X-ray micro- computed tomography image of Bentheimer sandstone

Lab Overview

The subsurface hydrophysics group is focused on gaining fundamental mechanistic understanding of fluid, solute, and colloid transport processes in heterogeneous porous and fractured media. The image above highlights the complexity of the pore space (black regions) that fluids navigate as they flow through the subsurface. Our approach often leverages in situ imaging—such as X-ray computed tomography, positron emission tomography, or optical imaging—combined with analytical, numerical, and data science methods to describe transport processes in these complex geologic systems across time and length scales. Due to the fundamental nature of this approach, and the ubiquity of fluid transport in porous media, this work has important applications across a range of environmental and geological processes including contaminant migration in the vadose zone, heat recovery in geothermal energy systems, bacteria transport in the subsurface, and carbon dioxide transport and immobilization in geologic carbon storage projects.
