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.
