Poisson's ratio (seismic arrival time method)
Input(s)
\(V_{p}\): Velocity of Compressional Waves \((\mathrm{ft} / \mathrm{s})\)
\(V_{s}\): Shear Waves \((\mathrm{ft} / \mathrm{s})\)
Output(s)
v: Poisson's Ratio (dimensionless)
Formula(s)
\[
v=\frac{\left(V_{p}^{2}\right)-2 *\left(V_{s}^{2}\right)}{2 *\left(\left(V_{p}^{2}\right)-\left(V_{s}^{2}\right)\right)}
\]
