The characterization of deep saline reservoir is an important step to evaluate the potential for CO2 storage in the St. Lawrence Lowlands in the Becancour area, Quebec. Due to the limited quantity of boreholes and seismic lines available in the area, accurate modeling of stratigraphic units is not realistic. In this study, we kriged the tops of the geological formations recorded in the depth domain at 11 boreholes using an external trend interpreted from 2D seismic horizons picked in two-way. Results obtained on the geological horizons show a good compromise between the areal structure expressed by the variograms and the external trend evaluated on the modeled horizons.

The St. Lawrence Lowlands platform and frontal thrust slices of the Appalachian belt are prospective for CO2 storage in the province of Quebec. The thick (1,500 to 3,000 meters) sedimentary succession hosts two types of reservoirs: deep saline aquifers in the platform and gas reservoirs in the fold-thrust belt. The Potsdam, Beekmantown and Trenton groups are identified as the potential reservoir formations in the St. Lawrence Lowlands sedimentary succession. A preliminary analysis of selected storage sites is used to evaluate theoretical and effective capacities for CO2 storage at the basin and reservoir scales.
