Seismic Rock Properties and Rock Physics
The essence of seismic-related rock physics consists of finding relationships between seismic rock properties and their petrographic and petrophysical parameters, including their mineralogy, texture, diagenesis, reservoir properties, and effective stress. These problems are discussed in Chapter 3. The chapter also addresses certain controversial issues, such as parameterization and appropriate model selection. The outcomes of this discussion are several rock-physics templates that feature the key petrophysical groups of siliciclastics in velocity-versus-porosity space and acoustic-impedance-versus-shear-impedance (AI-SI) space. Those templates naturally incorporate the effect of rock compaction and diagenesis and therefore are essential in modern seismic inversion interpretation.

Seismic Petrophysics in Quantitative Interpretation is written for oil and gas industry professionals and academicians who are concerned with the use of seismic data in petroleum exploration and production. In addition, it should prove useful toward thoughtful applications of those data by geotechnical engineers. Seismic interpretation can be made simple and robust by integrating rock-physics principles with the seismic and petrophysical attributes that bear on the properties of conventional reservoirs (thickness, net/gross, lithology, porosity, permeability, and satu-ration) and of unconventional reservoirs (thickness, lithology, organic richness, and thermal maturity). Practical solutions can be used to address existing interpretation problems in rock-physics-based AVO analysis and prestack seismic inversion in order to streamline the workflows in subsurface characterization.
