PROFESSIONAL EXPERIENCE

Marathon Oil Company - Scientist                                          1998 - 2000
Team leader of a group that focused on surfactant improved oil recovery via wettability
alteration at Yates Field, West Texas that resulted in 246 MBO incremental. Acted as
the liaison between laboratory personnel at the Littleton office and field personnel
responsible for surfactant application in the field. Collaborated with GeoQuest
developers to refine the Eclipse 200 surfactant simulator to include wettability
alteration. Applied this modified Eclipse simulator to model core-scale experiments and
field-scale surfactant flooding. Performed 3D reservoir characterization and model
construction of Camden Hills Field, Gulf of Mexico, and Central Brae Field, North Sea,
using (RC)2 geostatistical software. History matching and production scheduling of
Tchatamba South Field, offshore Gabon, using Eclipse. Simulation of infiltration of
produced water in West Texas using VS2DT, a variably saturated 2-dimensional
transport code. Managing water rights on Marathon’s oil shale property. Supervised a
visiting doctoral student from the Norwegian University of Science and Technology,
Institute for Petroleum Technology and Applied Geophysics, Stavanger, Norway during a
6-month program at Marathon.

U.S. Geological Survey - Hydrologist                                     1992 - 1998
Collaborated with a team of scientists studying the Toxic Substances Hydrology
Program crude-oil spill site near Bemidji, MN. Bemidji projects included the physics of
multiphase flow, organic chemistry of dissolved components, biodegradation, and
unsaturated zone processes. Masters thesis focused on the effects of aquifer
heterogeneity on multiphase flow at the Bemidji site. Doctoral thesis on nonaqueous
phase liquid dissolution provided a link between projects focusing on the physics of
multiphase flow, and the chemistry and biodegradation of the dissolved components.
Work at the USGS included computer simulation, analysis of laboratory data, and annual
summer field work at the Bemidji site.
