Description
Understanding the migration behavior of injected CO₂ within subsurface reservoirs is critical for the safe and efficient deployment of carbon capture and storage (CCS) technologies. While most laboratory-scale studies assume predominantly one-dimensional flow, actual reservoirs exhibit complex plume dynamics driven by buoyancy, permeability anisotropy, and vertical–horizontal connectivity. This study presents a systematic experimental investigation of horizontal versus vertical CO₂ plume movement using a high-pressure core flooding apparatus and reservoir cores cut with varying thicknesses and orientations. By comparing flow behavior in horizontally and vertically oriented cores, the experiments isolate the relative influence of gravitational segregation, viscous forces, and capillary effects on CO₂ migration. Measurements of pressure drop, saturation evolution, and breakthrough behavior are used to quantify directional differences in plume advancement and spreading. The results demonstrate how core geometry and orientation strongly influence CO₂ mobility and plume stability, providing insights into vertical leakage risks, lateral plume extent, and storage efficiency. This work bridges the gap between idealized laboratory experiments and field-scale reservoir behavior, enabling improved interpretation of CO₂ injection tests and more reliable prediction of plume evolution in heterogeneous formations.
