Propane-based fracturing improves well performance in Canadian tight reservoirs ///

The McCully tight gas field in New Brunswick, Canada, is being developed by Corridor Resources and began producing gas from two wells in 2003. Full development occurred in 2007 with the startup of the McCully gas plant and tie-in to the Maritimes and Northeast pipeline. The unconventional nature of the reservoir requires the wells to be fracture stimulated to enable economic gas production. Prior to 2009, the preferred technique was to use water as the fracturing fluid. That year, fracture stimulations using gelled propane were performed in an attempt to improve fracture characteristics and flowback.
