In concert with the petroleum, continental dynamics and paleoenvironment and hydrogeology, the geophysics and remote sensing research group performs research on understanding earth structure, sedimentary basins, near surface environments/processes and process geomorphology on Earth and other planetary bodies.
Near Surface Geophysics
Near Surface Geophysics research focuses on imaging the top 100 m of the Earth’s surface to advance understanding of subsurface hydrogeological, geochemical and biological processes. Ares of interest include biogeophysics, hydrogeophysics, and paleoenvironmental change.
Biogophysics research is focused on integrating microbiological, geochemical and geophysical techniques to understand subsurface biogeochemical processes with applications to petroleum microbial systems, contaminated environments, bioremediation, microbial ecology, biogeochemical cycles and search for life in extreme environments.
Hydrogeophysics research is focused on using electrical geophysical techniques to evaluate NAPL impacted sites integrating hydrogeophysical data, improve understanding of groundwater/surface water interactions and using transient resistivity to track fluid movement.
Seismology: Physical properties of rocks and fluids can be obtained by analyzing various attributes of the seismic wavefield such as reflection and refraction arrival time, amplitudes, phase, frequency and curvature. Current research focuses on analyzing the three-component wavefield through velocity modeling, depth migration and attribute mapping to reconstruct the structure and stratigraphy of the subsurface at scales varying from ultra-shallow near-surface to ultra-deep crustal. Other research involve the development of rock physics models for reservoir characterization as well as biofilms in porous media.
Remote Sensing: Remote Sensing research involves analyses of data obtained about a study target without directly contacting the target. In addition to the study of potential fields (gravity and magnetics) and other subsurface techniques described above, active research based on surficial analyses using optical (visible through radar wavelength) geophysics based on laboratory, field, airborne, and spaceborne sensors is ongoing; research applications are diverse and include analyses of surface topography and composition, geochemistry, hydrocarbon exploration, structural geology, tectonics, volcanology, planetary geology, and process geomorphology.
