Errata for the 3rd edition (2020) of the Rock Physics Handbook

  • Page 359: soft-sand model.

The variable adhesion version of \(\mu_{\mathrm{HM}}\) should have \(\phi\) replaced with \(\phi_0\) to be consistent with the “critical porosity” discussion prior.

Equation 5.5.138 should read:

\[\mu_{\mathrm{HM}}=\frac{2+3 f-v(1+3 f)}{5(2-v)}\left[\frac{3 C^2(1-\phi_0)^2 \mu}{2 \pi^2(1-v)^2} P\right]^{1 / 3}\]

  • Page 369:

A typo in equation 6.1.13, should be \(\rho_{fl}\), not \(\rho_{fi}\).

Equation 6.1.15 should read:

\[\frac{1}{V_{\mathrm{P}}^2}=\frac{-\left(H q+M \rho-2 C \rho_{\mathrm{fl}}\right) \pm \sqrt{\left(H q+M \rho-2 C \rho_{\mathrm{fl}}\right)^2-4\left(C^2-M H\right)\left(\rho^2_{\mathrm{fl}}-\rho q\right)}}{2\left(C^2-M H\right)}\]

Equation 6.1.16 should read:

\[\frac{1}{V_{\mathrm{S}}^2}=\frac{q \rho-\rho^2_{\mathrm{fl}}}{q \mu_{\mathrm{fr}}}\]

Fluid density should be squared.

  • Page 388

Equation 6.6.6 should read:

\[s_{i j k l}^{\mathrm{sat}}=s_{i j k l}^{\mathrm{dry}}-\frac{\left(s_{i j a a}^{\mathrm{dry}}-s_{i j a a}^0\right)\left(s_{b b k l}^{\mathrm{dry}}-s_{b b k l}^0\right)}{\left(s_{c c d d}^{\mathrm{dry}}-s_{c c d d}^0\right)+\phi\left(\beta_{\mathrm{fl}}-\beta_0\right)}\]

i.e. there should be a minus sign \(s_{i j k l}^{\mathrm{sat}}=s_{i j k l}^{\mathrm{dry}}-(...)\)

Eq. 6.6.7 is correct:\(s_{i j k l}^{\mathrm{sat}}=s_{i j k l}^{\mathrm{dry}} + (...)\)

In the text below equation 6.6.6, there is a typo: \(\beta_{fl}\) is the fluid compressibility. And comma is missing before \(\beta_{fl}\)

  • Page 458

Equation 6.22.8 should read:

\[\log _{10}\left(R_{\mathrm{G}}\right)=\log _{10}\left(0.712 P|T-76.71|^{1.5}+3676 P^{0.64} )-4-7.786 S(T+17.78)^{-0.306}\right.\]

Right closing parentheses missing after \(P^{0.64}\).

  • Page 465: The coefficient should be instead of 0.133. The same applies to the numerical example (page 468).

\[\epsilon = 0.113\]

Errata for the 1st Edition (1998) of the Rock Physics Handbook

  • Page 219: Physical Properties of Gases and Fluids

The equation for Bo should have …+T+17.8 within the brackets and not …+T+1.78. This correction also applies to the worked example on page 219.

  • Pages 244-249: Empirical Relations

The section headings for “Greenberg-Castagna” (page 246), “Williams” (page 248), and “Xu and White” (page 249) should be two levels higher. They are not meant to be sub-sections within “Krief’s Relation” but are separate sections by themselves.

  • Page 71: Viscoelasticity and Q

The third displayed equation for 1/Q from the bottom of the page should be an approximate equality and not an exact equality.

  • Page 155: Cemented Sand Model

Equation for C_tau, shoud have +10^(-4) as in Geophysics paper Dvorkin & Nur 1996, not -10^(-4).

  • Reference to J.G.

Berryman, 1995 “A Handbook of Physical Constants”, AGU - the citation should read “Rock Physics & Phase Relations: A Handbook of Physical Constants”.

  • Section 7.1, top of page 222

It says: “In the suspension domain, POR > POR_crit, the effective bulk and shear moduli can be estimated quite accurately using by the Reuss (iso-stress) average”. Either the word “using” or the word “by” in this sentence needs to be removed.

  • Section 7.8, page 245

It says that Beta = POR/POR_crit for 0<=POR<=POR_crit and that Beta = 1 for POR < POR_crit. The last inequality is incorrect. It should be “… for POR > POR_crit”.

  • Equation S=(3/2)(1-Phi)/d in the middle of page 261 should be S=6(1-Phi)/d

  • Page 157

Typo in the denominator of the Geff calculation. (3/6)*(9*2+8*6)/(2+2*3) = 2.625. Then Geff = 3.97

  • Page 217

Equation at the very bottom: 1/b = 0.306 - 7.6/M is right. The one in RPH and Batzle-Wang equation (16) giving b = 0.306 - 7.6/M is a typo.

  • NOT A TYPO!

Page 215, third line from the bottom: 1820S^2 should NOT be 820S^2 RPH is correct (1820 S^2). 820 S^2 in Batzle & Wang Geophysics paper is typo.

  • Page 70

Eqn.2 last term should be 2*mu*epsilon_ij.

  • Page 144

The formula for f should be f = rho * (Vp^2 – 2*Vs^2)
