Summary(Plain Language Summary, not published)
The Utica Shale in the St. Lawrence Lowlands has a shale gas production potential, but shale gas exploration activities are currently suspended in Quebec. In 2012, the Geological Survey of Canada initiated a project in the St-Edouard area, 65 km south-west of Quebec City, to investigate the potential links between a deep shale gas formation and shallow aquifers. To support this multi-disciplinary study, borehole geophysical logging was carried out in 11 shallow boreholes drilled by the GSC ranging in depth from 30 - 150m. Natural gamma, resistivity, P and S wave velocities, fluid logging, optical and acoustic televiewing, and flow meter testing were used to assess lithological changes, structural features intersected by the wells, and identify presence of fractures transmitting fluid into the wells. This factual report presents the digital log data and figures of the log suites.
