Research Interests

My research program focuses on understanding the mechanics and flow behavior of mudstones. I am particularly interested in subsurface fluid flow and controls on permeability and compressibility in marine sediments. In addition, I also study transport behavior and diagenesis in shale gas reservoirs. My group uses field samples and data and employs a suite of laboratory techniques to pursue these research interests including sedimentological and geotechnical experimentation (grain size, Atterberg Limits, uniaxial consolidation). We also use imaging techniques in order to analyze microstructures of the mudstones.
Sediment Mechanics:
Stresses and pressures in the subsurface and subsurface fluid flow as a result are of high interest to my research group. We seek to understand how particle size, particle shape, (clay) mineralogy, and microorganisms affect the mechanical and transport behavior of mudstones and how these physical properties are related to each other. Especially the study of microorganisms and their role in early diagenesis and subsequent influence on reservoir development is a new research project. My research group uses sedimentological experimentation such as particle size analyses, Atterberg Limits, petrographical analyses, and nano- to microscale imaging to characterize sediments and geotechnical experimentation like resedimentation tests and uniaxial compression tests to deform natural mudstones simulating the natural processes of deposition and burial. By preparing and compressing natural mudstones in the laboratory under controlled conditions using the resedimentation technique, we can perform systematic studies to understand fundamental behavior, e.g. how the addition of silt-sized particles or bacteria affect the compressibility, microstructure, and permeability.

Mudrocks/Unconventional reservoirs:An important aspect of my research involves studying mass transport behavior and diagenesis in tight mudrocks such as shale gas reservoirs. One recent project is on the effect of diagenesis on rock consolidation behavior. This information is critical for basin modeling but also for petroleum systems analyses, in which consolidation models are used to predict reservoir and seal quality through time. My group uses field samples and a suite of sedimentology and geomechanical laboratory techniques such as petrographical analyses and Scanning Electron Microscopy to analyze microstructures and flow behavior of mudrocks.
