Research Abstract

Carbon dioxide (CO_2) is injected into geological formations to mitigate climate change. First, CO_2 displaces brine which fills pore space of porous rock. This process is strongly influenced by capillarity, buoyancy and viscous shear stress. Next, brine displaces CO_2 again, but some fraction of CO_2 would be trapped in porous rock because of capillarity. Then trapped CO_2 bubbles would be solved into the brine. In a reservoir scale, dissolution of CO_2 into the brine is limited by the natural convection due to the density differences between unsaturated and saturated brine with CO_2. We experimentally investigated these processes in a pore scale by means of X-ray computer tomography. To predict long-term fate of the injected CO_2, novel mathematical models were developed for each process.
