Performed geologic (non-hydrologic) work in the following states and provinces:
Types of Geologic Work
The following content shows types of geology work that I have done, with one or more examples for each type. The list is not exhaustive and the examples are not all-inclusive.
Explored for petroleum in Colorado (Denver-Julesburg Basin, NW Colorado, Colorado Plateau), Wyoming (DJ Basin), Utah, Nevada, Illinois, Saskatchewan, and Alberta for a major oil company. This work included well log interpretation, surface and subsurface geologic mapping, stratigraphy, hydrodynamic analysis of petroleum systems, and well site operations.
Petroleum Reservoir Analysis
Reservoir mapping, DST pressure analysis, reserve calculations.
Assessed earthquake hazard at a proposed mine site (Montana).
Slope Stability and Landslide Hazard
Estimated slope stability at proposed real estate subdivisions (Montana).
Served as expert witness on the effect of irrigation on landsliding and testified in court (Montana).
Assessed the stability of slopes near a proposed mine in a mountainous area (Montana).
Snow Avalanche Hazard
Assessed snow avalanche hazard along an access road at a proposed mine in a mountain valley (Montana).
Coal Resource Assessment
Assessed value of coal resources on a ranch (Montana).
Environmental compliance assessment of coal company properties (Louisiana, Texas).
Performed the geologic parts of an environmental assessment for a subsurface platinum/palladium mine (slope stability, earthquake hazard, snow avalanche hazard.
Performed a coal resource assessment on a ranch in Montana.
Statistics in Geology
Performed statistical analyses of stable isotope data on methane from different geological provinces in California. Press the button 🔳 to see "California Methane Stable Isotope Data Analysis."
Published paper on "Probability of Anomalies on Contour Maps."
Performed a statistical analysis to see if sub-species of a fossil species were significantly different. (Honors thesis for geology bachelors degree.)
