A core scanning dataset from the BHA-101 drill core that was drilled onshore at the Ince Marshes site near the village of Elton, Cheshire, UK as part of the UK Geoenergy Observatories (UKGEOS) Cheshire ground investigation funded by UKRI/NERC. This core scanning dataset pack contains high-resolution optical and radiographic images, X-ray fluorescence (XRF) and physical property downcore point measurements on core from 71.12 m to 121.1 m (Sherwood Sandstone Group) obtained at the Core Scanning Facility (CSF) at the British Geological Survey (BGS).

IDA272269 Methane and CO2 gas concentrations and stable isotope analyses of cutting samples from GGA05 and GGA08 boreholes of the Glasgow UKGEOS facility. Cutting samples were collected approximately every 3m depth in gas tight isojars by the BGS. Geochemical gas analyses was carried out at the Scottish Universities Environmental Research Centre (SUERC) and consisted of bulk concentration analysis using gas chromatography; followed by δ13CCH4, δ13CCO2, and δD stable isotope analyses on a methane combustion line (full methods attached). This data was collected to investigate the variability of gas fingerprints with depth within the Glasgow coal mine workings, and unmined Carboniferous coal measures. Samples and data are derived from the UK Geoenergy Observatories Programme funded by the UKRI Natural Environment Research Council and delivered by the British Geological Survey.

A comprehensive core scanning dataset from the Prees-2C borehole. This borehole was drilled onshore in the Cheshire Basin, Shropshire, UK, in November and December 2020 as part of the JET project (Integrated understanding of Early Jurassic Earth system and timescale - https://gtr.ukri.org/projects?ref=NE 2FN018508 2F1) and principally funded by the ICDP, NERC, and DFG. The approximately 620 m-long Early Jurassic core succession (>99% recovery) mainly comprises mudstone, limestone, and siltstone. The core scanning dataset contains optical images, radiographic images, geophysical and geochemical property data obtained using a Geotek rotating X-ray computed tomography core scanner (RXCT), a Geotek multi-sensor core logger (MSCL-S) and a Cox Analytical Systems XRF core scanner (Itrax MC) at the Core Scanning Facility (CSF) at the British Geological Survey (BGS).

Porosity of core samples SSK111464 (sandstone) and SSK111465 (shale) calculated using backscatter electron SEM images of carbon coated thin sections processed in ImageJ Fiji software. 85 images of SSK111464 (sandstone) used and 74 images of SSK111465 (shale) at various magnifications. Core samples from UKGEOS Glasgow Observatory, borehole GGC01. Samples and data are derived from the UK Geoenergy Observatories Programme funded by the UKRI Natural Environment Research Council and delivered by the British Geological Survey.

The borehole information pack from borehole TH0410 at the UK GeoEnergy Observatories (UKGEOS) Cheshire facility. This release from the British Geological Survey (BGS) contains a borehole schematic, borehole metadata, a report from the drilling contractors, geophysical wireline logs, and an index to samples collected from the borehole, which are archived in the National Geological Repository at BGS Keyworth. No core scanning data is available for this borehole and the core has been disposed of.

The final borehole information pack from the TH0424 Ground Investigation Borehole drilled as part of the UK Geoenergy Observatories (UKGEOS) Cheshire facility. TH0424 was drilled to TD of 101 m between the 08-Nov-2021 and 30 Nov-2021. Drill core was collected from 2 m – 101 m with 100 mm diameter. This final data release pack from BGS contains composite and digital wireline logs alongside daily driller's borehole records, sedimentary and discontinuity logging and core analysis data. This information pack also contains the Initial and additional Core Scanning datasets from the BGS Core Scanning Facility (https://doi.org/10.5285/b06d44e6-324d-4e19-bf78-a4520b9b87c8 and https://doi.org/10.5285/381e9664-0f43-4e4c-90ae-1b16ba83681b).

These images were acquired using micro computed tomographic imaging of 4 sandstone plugs taken at various depths in the Glasgow UKGEOS borehole GGC01. GG496 (170.07 m), GG497 (168.66 m), GG498 (73.37 m) and GG499 (135.06 m). These samples are further detailed and analysed in the following article: http://dx.doi.org/10.1144/petgeo2020-092.

This data pack contains information from geotechnical and contaminated land investigations carried out at potential sites for the development of the UK Geoenergy Observatory in Cheshire. Following these investigations, a decision was made to move the proposed observatory to Thornton Science Park. None of the sites discussed in this data pack are in scope for development as part of the Cheshire Observatory. In total 16 holes were drilled using a variety of techniques. The only hole to be drilled using rotary coring was BHA-101. This borehole was cored extensively and logged with wireline geophysical tools. As such this is the main focus of the data pack. BHA-101 was drilled to TD of 121.2 m between 19-Nov-2020 and 09-Dec-2020. Drill core was collected from 51 m – 121 mm with 100 mm diameter. This initial data release pack from BGS contains composite and digital wireline logs alongside daily driller's borehole records.

The data release includes surface and groundwater chemistry data from 99 samples (33 surface water, 60 groundwater, and 6 groundwater duplicates) collected during the baseline water monitoring at the UK Geoenergy Observatories (UKGEOS) Glasgow facility. This release from the British Geological Survey (BGS) covers surface and groundwater samples collected between 22 June 2021 and 28 January 2022 from 6 surface water sites, 5 mine water boreholes, and 5 environmental monitoring boreholes. The samples were then analysed for the concentrations of selected parameters at BGS and other laboratories. It contains a report and 2 data sheets GroundWaterChemData2 and SurfaceWaterChemData3.

An additional core scanning dataset from the TH0424 drill core that was drilled onshore at Thornton Science Park, Cheshire, UK as part of the UK Geoenergy Observatories (UKGEOS) Cheshire ground investigation funded by UKRI/NERC. The approximately 100 m long core succession comprises the Sherwood Sandstone Group. This additional core scanning dataset pack contains high-resolution optical images and X-ray fluorescence (XRF) downcore point measurements obtained using a Geotek Core Workstation (MSCL-XYZ) at the Core Scanning Facility (CSF) at the British Geological Survey (BGS).
