AbstractCarbon Capture and Storage (CCS) has been identified as a priority issue within the context of the North American Climate Change and Energy Collaboration and Mission Innovation. 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 107 ktonnes of CO2 were injected at the Aquistore site from April-2015 to Jan-2017. Injection is occurring within a saline formation at a depth of 3150-3350 m. 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 conducted in February and November of 2016 when the cumulative injected quantity of CO2 was 36 ktonnes and 105 ktonnes, respectively. The resultant time-lapse seismic images show how the CO2 plume is partitioned vertically within the reservoir and how it is spreading laterally. The seismic observations indicate that the initial geological model used for CO2 flow simulations will have to be modified.
