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. (click here for the full permeability data from west-central Florida).
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
(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
