The Petroleum Geoscientist - A Detective Predicts where oil and gas occurs by using well data and ‘remote sensing’Predicts where oil and gas occurs by using well data and ‘remote sensing’ Uses tools to gather data - gravity and magnetics rock distribution and properties geophysical imaging computer process & visualizationUses tools to gather data - gravity and magnetics rock distribution and properties geophysical imaging computer process & visualization Uses concepts to develop models: structural concepts, petrol systems, etcUses concepts to develop models: structural concepts, petrol systems, etc Makes economic analysis and recommends drillingMakes economic analysis and recommends drilling From Armentrout, 2000, AAPG.org

7. GEOSCIENCE SKILLS Companies differ, but All favor a mixture: science, computer, non-tech Geology & Geophy Fieldwork and mapping experience are important Top Technical Skills: –Petroleum Geol –Geophysics –Sedimentology –Mapping –Strat/Sequence Strat –Petroleum Systems –Regional Geology –Reservoir Geology Heath, 2002

8. What makes a successful Petroleum Geologist? Strong fundamentals in geologic principles are key to a successful career –Science first, business second Strong understanding of science –Hypothesis testing –Creativity and considering alternatives –Ability to reach conclusions and make recommendations Don’t need universities to be trade schools Students focus classes and research in grad school, but a broad geologic background is needed for the job Slide added by Rick Abegg

9. Additional Considerations Most companies require MS/PhD degree Internships are recommended –Prepare for any interview –Show interest (e.g. field trips, short courses, etc.) Geophysicists are in high demand What’s the future for careers in petroleum geology? –Strong demand for hydrocarbons in developing countries. –Large population to retire in the next 5-10 years Slide added by Rick Abegg
