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)

$$ \mathrm{S}_{\mathrm{h} \max }=3 * \mathrm{~S}_{\mathrm{h} \min }-\mathrm{P}_{\mathrm{b}}-\mathrm{P}_{\mathrm{p}} $$
