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 and freshwater aquifers. Principles of carbonate diagenesis, and porosity and permeability evolution, are common themes.

Diagenetic studies typically focus on the processes of diagenesis as determined from the petrography and geochemistry of the diagenetic products, and when possible, the actual diagenetic fluids. Past work includes analysis of 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, and the evolution of permeability with increased burial depth in the Cenozoic limestones of the modern Floridan aquifer system.

Current work includes:

(1) Collaboration with Anthony J. Park of Sienna Geodynamics (http://www.sienna-geodynamics.com/index.html) on the forward modeling of diagenetic patterns in carbonates.

(2) Work with Dr. Matthew Pranter (http://spot.colorado.edu/~pranter/) that involves the analysis of variability in dolomites (AVID). This is an industry-supported effort to characterize and quantify lateral reservoir-scale heterogeneity (petrophysical, geochemical, etc.) within carbonate reservoirs using outcrop analogs. Related to this project, we are exploring the potential of self-organizing phenomena to impart predictable periodic patterns in the attributes of dolostones.

(3) Analysis of the impact of ocean acidification (driven by rising global CO2) on marine cementation and erosion of tropical reefs. This is an ongoing collaboration with Derek Manzello (Univ. of Miami), Joan Kleypas (NCAR), and Mark Eakin (NOAA).

(4) Assisting Dr. Frank Barnes, CU Dept. of Electrical Engineering, with the identification of potential geological repositories for compressed air energy storage (CAES) in Colorado. This technology effectively stores wind-generated energy until needed.
