The pore geometry of natural sandstone (digital rock)
was obtained using high-resolution CT device (left), and CO2-water-oil
behavior within the heterogeneous pores were calculated using
three-phase lattice-Boltzmann model (right). The greater detail
provided by the digital rock model simulation can help to identify the
relevant processes of CO2 movement in oil reservoir and the rock's
potential for CO2 storage in natural rock.
