Reservoir flow for gas flow in a formation
Input(s)
\(n\): The Performance Exponent (dimensionless)
\(\bar{p}\): The Mean Formation Pressure in the Drainage System of Well (psi)
\(P_{w f}\): Bottomhole Flowing Pressure (psi)
C: Performance Coefficient, a Function of Mean Pressure Level (bbl/d psi)
Output(s)
\(W\): Flow Rate \((\mathrm{bbl} / \mathrm{d})\)
Formula(s)
\[
\mathrm{W}=\mathrm{C}\left(\overline{\mathrm{p}}^{2}-\mathrm{p}_{\mathrm{wf}}^{2}\right)^{\mathrm{n}}
\]
