AbstractCarbon capture and storage (CCS) has been identified as a priority issue within the context of the North American climate change and energy collaboration. An important aspect of CCS is the need to improve public confidence in long-term geological storage of CO2. A key to developing confidence for the longer term is a demonstration of safe and expected storage behaviour in the short term. Two primary concerns of the public and government regulatory bodies are the potential for induced seismicity and for CO2 leakage. To alleviate these concerns, storage monitoring is critical in demonstrating that the subsurface CO2 plume is behaving as expected, and that induced microseismic or seismic activity is being closely monitored. The Aquistore CO2 Storage Project is a multi-year research and monitoring project to demonstrate that storing CO2 deep underground is a safe and workable solution to help reduce greenhouse gas emissions to the atmosphere. The Geological Survey of Canada's studies within the project are focused on the development of improved monitoring methodologies and a better understanding of the relationship between CO2 injection and induced seismicity.
A total of 60 ktonnes of CO2 were injected at the Aquistore site in the first year following initial injection in April-2015. Injection is occurring within a saline formation at a depth of 3150-3350m. In the first 4 months of 2016, CO2 was injected at an average rate of ~400 tonnes/day. Passive seismic monitoring at the site which began in 2012 has not identified any seismicity associated with the injection process. The first time-lapse 3D seismic surveys were completed in February of 2016 and will provide images of the CO2 plume in the subsurface.
Summary(Plain Language Summary, not published)
The environmental geoscience program is a federal research program that aims to provide Canadians with advanced scientific information to differentiate the effects of the development of natural resources on the environment of those of natural processes. Following this mandate, the development of new geoscientific approaches is used to support the developement and responsible use of Canada's natural resources by making informed decisions while protecting Canadians and their environment. Advancing scientific understanding about natural resources development will inform policy makers and have direct implications on future decisions. To increase the program visibility, a public session was offered in May 2016 to the Earth Science Sector and other key partners from Natural Resources Canada. All the information presented during the public session is included in this Open File.
