Mechanism-Based Investigation of Carbon Dioxide Storage in Saline Aquifers Through Relative Permeability Experiments

One of the most significant current discussions in developed countries is the concern dealing with the emission of anthropogenic Green House Gas(GHG). Carbon Capture and Storage (CCS) is one of the most short- to mid-term trusted remedy method for reducing hazardous acid gas produced in industrial plants. Although deep saline aquifers are good choices in storage of CO2, depleted gas and oil reservoirs could be suitable candidates for either carbon storage or as one of the enhanced gas/oil recovery methods. For a CCS project to be successful, it is essential to evaluate reservoir storage capacity, injectivity, and containment as the chief parameters controlling it. However, so far there have been little investigation, especially on injectivity. This factor is directly controlled by different rock/fluid properties such as absolute and relative permeability. Hence, measurement of relative permeability and end point values are vital in understanding fluid distribution characteristics inside the porous medium.
