Summer Internships, Mobil Exploration and Producing US, Inc., Denver, Colorado, Alpine, Wyoming, and Dallas, Texas, 1991, 1993. Exploration geology, integrating well logs with field stratigraphic investigation of a carbonate gas reservoir in the western Wyoming fold-thrust belt. In second summer, explored for accumulations of hydrocarbons in Lower Cretaceous carbonate strata in the Gulf of Mexico, integrating sequence-stratigraphic concepts with petrographic studies of borehole cuttings, well logs, and seismic data. Summer Internship, 1987, Shell Western Exploration and Production Inc. (SWEPI), Houston, 1988. Performed subsurface analogue studies of two Silurian and Devonian carbonate reservoirs on the central basin platform in western Texas.
