The Rock Physics Handbook, 2nd Edition
Mavko, Mukerji, and Dvorkin
In the decade since publication of the Rock Physics
Handbook, research and use of rock physics has thrived. We hope that the First Edition has played a useful
role in this era by making the scattered and eclectic mass of rock physics
knowledge more accessible to experts and non-experts, alike.
While preparing this
Second Edition, our objective was still to summarize in a convenient form many
of the commonly needed theoretical and empirical relations of rock
physics. Our approach was to present results, with a few of the key
assumptions and limitations, and almost never any derivations. Our intention
was to create a quick reference and not a textbook. Hence, we chose to
encapsulate a broad range of topics rather than give in-depth coverage of a
few. Even so, there are many topics that we have not addressed. While we have
summarized the assumptions and limitations of each result, we hope that the
brevity of our discussions does not give the impression that application of any
rock physics result to real rocks is free of pitfalls. We assume that the
reader will be generally aware of the various topics, and, if not, we provide a
few references to the more complete descriptions in books and journals.
The handbook contains
101 sections on basic mathematical tools, elasticity theory, wave propagation,
effective media, elasticity and poroelasticity, granular media, and pore-fluid
flow and diffusion, plus overviews of dispersion mechanisms, fluid
substitution, and VP–VS relations. The book also
presents empirical results derived from reservoir rocks, sediments, and
granular media, as well as tables of mineral data and an atlas of reservoir
rock properties. The emphasis still focuses on elastic and seismic topics,
though the discussion of electrical and cross seismic-electrical relations has
grown. This associated website (http://srb.stanford.edu/books/RPHII/RPHtools)
offers MATLAB codes for many of the models and results described in the Second
Edition.
In this Second Edition, Part 2 has been expanded to
include new discussions on elastic anisotropy including the Kelvin notation and
eigenvalues for stiffnesses, effective stress behavior of rocks, and
stress-induced elasticity anisotropy.
Part 3 includes new material on anisotropic NMO and reflectivity, AVO
relations, plus a new section on elastic impedance (including anisotropic
forms), and updates on wave propagation in stratified media, and borehole
waves. Part 4 includes updates of
inclusion-based effective media models, thinly-layered media, and fractured
rocks. Part 5 contains extensive new
sections on granular media, including packing, particle size, sorting,
sand-clay mixture models, and elastic effective medium models for granular
materials. Part 6 expands the
discussion of fluid effects on elastic properties, including fluid substitution
in laminated media, and models for fluid-related velocity dispersion in
heterogeneous poroelastic media. Part 7
contains new sections on empirical velocity-porosity-mineralogy relations,
Vp-Vs relations, pore-pressure relations, static and dynamic moduli, and
velocity-strength relations. Part 8 has
new discussions on capillary effects, irreducible water saturation,
permeability, and flow in fractures.
Part 9 includes new relations between electrical and seismic properties.
Part 10 has new tables of physical constants and properties for common gases,
ice, and methane hydrate.
