Horizontal maximum stress (Bredehoeft)
Input(s)
\(S_{\text {hmin }}\): Minimum Horizontal Stress (psi) \(P_{b}\): Breakdown Pressure at initial Hydrofrac (psi)
\(P_{p}\): Pore Pressure (psi)
Output(s)
\(S_{\text {hmax }}\): Maximum Horizontal Stress (psi)
Formula(s)
\[
\mathrm{S}_{\mathrm{h} \max }=3 * \mathrm{~S}_{\mathrm{h} \min }-\mathrm{P}_{\mathrm{b}}-\mathrm{P}_{\mathrm{p}}
\]
