PERMEABILITY EVOLUTION IN FRACTURED ROCK IN RESPONSE TO MECHANICAL AND CHEMICAL PROCESSES
Summary Large-scale carbon capture and sequestration (CCS) projects are required to substantially reduce greenhouse gas emissions. The large rate and volume of injection induce pressure and stress gradients within the formation that could activate existing fractures and faults, or drive new fractures through the caprock. In addition, over longer periods of time, geochemical processes lead to evolution in the porosity and permeability of the storage domain. These processes involve coupling over multiple scales and require development of appropriate simulation capabilities. We present the results of investigations using two classes of computational tool: Distinct Element Methods and Boundary Element Methods. We present several demonstration applications of these codes to CO2 injection scenarios. These examples highlight the advantages of explicitly including the geomechanical response of each interface within the formation.
