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