Initial effective horizontal stress
Input(s)
v: Poisson (unitless)
\(\rho\): Overburden Density \(\left(\mathrm{lb} / \mathrm{ft}^{3}\right)\)
\(\mathrm{H}\): Formation Depth (ft)
\(\alpha\): Biot Constant (unitless)
\(p_{p}\): Reservoir Pressure (psi)
Output(s)
\(\sigma_{h}\): Effective Horizontal Stress (psi)
Formula(s)
\[
\sigma_{\mathrm{h}}=\left(\frac{v}{1-v}\right) *\left(\left(\rho * \frac{\mathrm{H}}{144}\right)-\left(\alpha * \mathrm{p}_{\mathrm{p}}\right)\right)
\]
