AbstractThe research objectives of the Aquistore CO2 storage project are to design, adapt, and test non-seismic monitoring methods for measurement, and verification of CO2 storage, and to integrate data to determine subsurface fluid distributions, pressure changes and associated surface deformation. The test area is located west of the Boundary Dam Power Station in southeastern Saskatchewan, Canada. The targeted CO2 injection zones are within the Winnipeg and Deadwood formations located at < 3000 m depth. An array of monitoring technique was employed in the study area including advanced satellite Differential Interferometric Synthetic Aperture Radar (DInSAR) technique, GPS, tiltmeters and piezometers. Ground deformation maps have been calculated using Multidimensional Small Baseline Subset (MSBAS) technique from 134 RADARSAT-2 images, from five different beams, acquired during 20120612-20140706. MSBAS results indicate slow ground deformation up to 1 cm/year not related to CO2 injection but caused by various natural and anthropogenic causes. © 2014 SPIE.
