Research Assistant Professor, Department of Marine Geosciences - Rosenstiel School of Marine, Atmospheric, and Earth Science

Ralf J. Weger is an Assistant Professor in the Department of Marine Geosciences (MGS) at the University of Miami’s Rosesntiel School of Marine, Atmospheric, and Earth Science. He manages the Petrophysics Laboratory, CSL–Center for Carbonate Research. He received his Ph.D. in marine geology and geophysics from University of Miami in 2006. He focuses on quantitative pore- and rock-type parameters of carbonates and mixed siliciclastics, and their relationship to velocity and other physical properties. His main interest is petrophysical characterization of mixed carbonate–siliciclastic rocks.

Petrophysics of Carbonates:

  1. Assess the parameters controlling physical properties of carbonate (and mixed-carbonate-siliciclastic) rocks
  2. Design experiments quantify the influence of porosity and pore structure on acoustic velocity, resistivity, and permeability
  3. Test assumptions in rock physics theories that are used to interpret or predict rock properties from seismic and log data.
  4. Design experiments to evaluate rock-fluid interaction questions such as:
    a. do formation fluids interact with strata to strengthen or weaken the rocks?
    b. Does CO2 content in formation fluids change physical properties of rocks (e.g., permeability, porosity, acoustic velocity, an electrical resistivity).

Outcrop-to-Subsurface correlation in Unconventional Reservoirs:

  1. Characterize lithologic and petrophysical properties of mixed carbonate-siliciclastic outcrop samples
  2. Assess the factors controlling the distribution of the organic material in unconventional formations
  3. Use detailed outcrop analysis to correlate to and interpret subsurface data to answering questions regarding producibility (or injectability) of different unconventional rock facies.
