Integrated Tectonic and Petrophysical Investigation of the Williston Basin Sediments in and around the Weyburn CO2 Sequestration Reservoir, Canada (Part 2 - Petrophysical Considerations)

The successful long-term underground storage of CO2 requires a stable and permanently sealed storage site. In search of this facility, a two phase, comprehensive study investigated the tectonic setting and history as well as the petrophysical properties of the Weyburn reservoir in the Williston basin of southern Saskatchewan. Within the first part, small scale structural disturbances (i.e. faults with small offsets/local flexures) have been identified above the reservoir and in zones of the overlying seal. The preliminary results of the second part, the petrophysical study of some of these anomalous are reported here.
