GGC01 cored, seismic monitoring borehole – initial data release

Summary This report gives a short overview of information related to the initial data release for GGC01. The cored, seismic monitoring borehole GGC01 (BGS SOBI number NS66SW BJ 3754) was drilled between 19 November and 12 December 2018 producing a core of 102 mm diameter. The borehole was wireline logged in December 2018 and a string of 5 seismometers were installed in February 2019. Contributions to this report and the data acquired are as follows: Vanessa Starcher: Technical overview, wireline log data acquisition Kirsty Shorter: Fluid and geomicrobiology samples, tracer information, field measurements, photo metadata Hugh Barron: On-site core and data acquisition, initial geological interpretation Joel Burkin; Geomicrobiology samples, on site core management and initial geological interpretation Jack Elsome: Fluid and geomicrobiology samples Mark Fellgett: Wireline log data checking and documentation Andy Kingdon: Wireline log data checking and documentation Megan Barnett: Geomicrobiology samples Alison Monaghan: Coordinating initial data pack, initial geological interpretation IMPORTANT – Note that all borehole depths given in the initial data release are based on the drillers log dataset (excepting wireline data). Borehole depths will be subject to minor change once non-recovery intervals are assigned. Borehole and sample depths will be revised in the final borehole data pack so that core scans, wireline logs and borehole logs/samples are consistent

UK Geoenergy Observatories Glasgow: GGC01 cored, seismic monitoring borehole – final data release

This report provides an overview of information contained in the final data release for the UK Geoenergy Observatories Glasgow borehole GGC01. This final data release supersedes the initial and intermediate data releases (Starcher et al. 2019; Kearsey et al. 2019). It includes additional information on core scan data and core-wireline depth integration. The cored, seismic monitoring borehole GGC01 (BGS SOBI number NS66SW BJ 3754, BGS ID 20650619) was drilled between 19 November and 12 December 2018 producing a core of 102 mm diameter. The borehole was wireline logged in December 2018 and a string of 5 seismometers were installed in February 2019. The core was transported to the National Geological Repository (NGR) at BGS Keyworth and was curated into 1 m core boxes. State-of-the-art core scanners have been used to collect along core datasets. This final data release includes optical images (whole core and slabbed core), radiographic images, MSCL-S (geophysical), NIR and XRF (mineralogical and chemical) core scan data. Also included in this final release is the material from the previous releases including sedimentary, discontinuity and engineering logs, wireline/geophysical downhole logs, drillers’ logs and sample information

UK Geoenergy Observatories Glasgow: GGC01 cored, seismic monitoring borehole – intermediate data release

This report gives an overview of information related to an intermediate data release of the borehole information pack for UK Geoenergy Observatories: Glasgow borehole GGC01. The cored, seismic monitoring borehole GGC01 (BGS SOBI number NS66SW BJ 3754, BGS ID 20650619) was drilled between 19 November and 12 December 2018 producing a core of 102 mm diameter. The borehole was wireline logged in December 2018 and a string of 5 seismometers were installed in February 2019. The core was transported to the National Geological Repository (NGR) at BGS Keyworth and was curated into 1 m core boxes. State-of-the-art core scanners are being used to collect radiographic, CT, optical images, geophysical log and XRF along core datasets. Optical images and radiographic images are included in the intermediate release. Also included are sedimentary, discontinuity and engineering log
