Dimensionless vertical well critical rate correlations - Hoyland, Papatzacos, and Skjaeveland

Input(s)

$\mathrm{h}$: Oil Column Thickness (ft)

$k_{h}$: Effective Oil Permeability $(\mathrm{mD})$

$\rho_{w}$: Water Density $(\mathrm{g} / \mathrm{cc})$

$\mu_{o}$: Oil Viscosity $(\mathrm{cP})$

$\rho_{o}$: Oil Density $(\mathrm{g} / \mathrm{cc})$

$B_{o}$: Oil Formation Volume Factor (RB/STB)

$q_{o}$: Critical Oil Rate (STB/day)

Output(s)

$\mathrm{Q}_{\mathrm{oD}}$: Dimensionless Critical Rate (dimensionless)

Formula(s)

$$ Q o D=651.4 * \mu_{o} * B_{o} * \frac{q_{o}}{h^{2} *\left(\rho_{w}-\rho_{o}\right) * k_{h}} $$
