Characterization of the Aquistore CO2 project storage site, Saskatchewan, Canada.

Aquistore is a new integrated Carbon Capture and Storage demonstration project in southeastern Saskatchewan, Canada. An extensive geological, geophysical, petrophysical, hydrogeological, and geochemical characterization program was undertaken using both pre-existing and newly-acquired data at this site. Data were assembled into several geological models that were used to support planning and permitting of the project. Carbon dioxide will be injected into a permeable sandstone interval approximately 150m thick using a newly-drilled 3400m deep injection well and monitored, in part, using a new 3400m deep instrumented observation well that is 150m away from the injection well. All of the integrated characterization work at the site thus far indicates strongly favorable conditions for geological CO2 storage in the subsurface at Aquistore.
