A joint Canada-USA standard for the geologic storage of carbon dioxide was announced last week by two Canadian organizations. The initial research for the project was done by the Saskatchewan-based International Performance Assessment Centre for Geologic Storage of Carbon Dioxide, which collaborated with the Toronto-based CSA Group to produce the final standard. The process included participation from a technical committee of more than 30 professionals representing industry, regulators, researchers and non-governmental organizations from both sides of the border.
The standard is primarily applicable to saline aquifers and depleted hydrocarbon reservoirs and could also be applied to storage associated with enhanced hydrocarbon recovery projects. It includes recommendations for the safer design, construction, operation, maintenance, and closure of storage sites. Also included are recommendations for the development of management documents, community engagement, risk assessment, and risk communication. More
Saskatchewan has been active in the carbon storage arena for over a decade. The Canadian oil producer Cenovus Energy (formerly EnCana) has been injecting CO2 into the province's Weyburn Oil Field since 2000. The CO2 for that project comes via pipeline from the Dakota Gasification Plant near Beulah in Mercer County, North Dakota. In addition, Shell Oil piloted CO2 injection into Saskatchewan's Midale Field in the 1980's, which Apache Canada continued in 2005.
More recently, the Saskatchewan-based Petroleum Technology Research Centre announced in September the completion of a 11,141 foot well to be used for testing the deep saline storage of carbon dioxide. A second observation well drilling project was scheduled to begin in October and is expected to be of a comparable depth. Both wells are part of a four-year research and monitoring project designed to demonstrate that storing carbon dioxide deep underground in a brine and sandstone water formation is a safe, workable solution to reduce greenhouse gases.
