AbstractGeological Survey of Canada (GSC) research on shale gas and tight oil started in 2011 with a 4-year project on cap rock integrity in eastern Canada (Quebec, New Brunswick and Nova Scotia). In 2012, four new 4-year projects were implemented: development of new resource assessment methodology, geological characterization of shale reservoir, evaluation of groundwater risks related to drilling, and recording the potential for drilling-induced seismicity. The projects are supported under the GSC¿s Geoscience for New Energy Supply and Environmental Geoscience research programs. These projects were developed after significant internal considerations, national workshops and extensive bilateral discussions between the GSC and number of provincial departments of Natural Resources, Energy and Environment and oil and gas regulators. In the case of New Brunswick, two joint projects on the Frederick Brook Shale are currently active in the southern part of the province.

The evaluation of cap rock integrity project is currently in its 3rd year. In the first year, a synthesis of all pertinent geological and hydrogeological data was included in an eastern Canada GIS database, released as GSC Open File 7368. In 2012, a water well study was conducted over the McCully gas field area; water chemical compositions were measured and compared with the deep brine in the gas field, and samples were tested for dissolved methane in the groundwater. No methane was detected in the area of McCully development and water chemistry does not suggest connections. The results have been released in GSC Open File 7449. As of Fall 2013, development of a 3-D geological model over the McCully field is in progress as well as a detailed chemostratigraphic analysis of the Carboniferous shales.

A project to record the seismicity potentially-induced by hydraulic fracturing was initiated in Fall 2012 with the deployment of one seismograph station in the Moncton sub-basin. This station complemented the National Canadian Seismograph Network which has a detection level of about magnitude 2.0 in New Brunswick. For decades, including the last few years, southeastern NB has had a very low level of earthquake activity. Four additional stations were deployed in Fall 2013 to improve the detection threshold and location of earthquakes in southeastern NB. The data will serve to establish a base level of earthquake activity prior to a possible resumption of hydraulic fracturing in this area.
Summary(Plain Language Summary, not published)
Presentation of pan-canadian research on shale gas in the GNES and EG programs with a focus on activities in southern New Brunswick where a PERD project on cap rock integrity is active since 2011 and a new seismicity monitoring ecoEII project has been initiated last year.
