ABSTRACT:
This talk is an overview of the importance of applying imaging and image analysis methods to understanding and modeling rock properties. The measured properties included in this discussion are Resistivity, Permeability, Velocity, and Compressibility. At the heart of these models is the concept that the relevant length scales have to be included in the models to accurately predict and upscale their properties. Staged Effective Medium models are used to include these differing length scales. This allows the influence of pore structure on rock properties to be discerned including the influence of: • Oil saturation on resistivity • Dispersed clays on the formation factor F* • Vugs on the formation factor of carbonates • Permeability • Velocity • Compressibility Brief explanations of the underlying models are presented for discussion. Future work is also discussed. The saturation data fits conceptually with the porosity and salinity dependent models under water wet assumptions. A changing saturation was found to be equivalent to a porosity change for the geometric dispersion. The clay term was found to be saturation independent. The work represents a significant step forward towards an integrated approach to understanding the dielectric and conductivity response of shaly sands.
BIOGRAPHY:
Dr. Michael T. Myers (Associate Professor, Ali Daneshy Endowed College Professor, University of Houston)
Dr. Myers has twenty five years research experience in rock and fluid properties at Shell International Exploration and Production. He served as an Adjunct Faculty at UH before joining the department full time. His research areas of interest include static and dynamic properties of porous media. He has a Ph.D. in Physics in Nonlinear Optics, from University of Michigan, M.S. Physics, from University of Michigan and B.S. Physics from Michigan Technological University.
Dr. Lori Hathon (Assistant Professor, University of Houston)
Dr. Hathon was senior research geologist for Shell International E&P, Inc. before she joined the UH Cullen College faculty. For more than two decades, her work has focused on routine and special core analysis, clastic petrology, reservoir quality analysis and predictive modeling, applications of image analysis to rock physics, organic petrography and thermal maturity analysis. Her experience has also included well-drilling operations and post-well appraisals. She has Ph.D. from University of Missouri.
