Scanned images of the records of all onshore Great Britain (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. Current collection over 1million records with 50,000 new records added per annum. Scanning started in 2002 and is ongoing with new records being scanned and added to the collection.

"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."

The British Geological Survey (BGS) is a world-leading geological survey and global geoscience organisation, focused on public-good science for government and research to understand earth and environmental processes. We are the UK’s premier provider of objective and authoritative geoscientific data, information and knowledge to help society to use its natural resources responsibly, manage environmental change and be resilient to environmental hazards. For more information see: https://www.bgs.ac.uk/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. Most non-confidential boreholes link to a scan of the borehole record. For more information see: https://www.bgs.ac.uk/information-hub/borehole-recordsSOBI points are visible when zoomed in beyond scales of 1:175,000SOBI is also available on the BGS website via the GeoIndex or as a WMSFor more information contact: enquiries@bgs.ac.uk

Data from the British Geological Survey's GeoIndex Boreholes 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.

"The simplified texture classifications are derived from measured soil thicknesses taken from archive borehole records held by BGS (see the BGS Soil-sample Depth dataset in the map viewer: http://mapapps2.bgs.ac.uk/ukso/home.html?layers=SamplesDepth). The thicknesses are compared and collated with the expected engineering strength classification of their underlying soil-parent material type to show a map of distribution of the classes; expert judgment has been used to estimate a thickness class where borehole data is not available). Note that the map uses combinations of terms that refer to: Deep soils, Intermediate soils and Shallow soils (see table below). As a rule of thumb, these categories are based on the ability to manually dig (with a spade) without being hindered by a substrate that is too strong to excavate (i.e. layers of solid rock, dense gravel, or very stiff clays). An example of a deep soil would be one developed over unconsolidated, clayey Quaternary deposits, and an example of a shallow soil would be one found in areas underlain by chalk or limestone. Users should note that land management practices and natural weathering and accumulation (or erosion) processes of soil materials play a significant role in controlling soil thickness (it has not been possible to factor in these influences within the scope of this dataset) and so the classes shown in this dataset should be regarded as 'indicative'."

It is crucial that the engineered seals of boreholes in the vicinity of a deep storage facility remain effective for considerable timescales if the long-term geological containment of stored CO2 is to be effective. These timescales extend beyond those achievable by laboratory experiments or industrial experience. Study of the carbonation of natural Ca silicate hydrate (CSH) phases provides a useful insight into the alteration processes and evolution of cement phases over long-timescales more comparable with those considered in performance assessments. Samples from two such natural analogues in Northern Ireland have been compared with samples from laboratory experiments on the carbonation of Portland cement. Samples showed similar carbonation reaction processes even though the natural and experimental samples underwent carbonation under very different conditions and timescales. These included conversion of the CSH phases to CaCO3 and SiO2, and the formation of a well-defined reaction front. In laboratory experiments the reaction front is associated with localised Ca migration, localised matrix porosity increase, and localised shrinkage of the cement matrix with concomitant cracking. Behind the reaction front is a zone of CaCO3 precipitation that partly seals porosity. A broader and more porous/permeable reaction zone was created in the laboratory experiments compared to the natural samples, and it is possible that short-term experiments might not fully replicate slower, longer-term processes. That the natural samples had only undergone limited carbonation, even though they had been exposed to atmospheric CO2 or dissolved View the MathML sourceHCO3- in groundwater for several thousands of years, may indicate that the limited amounts of carbonate mineral formation may have protected the CSH phases from further reaction. doi:10.1016/j.apgeochem.2012.09.007. http://www.sciencedirect.com/science/article/pii/S0883292712002594.
