My research focus is on dispersion phenomena in porous systems such as hydrocarbon reservoirs and brine aquifers. Natural rocks in these systems are among the most fascinating and complicated porous systems. This interest has led me to work on different applications in energy and the environment. Some examples are:

Shale gas: These types of reservoirs are categorized as unconventional reservoirs because of gas desorption and flow in nanopore (10-9 m) structures. At the nanoscale most continuum equations, e.g. Darcy equation, may not be valid. Characterizing nanopores and obtaining new sets of governing equations to describe gas desorption from nanopores and gas flow in nanopores are my major foci for shale-gas reservoirs.

CO2 injection up-scaling: The process of CO2 injection into geological formations, e.g. EOR, EGR, and sequestration, is a complex process that needs a potpourri of multi-physics, e.g. diffusion, convection, and chemical reaction. Current research relates these processes at the pore scale to meaningful macroscale coefficients to be used in commercial simulators [3].

Application of nanotechnology in rock characterization: Using atomic force microscopy (AFM) to detect nanopores and different materials in shale-gas systems and seal beds. AFM is a nondestructive technique formapping topologies at the molecular scale.
