WGI has extensive experience in the application of surface and borehole geophysical techniques for fracture detection. Staff have unique experience (in collaboration with the G360 group at the University of Guelph) developing innovative high sensitivity temperature logging in lined boreholes, Active Line Source (ALS) testing and the application of the Temperature Vector Probe (TVP) to characterize ambient groundwater flow in fractured rock. Combined with standard rock borehole geophysical logging, core logs, standard (flow meter) and innovative (FLUTe profiling) the data is used to design multi-level installations for testing and monitoring.
