Abstract

Within this Phase I of the International Weyburn CO2 Sequestration Project results of regional seismic / well log investigations are presented from a region of around 100 km radius of the storage site in Southern Saskatchewan (Figure 1, 1a). The objective is to answer the following question: Do the tectonic, petrophysical and rheological properties of the sedimentary fill guarantee the permanent storage (̃10000 years) of CO2 in the region? To answer the question both regional and detailed tectonic setting as well as the history of the tectonic activities of the subsurface were investigated. A number of prominent fault systems were recognized. Some of these are the consequence of the original tectonic development of the region. A number of them were created by the dissolution of the salts of the underlying Devonian Prairie Evaporate formation. Several of these anomalous zone were reactivated a number of times, some as recently as Mid-Cretaceous times.
