| Abstract | The Geological Survey of Canada's deep borehole test site at the Bells Corners Borehole Calibration Facility in Ottawa, Ontario, has been in use since the 1980's for the development and calibration of
geophysical logging instrumentation. Cores from six deep boreholes (up to 300 m) are preserved and remain available for research purposes. In 2019, the facility underwent repairs to reopen deep boreholes, replace surface casings, and install
atmospheric monitoring equipment. This report documents new laboratory core testing and downhole geophysical logs collected in borehole BC81-2, the most frequently logged of the boreholes at the facility. Core data sets include physical, mechanical,
and hydraulic properties, nuclear magnetic resonance, and complex resistivity measurements. The downhole log suite includes televiewer imagery (optical and acoustic), total gamma, full waveform sonic, and fluid measurements (high resolution
temperature, conductivity, and flow meter measurements). Digital data are provided in appendices. These data sets support ongoing collaborations at the Facility across a variety of disciplines for geological exploration, geoengineering, and
hydrogeological research. |
| Summary | (Plain Language Summary, not published)
The Bells Corners Borehole Calibration Facility was developed by the Geological Survey of Canada (GSC) in the late 1970's in Ottawa, Ontario. The
Facility played a significant role in the advancement of Canadian geophysical logging instrumentation for exploration, and continues to provide reference datasets for the calibration of industry, government, and academia's logging tools. In recent
years, interest in the Facility is becoming more multi-disciplinary. The need for monitored deep borehole sites in Canada is increasingly important for long-term research into groundwater flow through fractured bedrock. Beginning in 2019, the GSC in
collaboration with CanmetMINING and CanmetENERGY, carried out testing on existing rock cores and collected new borehole geophysical logs to modernize the calibration datasets. The results support a broadening scope of research at the Facility in
geological exploration, geoengineering, and hydrogeological sectors. |
