Stress perturbation (Segall and Fitzgerald)
Input(s)
\(v\): Poisson (dimensionless)
\(\mathrm{H}\): Height of Reservoir \((\mathrm{ft})\)
R: Half the Lateral Extent (ft)
\(\alpha\): Constant of Stress Propagation (dimensionless)
Output(s)
M: Stress Perturbation (dimensionless)
Formula(s)
\[
\mathrm{M}=\alpha *\left(\frac{(1-2 * \mathrm{v}) * \pi * \mathrm{H}}{(1-\mathrm{v}) * 4 * 2 * \mathrm{R}}\right)
\]
