Hagoort and Hoogstra gas flow in tight reservoirs

Input(s)

Г: Transmissibility between Compartments (dimensionless)

P1P_{1}: Pressure of Compartment 1(psi)1(\mathrm{psi})

P2P_{2}: Pressure of Compartment 2(psi)2(\mathrm{psi})

μgavg \mu_{\text {gavg }}: Average Viscosity (cP)(\mathrm{cP})

Bgavg B_{\text {gavg }}: Average Gas Formation Factor (MSCF/STB)

Output(s)

Q: Gas Flow (MSCF/d)

Formula(s)

Q=Γ(P12P22)2P1μgavg Bgavg Q=\frac{\Gamma *\left(P_{1}^{2}-P_{2}^{2}\right)}{2 * P_{1} * \mu_{\text {gavg }} * B_{\text {gavg }}}
