Multiple Short Course Programme
Rock Physics for Quantitative Seismic Reservoir Characterization
|Tapan Mukerji, Stanford University|
|5 CPD points|
This course covers fundamentals of Rock Physics ranging from basic laboratory and theoretical results to practical “recipes” that can be immediately applied in the field. We will present quantitative tools for understanding and predicting the effects of lithology, pore fluid types and saturation, saturation scales, stress, pore pressure and temperature, and fractures on seismic velocity. We will present case studies and strategies for quantitative seismic interpretation and, suggestions for more effectively employing seismic-to-rock properties transforms in reservoir characterization and monitoring, with emphasis on seismic interpretation for lithology and subsurface fluid detection.
- Introduction to Rock Physics, motivation, introductory examples
- Parameters that influence seismic velocities - Conceptual Overview
effects of fluids, stress, pore pressure, temperature, porosity, fractures
- Bounding methods for robust modeling of seismic velocities
- Effective media models for elastic properties of rocks
- Gassmann Fluid substitution – uses, abuses, and pitfalls
derivation, recipe and examples, useful approximations
- Partial saturation and the relation of velocities to reservoir processes
- The importance of saturation scales and their effect on seismic velocity
- Shaly sands and their seismic signatures
- Granular media models, unconsolidated sand model, cemented sand model
- Velocity dispersion and attenuation; Velocity Upscaling
- Rock Physics of AVO interpretation and Vp/Vs relations
- Quantitative seismic interpretation and rock physics templates.
- Example case studies using AVO and seismic impedance for quantitative reservoir characterization
The course is recommended for all geophysicists, reservoir geologists, seismic interpreters, and engineers concerned with reservoir characterization, reservoir delineation, hydrocarbon detection, reservoir development and recovery monitoring.
