There are currently 15 large-scale carbon capture and storage (CCS) projects and multiple pilot injection projects operating across the world. A critical challenge for successful CCS programs is to reliably and economically predict long-term behavior of CO2 in potential storage reservoirs. As with hydrocarbon reservoirs, assessment of CO2 storage reservoirs requires integration of several disciplines and multiple data sets. Geologic conceptual modeling, well-log analysis, petrophysics and rock-physics modeling, and seismic reservoir characterization provide important foundational data. Geochemical understanding of interactions among rock, water, and CO2, fluid-flow simulations of CO2 injection, and structural and geomechanical analysis...
