Summary(Plain Language Summary, not published)
The Geological Survey of Canada (GSC) is investigating the vulnerability of shallow aquifers to unconventional gas development in the Sussex area, New Brunswick. To support the project, downhole geophysical logs were collected in 2016 in 10 GSC-drilled observation wells (50 to 80 m in depth) to better understand the in situ lithological, geomechanical, and hydrogeological properties of the near-surface bedrock. The suite of logs included natural gamma and gamma-gamma density, televiewer imagery (optical and acoustic), acoustic logs to compute compressional (P-) and shear (S-) wave velocities, and fluid logs (temperature, conductivity, flow). Logs were interpreted alongside GSC core and cuttings descriptions. This report summarises the downhole geophysical data acquisition and analyses, and provides log suites and digital data in appendices.
