AbstractThe Geological Survey of Canada is carrying out two projects to assess potential fluid migration pathways from deep (~2 km) shale or tight sand units to shallow aquifers in southern Quebec (St-Édouard area, St. Lawrence Lowlands) and in southern New Brunswick (Sussex area, McCully gas field). The geological and hydrogeological contexts of these study areas are very different. One of the main differences is the aquifer types, which are mainly composed of organic-rich black shales in St-Édouard and dominated by sandstone in the Sussex area. Also, while no shale gas well is in production in the St. Lawrence Lowlands, the McCully gas field has been in production since 2001. Because the intermediate zone, located between aquifers and reservoirs, is poorly known, these projects are using multi-source direct and indirect data including field geology, geophysics, geomechanics, hydrogeology and water and rock geochemistry to evaluate aquifer vulnerability.
