Current Research and Scholarly Interests


Research
I am interested in modeling flow and transport in natural porous media. Application areas include reservoir simulation and subsurface CO2 sequestration. Current research activities include: (1) modeling unstable miscible and immiscible flows in heterogeneous formations, (2) developing multiscale formulations and scalable linear/nonlinear solution algorithms for multiphase flow in large-scale subsurface systems, and (3) developing stochastic approaches for quantifying the uncertainty associated with predictions of subsurface flow performance.

Teaching
I teach courses on multiphase flow in porous media and numerical reservoir simulation.

    Abstract

    A well-characterized set of large-scale laboratory experiments is presented, illustrating forced imbibition displacements in the presence of irreducible wetting phase saturation in a cylindrical, homogeneous Berea sandstone rock. Experiments are designed to operate in the regime of compact microscopic flows and large-scale viscous instability. The distribution of fluid phases during the flow process is visualized by high-resolution computed tomography imaging. Linear stability analysis and high-accuracy numerical simulations are employed to analyze the ability of macroscopic continuum equations to provide a consistent approximation of the displacement process. The validity of the equilibrium relative permeability functions, which form the basis for the continuum model, is fundamentally related to the stability of the displacement process. It is shown that not only is the stable flow regime modeled accurately by existing continuum models, but the onset of instability as well as the initial unstable modes are also determined with reasonable accuracy for unstable flows. However, the continuum model is found to be deficient in the case of fully developed unstable flows.
