Assessment of Pressure Interference in Alberta's Proposed Carbon Storage Hubs

This presentation assesses the magnitude and distance of elevated pressure that an injection site can impose on neighbouring projects resulting in potential for competitive injection. The results of initial 1D isothermal single-phase and multi-phase numerical simulation models are compared. Regional geologic and hydrogeologic mapping was completed and used as the basis to construct a regional-scale numerical model that was calibrated to replicate actual field pressure response at the Quest CCS site, a Shell operated site that began injecting CO2 in 2015.
