I am a petroleum geologist whose primary interests lie in clastic sedimentology and stratigraphy. For much of my career, I have served as a consultant, performing a variety of reservoir characterization and exploration projects that have required solution of complex stratigraphic problems and quantification of geological information for use in reservoir simulators. I have also explored for oil and gas with onshore U.S. independents, and early in my career with majors, generating prospects in the Gulf Coast, Midcontinent, and Rocky Mountain regions.
