Résumé

Deployment of carbon capture and storage on a large scale poses many challenges. One is the availability of reservoirs with suitable characteristics (high porosity and permeability, matched large emitters, etc.). Such a challenge might lead to the selection of reservoirs with relatively low porosity. In those environments, the rock matrix is often stiff and questions arise regarding the capabilities of seismic methods to monitor math formula injection. An illustrative modeling of seismic reflectivities within a hypothetical geological formation with physical properties equal to that of the low-porosity reservoir in the St. Lawrence Lowlands sedimentary basin, suggests that a math formula liquid-water contact is a potentially good seismic reflector despite a priori unfavorable conditions.
