Injection pressure for hydraulic fracturing

Input(s)

$P_{F}$: Downhole Fracturing Operation Pressure (psi)

$\Delta P_{f}$: Pressure Loss Sourced by Friction (psi)

$\Delta P_{p}$: Pressure Loss sourced by Perforations (psi)

$\Delta P_{h}$: Hydrostatic Pressure Change (psi)

Output(s)

$P_{\text {inj: }}$ Injection Pressure (psi)

Formula(s)

$$ P_{i n j}=P_{F}+\Delta P_{f}+\Delta P_{p}-\Delta P_{h} $$
