Geology for Non-Geologists (4 Day)
No events scheduled
This popular four-day course will provide non-geologists with a practical understanding of the principles used by petroleum geologists in the search for oil and gas. The sessions will include both the scientific background and the practical applications of geology. The tools, techniques, and vocabulary of the petroleum geologist will be emphasized throughout the course.
Duration and Training Method
Four classroom days providing 3.2 CEU (Continuing Education Credits) or 32 PDH (Professional Development Hours)
Participants will learn to:
• Understand how the nature of geology itself affects the way geologists approach problem solving.
• Describe the paradigm of plate tectonics and how modern exploration uses the concepts of the plate tectonic model in the search for oil and gas.
• Communicate more effectively in geoscience meetings through an understanding of the terms, tools, and techniques used in the exploration and development of hydrocarbons.
• Tell the difference between rock types and know why some are, or are not, suitable reservoirs for oil and gas
• Define the concept of the petroleum system and how it aids in the interpretation and evaluation of hydrocarbon generation, maturation, migration, and accumulation.
• Understand the information illustrated through the construction and interpretation of cross sections and maps.
• Describe the importance and use of analogs in interpreting subsurface data.
• Distinguish the difference between stratigraphic and structural traps for oil and gas and how to recognize them from cross sections and maps.
• Know how to recognize different depositional environments using facies maps, isopachs, and fence diagrams.
• Describe the importance of environments of deposition in predicting the distribution, location, and geometry of reservoir rocks.
• Describe the difference between porosity and permeability and discuss the importance of each in conventional and unconventional reservoirs.
• Describe the characteristics of shales and the geologic parameters that control "sweet spots" in shale plays
• Understand the basics of well-log analysis and formation evaluation, including basic tool types, their measurements, and interpretation of lithology, porosity, and water saturation
• Calculate oil-in-place (OIP) reserves using log-derived data.
• Appreciate the importance of sample examination and the recognition and interpretation of oil shows at the wellsite.
• Understand the basic principles of seismic prospecting and know the difference between 2D, 3D, and 4D seismic.

Paul H. Pausé is an independent petroleum geologist in Midland, Texas, centrally located in the prolific and currently booming Permian Basin of west Texas and southeast New Mexico.He earned a bachelor's degree in geology at the University of California at Berkeley, and a master's degree in geology at UCLA.
Paul began his career as a petroleum geologist with AtlanticRichfield Company, and moved to Midland, Texas, with ARCO in 1977. After leaving ARCO, he worked for JM Huber, Davis Oil, and HCW Exploration. Paul now consults on exploration and development projects, generates and sells his own drilling prospects, and teaches courses in petroleum geology at the Petroleum Professional Development Center in Midland, and worldwide through public and in-house offerings.
Paul is an active member of several professional societies including the American Association of Petroleum Geologists (AAPG), Geological Society of America, the Geological Society of London, the Petroleum Exploration Society of Great Britain, the Society of Independent Professional Earth Scientists (SIPES), and the West Texas Geological Society.
Paul has received the Dedicated Service award from the WTGS and the Permian Basin Section SEPM and has been awarded Honorary Life Membership in both organizations, their highest recognition. He is a recipient of the A.I. Levorsen Award for Best Paper Presentation at the Southwest Section meeting of the AAPG.
