Hagoort and Hoogstra gas flow in tight reservoirs

Input(s)

Г: Transmissibility between Compartments (dimensionless)

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

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

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

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

Output(s)

Q: Gas Flow (MSCF/d)

Formula(s)

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