Migration and storage characteristics of supercritical CO2 in anisotropic sandstones with clay interlayers based on X-CT experiments

To date, many laboratory-based core scale (i.e. flooding) studies have focused on relatively homogeneous rock samples (e.g. Berea sandstone) to study the migration characteristics of supercritical carbon dioxide (SC-CO2) and evaluate these rocks for their potential geological CO2 storage. Clay interlayers with low porosity and permeability developed in sandstones are often encountered in target reservoirs and can have an obvious influence on the...
