Research Interests

Research interests are related to the deposition and diagenesis of carbonate rocks, and the application of carbonate geology to the understanding of petroleum reservoirs. Principles of carbonate diagenesis, and porosity and permeability evolution, are common themes.

Past diagenetic studies typically focused on the processes of diagenesis as determined from the petrography and geochemistry of the diagenetic products, and when possible, the actual diagenetic fluids. Over my career I have analyzed early fresh-water diagenesis and mineralogical stabilization, burial diagenesis in the presence of seawater, mass transfer and cementation in regional fresh-water aquifers, the formation of microporosity in limestones, the origin of dolomite, early compaction phenomena, the evolution of permeability with increased burial depth in the Cenozoic limestones of the modern Floridan aquifer system, and lateral variability in petrophysical properties of dolomites.

Current Work Includes:

1) Nature and evolution of pore systems in carbonate-rich unconventional reservoirs, specifically the Niobrara Formation in Colorado. As these are nano to micron in scale, much of the work involves using FIB-SEM to document the pores and spatial relationships (in 3D cubes). Core examinations and thin section work are used to establish contexts for the pore imaging.
2) Collaboration with Anthony J. Park of Sienna Geodynamics (http://www.sienna-geodynamics.com/index.html) on the forward modeling of diagenetic patterns in carbonates.
3) Exploration of self-organizing processes in sedimentary systems.
