Abstract
The Containment and Monitoring Institute (CaMI) of CMC, in collaboration with the University of Calgary, operates a comprehensive CO2 injection and storage program at its Field Research Station (FRS) in Newell County, Southern Alberta, Canada. We are injecting a small amount of CO2 (48.4 tonnes at the end of 2021) at shallow depth (300m) to simulate a leakage from a deep CO2 storage reservoir. The controlled amount of injected CO2 is used to test and develop monitoring technologies, and to estimate CO2 detection threshold for the different tools. We will give a brief overview of the broad range of geophysical and geochemical monitoring technologies tested at the site, including distributed acoustic sensing (DAS), continuous seismic monitoring (broadband stations, surface and borehole geophones), and active seismic surveys. We will focus on the results of vertical seismic profile (VSP) time-lapse monitoring and electrical resistivity tomography (ERT) semi-continuous monitoring. We will demonstrate their detection thresholds (few tonnes for the ERT, few 10’s of tonnes for the VSP) and how they can be used as an early warning tool to detect loss of containment of deep large scale CO2 storage sites.
