Canada has a series of large hydrocarbon basins with thick, organic-rich shales. Western Canada also contains the prolific and extensive Montney and Doig resource plays categorized primarily as tight sand and siltstone reservoirs. The risked shale gas in place for Canada is estimated at 2,413 trillion cubic feet, with 573 trillion cubic feet as risked, technically recoverable shale gas resource. In addition, estimated risked shale oil in place for Canada is about 162 billion barrels, with 8.8 billion barrels as risked, technically recoverable shale oil resource.
As new drilling occurs and more details is obtained on these large, emerging shale plays, the estimates of the size of their in place resources and their recoverability will change. The oil and gas industry in Canada was founded upon production of oil and natural gas from conventional reservoirs, because they are the easiest to get out of the ground. However, conventional reservoirs are the smallest portion of Canadas total oil and gas resources.
Ironically, what are referred to as unconventional reservoirs contain a far greater proportion of Canadas hydrocarbon resources. The terms conventional and unconventional actually refer to the reservoir rock quality because oil and gas cannot be distinguished. Industry needs to develop unconventional resources, such as tight oil, tight gas and shale gas, in order to have a continued supply of oil and gas now and into the future. Unconventional gas already accounts for more than 25% of the Canadian natural gas supply. Most of the activity directed at new production in Canada is unconventional so it is fair to say that unconventional has become conventional.
Currently, between Alberta and British Columbia over 175,000 wells have been stimulated using hydraulic fracturing. Canadian regulators and the natural gas industry are focused on the protection of surface and ground water and the mitigation of risk. All Canadian jurisdictions regulate the interface between water and the natural gas industry, and the application of evolving hydraulic fracturing techniques for unconventional gas development is no exception.
This report discusses about North American shale gas plays by giving the details of geological setting, resource estimate, reservoir properties, companies operating in that shale area, current activity, key company information and competitive landscape.
