Experimental and Numerical Study of Gas-Liquid Displacements in Flow Cells, With Application to Carbon Dioxide Sequestration in Brine Fields

In this paper experimental and computational modeling methods for studying viscous fingering phenomena occurring during underground CO₂ sequestration were developed. In the experiment, the displacement of two immiscible fluids in a lattice-like flow cell was studied. The flow pattern during the displacement was analyzed, and the residual saturation of the displaced fluid was measured. Numerical simulations of the experimental flow cell were performed. The numerical simulation results are compared with the experimental data good agreement was observed.
