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.

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.

An on-line interactive map showing borehole data for Germany. Coverage is for selected regions only. The data shows locations depths and owners of boreholes but not geological information. The borehole location map contains the topographic backdrop map of different sources (depending on the scale factor) with symbols for borehole locations shown in scales better than 1:100000. The best details are shown on the basis of the 1:50000 scale map series (TK50). All backdrop maps originate from Bundesamt für Kartographie und Geodäsie (BKG). More detailed maps (e.g. TK25 or DGK5) are not available in this application. The connected database does contain master data sets for all boreholes. Further freely available details, e.g. strata or groundwater data, are provided via WFS technology and are displayed in the map client. Non-freely available data can be ordered by contacting the State Geological Surveys.

Contains mineral, petroleum, coal & groundwater boreholes. Minerals boreholes (and, to a lesser extent, petroleum wells) are actively maintained in the dataset. The custodial role for groundwater and coal boreholes is in the private sector, and these parts of the dataset are not actively maintained.

Mineral, petroleum and coal boreholes are updated on an irregular basis: Mineral borehole data are supplied by individual companies usually when their overlaying Exploration Licence expires; Coal borehole data have been updated from GHD Pty Ltd's (formerly GEO-ENG) data. Groundwater boreholes have not been updated since 1990 when the custodial role was given to Sinclair Knight Merz Pty Ltd (SKM) - refer to BORES100.

The origin of data varies considerably. Prior to 1980 borehole data was recorded by the Geological Survey of Victoria (GSV) on 1 inch:1 mile plans and hard-copy borehole records. This included data for water boreholes drilled by public and private sector, all boreholes drilled by GSV, petroleum wells, and some private-sector mineral exploration boreholes. In areas where drilling was of particularly high density, locations were recorded on these plans as a single point or as occurring within an outlined area.

The parish was traditionally used as the primary classifier for numbering boreholes. Some minor anomalies exist where a borehole and parish boundary may be on one side of a road or the other, or where parish boundaries have been moved.

In 1980 the location data was moved to 1:100,000 AMG plans. In the mid-1980s a program of electronic capture commenced. Borehole locations were digitised from the 1:100,000 plans with an accuracy of +/-300m. For the areas of high borehole density where boreholes were plotted on a single point, often only the first ten and last ten were recorded in the database. Boreholes whose parish was known but exact location was unknown were also recorded, but do not have a location.

Groundwater boreholes: Extensive hydrological data was originally held by GSV, but these data are now held by SKM.

Coal boreholes: Location and lithological data for coal boreholes has been provided by Geo-Eng and the old State Electricity Commission of Victoria.

Mineral exploration boreholes: The capture of mineral exploration borehole data from open-file exploration reports commenced in 2001 and will progressively cover the state over a number of years. The data are being captured at an whatever accuracy the source allows, typically between 20 and 250 m. Assay data have been consistently captured. Other downhole data, such as lithology, have not been consistently captured.

Tenement information for the small number of private-sector mineral exploration boreholes captured prior to 2001 was lost in the migration from the original VAX database to the current Ingres corporate database.

Heavy mineral sand exploration: complete coverage up for data up to April 2002; updates planned for late 2003. Other mineral exploration: coverage as follows - St Arnaud, Charlton, Wedderburn 1:100 000 mapsheets - 31 March, 2001; Dunolly, Rupanyup, Donald, Ararat, Grampians, Willaura 1:100 000 mapsheets -\t30 August 2001; Warburton 1:250 000 mapsheet - 30 June 2002 (available mid-2003); Ballarat, Creswick, Skipton, Beaufort 1:100 000 mapsheets - 30 June 2002 (available mid-2003); Bendigo 1:250 000 - 31 October 2002 (available mid-2003)

We are providing: Downloadable CSV files containing borehole data (potentially 9 tables, including the metadata table) An entity relationship diagram available at:http://gmw.consrv.ca.gov/shmp/shmp_web_geodata_erd.doc Note that the borehole dataset contains multiple tables. It is important to understand what is (and is not) included with this data set. Accordingly, please review the descriptive files before beginning to use the data. Also, we address below some of the issues that one should be aware of when using these data. We have compiled existing borehole data from the files of cities, counties and other public agencies. We cannot vouch for the accuracy or precision of any of the data because we did not participate in the initial fieldwork involved in its generation. Nevertheless, we have strived to select for our files only those logs with adequate documentation and of sufficient quality that we judge are appropriate for use in our mapping efforts.

We attempt to capture the data and compile them in our database in a way that represents, as closely as possible, what is shown on the boring logs and presented in the reports that accompany them. However, a range of individuals, from licensed, experienced geologists on our staff to relatively inexperienced student assistants has been involved in entering the data into our database. It is likely that all of these individuals did not follow exactly the same procedures (no matter how well defined) during data entry. Naturally, because not all drilling-rig operators and on-site geologists or engineers use industry standard descriptions or techniques, we have been forced, at times, to try to translate nonstandard data and nomenclature to standard, or consistent, nomenclature and values.

Variations in our methods of locating borings and estimating the elevation of the ground surface where the boring was made depend upon several factors. These include: the type of maps presented in the report; the documentation in the report and on the log; the terrain information available in our GIS system; and the vintage of the map we use to locate the boring. In some cases, the best available topographic maps that we use to locate borings and estimate elevations predate changes due to local development and grading.

Difficulty in discerning from the log and associated report all of the parameters used in making the boring is very common. Occasionally, we have been required to make deductions and assumptions about how the borings were advanced.

A few parameters (for example, dry density) can be recorded exactly as presented on the log or on the associated laboratory data sheets. Alternatively, because not all labs and firms report parameters the same way, we may translate the data to a different form for recording in our database."

Soil descriptions are taken verbatim from the logs/reports. However, in a very few cases we have had to supplement or correct apparent errors in descriptions or classifications that were omitted from the original log or incorrectly reported.

We hope that you are successful in using these data. Feel free to contact us with questions or comments.

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.

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.

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.

A borehole is any hole drilled or dug into the ground. The hole is usually deep, narrow and round. 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. Bedrock boreholes are usually deep (can reach up to 1000m). We drill boreholes to improve and update our bedrock, quaternary sediments and groundwater maps. We store the samples (core) and these are available to view by appointment. We’re in the process of scanning all the core and the images will be available online when completed. This map shows the location of the bedrock boreholes drilled in Ireland by the GSI or submitted to the GSI from mineral exploration companies.This Bedrock boreholes map is to the scale 1:50,000. This means it should be viewed at that scale. When printed at that scale 1cm on the map relates to a distance of 500m.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), Borehole ID (borehole identifier), the length of the hole (metres), the angle the hole was drilled, azimuth (direction the hole was drilled), comments, county, 1:50,000 sheet number, prospecting licence number (PL), data source and contains a url to download a PDF of the borehole log.

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.

This layer of the map based index (GeoIndex) providex an index to 17,500 borehole rock samples (drillcore) from the Mineral Reconnaissance Programme (MRP) and related studies. The UK Government's Department of Trade and Industry (DTI) funded BGS to provide baseline information on areas prospective for the occurrence of metallic minerals in Great Britain. This programme, known as the MRP, ran continuously from 1973 to 1997 and covered particular locations across Great Britain. It was designed to stimulate private sector exploration and to encourage the development of Britain's indigenous mineral resources. Under the programme a number of boreholes were drilled to gather information. This layer is only available at specific zoom levels. Please zoom to a larger scale to interrogate the map.

Abstract

This dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied

The NSW Coal Boreholes Database has been developed to record data on coal exploration and development-drilling data for boreholes drilled in New South Wales. The database contains summary information about each borehole such as location, total depth, completion date, etc and references. Only Open File borehole records are available to the public. Borehole coordinates have been obtained from a number of sources including exploration companies and consultants. The accuracy of the locations varies and is often unknown. In many instances the borehole coordinates have been measured off company exploration maps or parish/county maps and these holes have an accuracy of between 25m and 500m depending on the quality of the map displaying the holes. Where a number of boreholes have been drilled on one prospect they will be located accurately relative to each other. This dataset was downloaded from the NSW Geoscientific Data Warehouse.

The COAL.html file provides the complete metadata for this dataset.

This dataset has been provided to the BA Programme for use within the programme only. Third parties should contact the NSW Department of Industry. http://www.industry.nsw.gov.au/

Purpose

To provide geoscientific information to the public about NSW coal boreholes.

Dataset History

Data Quality

Lineage:

The primary data source for the coal borehole database was company exploration reports supplied to the Department of Mineral Resources as part of the statutory reporting requirements for exploration licences. Holes drilled by Industry and Investment NSW (Minerals) are also included in the database. Initially data was held in the COGENT Oracle database. The data was exported into spreadsheets and maintained in this environment for some time. The database is now on a SQL Server platform. Data can be entered or edited using the GBIS program

Positional Accuracy:

Drillhole coordinates have been obtained from a number of sources including exploration companies and consultants. The accuracy of the drillholes varies and is often unknown. In most instances the drillhole coordinates have been measured off company exploration maps or parish/county maps and these holes have an accuracy of between 25m and 500m depending on the quality of the map displaying the holes. Where a number of holes have been drilled on one prospect they will be located accurate relative to each other.

Attribute Accuracy:

The dataset contains a number of attributes (see attribute definitions below), these values have been derived from a large number of sources (see data lineage). Overall accuracy of the attributes will vary according to many factors such as the company that reported the drillhole and the type of lease the hole was drilled on. Some companies provide the Department with exploration reports of very high standard while others submit the bare minimum of information. Likewise, exploration licences (EL's) have fairly stringent reporting requirements while older types of licences and mining leases often have reports of poor quality

Logical Consistency:

There should be a high degree of logical consistency in this data set as data from one drillhole does not depend upon other information

Completeness:

As mentioned in the attribute accuracy the completeness of the data is dependent upon the quality of the data supplied to the Department in company reports. It is not always possible to obtain all the information required for each drillhole.

Maps showing the feasibility of borehole heat exchangers, considering chosen environmental conditions. Maps are the result of spatial analyses showing 3 types (classes) of areas with the division whether there are contraindications to the construction of a boreholes for ground source heat exchangers (GHE): - installation without contraindications - no adverse environmental conditions; - conditional installation - construction of the installation is conditionally possible (local environmental conditions should be analyzed in detail in the geological operations project and taken into account in the technical design of the GHE); - obviously contraindicated installation - execution of the installation is possible with evident contraindications (due to extremely unfavorable environmental conditions). In addition, an area class of ‘surface water’ was distinguished. Maps were produced as part of a project funded by the National Fund for Environmental Protection and Water Management entitled: ‘Assessment of the energy potential and environmental conditions of low-temperature geothermal energy’ carried out between 2017 and 2022.
