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)
\[
P_{i n j}=P_{F}+\Delta P_{f}+\Delta P_{p}-\Delta P_{h}
\]
