SHORT COURSES

Geochemistry for Evaluating and Developing Conventional and Unconventional Plays

Dr. Wahid Rahman

AAPG Midcontinent 2021

Sunday, October 3^rd ~ Full Day Course

Course Description: Geochemistry is the most useful tool for evaluating and developing conventional and unconventional plays (petroleum systems analysis to production allocation)

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 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 in both conventional and unconventional plays.

Dr. Wahid Rahman is currently working as a Petroleum Geochemist/Director at Geoscience and Petroleum Research Inc, Houston, Texas, USA. Dr. Rahman has previously worked as Chief Geochemist at Paladin Geological Services, Edmond, OK, Geological Adviser at Ossidiana Energy, Denver, CO, Staff Geochemist at Pioneer Natural Resources, Irving, Texas and as Sr Geochemist at Devon Energy, Oklahoma City, OK. Dr Rahman has 19+ years of industry, academic, and research experience in the field of geochemistry, basin modeling, environmental geochemistry and geology; worked on the most of the North American onshore unconventional and conventional petroleum plays/basins. Dr Rahman’s research interest include organic geochemistry, 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 versus Gas Oil Ratio (GOR), pressure gradient, kerogen/OM density, formation water geochemistry to figure out reservoir continuity, water resistivity (Rw), water saturation (Sw), inorganic geochemistry, well completion geochemistry, stable isotope geochemistry, production allocation and reservoir geochemistry. Wahid has over 35 conference presentations, papers, and peer- reviewed journals (with more than 600 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.
