| Abstract | Objectives of the Aquistore CO2 storage project are to design, adapt, and test non-seismic monitoring methods that have not been systematically utilized to date for monitoring CO2 storage, and to
integrate the data from these various monitoring tools to obtain quantitative estimates of the change in subsurface fluid distributions, pressure changes and associated surface deformation. Since spring of 2012 Radarsat-2 data from five beams
(ascending and descending Spotlight, Wide UltraFine and Fine Quad-Pol) was regularly (with the individual frequency of 24 days) collected and used for calculation of ground deformation time series over the Aquistore CO2 storage site located in SE
Saskatchewan. The initial InSAR analysis revealed slow ground deformation not related to CO2 re-injection but caused by various natural and anthropogenic processes - snow melting, surface moisture variation, ground and surface water level changes and
post-mining activities. In this work we provide updated results based on over one hundred RADARSAT-2 images acquired during May 2012 - May 2013. |
| Summary | (Plain Language Summary, not published)
Objectives of the Aquistore CO2 storage project are to design, adapt, and test non-seismic monitoring methods that have not been systematically utilized
to date for monitoring CO2 storage, and to integrate the data from these various monitoring tools to obtain quantitative estimates of the change in subsurface fluid distributions, pressure changes and associated surface deformation. This work
demonstrates preliminary deformation map for Aquistore CO2 injection site located near city of Estevan in Saskatchewan, Canada, and produced from satellite measurements. It is anticipated that CO2 injection will produce noticeable ground deformation
that may, if large enough, affect infrastructure. Satellite measurements presented here contribute to the larger study of monitoring of impact of CO2 injection on the environment. |
