore marine jurisdictions, 3. a selection of Australian onshore mineral exploration, groundwater, geothermal and seismic boreholes, and 4. a small number of research-related boreholes outside of the Australian jurisdiction.

Geoscience Australia is not a reporting or regulatory authority for borehole drilling. Borehole information in the Geoscience Australia Boreholes database is sourced from various regulatory authorities in the States, Northern Territory and Commonwealth governments for Geoscience Australia research purposes. Where Geoscience Australia is not the custodian of borehole data provided in this database, the custodian agency provided with the data should be consulted as the authoritative source.

These data show the location of onshore boreholes registered by the Geological Survey of Northern Ireland that have digital or paper borehole logs. The details given for each borehole includes: the name of the borehole, its unique identifier, the grid reference and depth. Where scans of the boreholes are available to view online a URL is provided in the attribute table. This layer is updated at irregular intervals and the latest data is from June 2023.

The Urban Borehole Database (UBHDB) is a digital compilation of borehole records utilised in urban mapping, 3D geological modelling, and ground shaking studies by GNS Science. This database primarily utilises borehole records from the New Zealand Geotechnical Database (NZGD, www.nzgd.org.nz) and other records provided to GNS Science from engineering consulting companies as well as local government records. The UBHDB is a relational database and contains nine tables; eight down-hole data tables linked to a borehole location / collar table. Down-hole data includes: lithology (descriptions from borehole logs and interpretations of local formation for each down-hole interval), geochronology, shear vein tests, SPT (standard penetration test), structure (structural measurements), survey (borehole orientation), velocity (shear wave velocity), water (static water level measurements). Addition of new data is ongoing and the database is regularly maintained and used for hazard and mapping projects at GNS Science. Data from the NZGD are added to the database in areas of mapping and modelling projects; PDF records from the NZGD are digitised and appended to the database for use in GNS Science research projects.

BGS has drilled almost 600 boreholes to prove seismic interpretations of the marine Quaternary geology and bedrock from the UK Continental Shelf (UKCS). The collection also includes additional third party data and has assisted in the creation of BGS marine geology maps. The boreholes penetrate beneath the sea bed to depths ranging from about 10 m to over 300 m, depending on the target depth or technical problems associated with drilling the borehole. The data include descriptive geological core logs and data which have been captured from these, and in some cases, natural gamma logs. A variety of analyses have been conducted on the core material, such as particle size analysis (PSA), micropalaeontological analysis, geotechnical investigations, palaeomagnetic analysis and age dating. Core material is managed as part of the BGS materials collection and is available for examination and subsampling. The data are stored as part of the National Geoscience Data Centre (NGDC) and the Marine Environmental Data and Information Network (MEDIN) Data Archive Centre (DAC) for geology and geophysics. Data are delivered via the BGS GeoIndex. This dataset is covered by multiple layers, split by the type of material or sampling technique, and the type of data. Borehole-type samples (including boreholes, cores and drills), grab-type samples and other sample types are separated, and there is a metadata layer (containing metadata and links to scanned borehole logs) and a geological data layer (containing depth-bounded geological observations and/or measurements) for boreholes, grabs and other sample types. For borehole-type data, a geotechnical layer containing numerical results of geotechnical tests is also provided. Where available, particle size analysis (PSA) and geochemical data are also provided as separate layers. The data are applicable to a wide range of uses including environmental, geotechnical and geological studies. Reference: Fannin, NGT.

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 Geological Survey of Canada owns and operates slim hole geophysical sondes and recording equipment for use in PVC cased boreholes in unconsolidated overburden. Such holes are commonly drilled and cased for overburden stratigraphic or geotechnical studies related to on-going GSC projects. These boreholes have been located in various parts of Canada and in a variety of differing material types, including glacial, fluvial and lacustrine deposits. Most (but not all) sediments are of Quaternary age. The compilation is offered as a guide to the geophysical response of overburden materials for users planning geophysical surveys in a particular area, and also as a teaching resource for near-surface applied geophysical education programs.

Database of Bore hole metadata and log data with links to other GNS systems that use boreholes. This database aims to be able to record all known information about a bore including logs, publications, post-mortems, and associated data files.

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.

During 2017 and 2018, the U.S. Geological Survey (USGS) Idaho National Laboratory Project Office, in cooperation with the U.S. Department of Energy (DOE), drilled and constructed borehole USGS 145 (USGS site 433358113042701) for hydrogeologic data collection and stratigraphic framework analyses. The well is located along the western boundary of the Idaho National Laboratory (INL) just south of highway 20. USGS 145 was continuously cored from approximately 3 to 1,368 feet below land surface (BLS), and had water level of 704.73 ft BLS directly after drilling. Core was recovered over a two-year period, this includes cored depths from 3 to 678 ft between May 30, 2017,and November 13, 2017, and from 678 to 1,368 ft between May 17, 2018 and July 12, 2018. After coring was completed, the USGS collected geophysical data and finished construction as a dual piezometer well. The general purpose for the drilling and construction of USGS 145 was to improve the understanding of hydrogeology in the west-central part of the INL and to collect geologic data from recovered core. The well is equipped with a 1-in. stainless steel piezometer line and a 0.75-in. stainless steel piezometer line set down to 1,304 and 1,037 ft BLS, respectively. The well was filled with silica sand and cement grout from 740 to 1,368 ft BLS, encasing the piezometer screened intervals of 1,017 to 1,037 ft BLS and 1,277 to 1,297 ft BLS. The USGS collected select geophysical data, daily drilling notes, and detailed core descriptions to 1,368 ft BLS, which are included as part of this data release. The USGS collected geophysical source and deviation logs through drill casing on July 16, 2018 and additional open borehole logs on July 24, 2018. Geophysical data were collected using Century™ multi-parameter logging probes. Geophysical data include natural gamma (tool 9057A), neutron, gamma-gamma density (tool 0024C), and acoustic televiewer (ATV) logs (tool 9804A) which were examined synergistically with available core material to identify contacts between basalt flows and location and thickness of sediment layers. These logs are displayed in the file USGS145_Geophysical_Logs.pdf. Additionally, a gyroscopic deviation survey (tool 9095C) was set to collect data at 0.2-ft increments and used to display the projected well bore path and as displayed in plan view in file USGS145_PlanView_Gyro.pdf and associated well path file USGS145_9095Gyro.asc. Geophysical log data can be obtained by downloading attached LAS files or by visiting USGS - GeoLog Locator. Borehole core from USGS 145 is archived at the USGS Lithologic Core Storage Library located at Central Facilities Area, INL. Drill core was photographed and described using the standardized methods of Johnson and others, 2005. These standardized methods make use of commercially available software that include using a procedure developed by the USGS INL Project Office. The standardized method maximizes description and minimizes interpretation of the borehole core.

The dataset is a subset of Minerals and Petroleum's BORES dataset and contains geological data from Minerals and Petroleum's boreholes RDBMS. The dataset contains any borehole records which have lithological, stratigraphic or assay data as well as any borehole records where the purpose was recorded as being minerals-related.

A borehole is any hole drilled or dug into the ground. The material (soil and or rock) from the hole is collected and tested in a laboratory to find out the structure and type of the soil and or rock beneath the ground. A borehole record or log is a written description of the material that comes out of the ground as a result of drilling a borehole. Geotechnical boreholes are usually shallow (0-30m). They are drilled by engineering companies before building new structures. Before building starts site investigations are carried out to find out the quality of the ground (strength and depth of soil and to see if rock and or groundwater is present). This map shows the location of the Geotechnical boreholes drilled in Ireland that have been submitted to the GSI from engineering companies. It is a vector dataset. Vector data portray the world using points, lines, and polygons (areas).The borehole data is shown as points. Each point holds information on: the location of the borehole (X and Y coordinates), the depth of the borehole (metres) and whether or not bedrock was found at the bottom of the hole.

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

This database of selected borehole records from the Yamal Peninsula, Russia, contains environmental descriptions (textual and numerical) of the units on the index map, and relevant borehole data. The Index Map of Yamal Peninsula (VSEGINGEO-Earth Cryosphere Institute SB RAS; PI - Prof.E.S.Melnikov) was originally compiled at a scale of 1 to 1,000,000, as 'The Map of Natural Complexes of West Siberia for the Purpose of Geocryological Prediction and Planning of Nature-Protection Measures for the Mass Construction, 1 to 1 mln' (1991) by E.S.Melnikov and N.G.Moskalenko (eds.). It was taken as a base map for nature-protection regionalization. Environmental 'regions', 'sub-regions', 'landscapes' and localities' shown on a landscape map are merged into the nature-protection regions. The map was compiled by interpreting more than 1000 satellite images and aerial photos as well as from analysis of field data from several institutions. Dominating components of the landscape, composition of the surface deposits, geocryological conditions and natural protection of ground water were considered while distinguishing the Nature-Protection Regions within the limits of Environmental Regions (Melnikov, 1988). The map is supplied with relevant databases, containing the following information - number of regions and landscape type; category of resiliency; category of the ground water protection; vegetation type; geological and geocryological structure to the depth of 10-15 m; ice content (of lenses and of macro-inclusions separately); thickness of seasonally frozen and seasonally thawed layers; ground temperature; contemporary exogenic geological (periglacial) processes; and the area affected by these processes.The 55 nature-protection regions of Yamal Peninsula generalize information. To approve the ranges of geocryological and cryolithological characteristics, 160 boreholes were retrieved out of the database containing more than 4000 boreholes data obtained in 1977-1990 by Fundamentproekt Design Institute (Moscow, Russia; PI - Dr.sci.M.A.Minkin) at Kharasavey and Bovanenkovo gas fields and along the pipelines Yamal-Ukhta and Yamal-Uzhgorod. The boreholes have reference to geographical coordinates (latitude and longitude), as well as to the nature-protection region numbers shown on the Index Map. A total of 21 units are covered by borehole data, 5-8 boreholes in each unit, covering most typical conditionsThe original database consisted of 3 relational tables. The first table includes category of resiliency; locality type description; landscape type description; ground-ice content, water saturation, cryogenic structure, macro-ground-ice content; vegetation types; seasonally frozen and seasonally thawed layer depths; ground temperature at 10 m; exogenic geological processes an their paragenesis and combinations; and degree of the surface disturbance. The second relational table contains layer-by-layer description of the lithological section types. The third table for the boreholes includes the description of topography around the borehole; types of geological profiles through the active layer and depths down to the permafrost table; ground temperature at 10-m depth (close to the depth of zero annual amplitude in the area); macro-ice content; and salinity of permafrost. These data are presented on the CAPS Version 1.0 CD-ROM, June 1998.
