Course Description:
Instructor Bio:
Dr. Wahid Rahman is currently working as the Director of Laboratories and Geoscience at Impac Exploration Services, Houston Texas. Dr. Rahman has previously worked as Sr Staff Scientist/Program Coordinator at Texas Commission on Environmental Quality (TCEQ), Austin, Texas; as Director at Geoscience at Geoscience and Petroleum Research Inc, Houston, Texas; as Chief Geochemist at Paladin Geological Services, Edmond, OK; as Geological Adviser at Ossidiana Energy, Denver, CO; Staff Geochemist-Petroleum Systems Analyst at Pioneer Natural Resources, Irving, Texas; and as Sr Geochemist-Petroleum Systems Analyst at Devon Energy, Oklahoma City, OK. Dr Rahman has 20+ years of industry, academic, and research experience in the field of geochemistry, basin modeling, petroleum systems analysis, environmental geochemistry, and geology. Wahid worked on most of the North American onshore unconventional and conventional petroleum plays/basins including Gulf of Mexico (GOM) and many international basins. Dr Rahman’s research interest include organic geochemistry, Petroleum systems analysis/basin modeling, environmental geochemistry, isotope geochemistry, surface geochemistry, conventional and unconventional resource play evaluation, HC migration pathway analysis, thermal maturity of organic matter (OM) and hydrocarbons (oil and gas), relationship between OM maturity to Gas-to-Oil ratio (GOR), pressure gradient, kerogen/OM density, formation water geochemistry to figure out reservoir continuity, water resistivity (Rw), water saturation (Sw), well completion geochemistry, stable isotope geochemistry, production allocation and reservoir geochemistry. Wahid has over 50 conference presentations, papers, and peer reviewed journals (with more than 750 citations) in the field of geochemistry, environmental geochemistry, and geology. He received his Ph.D. in Organic Geochemistry from Southern Illinois University, Carbondale, IL; M.S. in Geology from Auburn University, Auburn, AL; M.S. and B.S. in Geology from University of Dhaka, Dhaka, Bangladesh.
- The Geochemistry course will provide introduction and evolution of conventional and unconventional petroleum systems. The intent is to cover most of the geochemical methods: total organic carbon (TOC), organic facies (kerogen/macerals types), vitrinite reflectance/thermal maturity (Ro) and its equivalent (VRoE) from bitumen, pyrolysis data (hydrogen index, Tmax,) and produced oil and gas.
- Geochemistry to understand Level of Organic Maturation (LOM), prediction of hydrocarbon phase, API gravity, gas-to-oil ratio (GOR), condensate-to-gas ratio (CGR), production allocation and identifying Drainage volume (DRV)
- Geochemist data to analyze and understand petroleum systems from molecular scale to basin scale through basin modeling.
- Course will also cover oil to oil and oil to source rock correlations through Source Rock (e.g. TOC, SRA, Rock-Eval) and produced hydrocarbon (oil and gas) though geochemistry data (GC, GCMS, GC-IRMS).
- There will be examples from different US onshore unconventional resource plays (e.g., Anadarko Basin) and conventional plays from published data.
- Course attendees will be able to learn the fundamentals and application of geochemistry to exploration, development and production of oil and gas for both conventional and unconventional plays.
