Qoc = Critical Oil Flow Rate
o = Oil Density
g = Gas Density
re = Drainage Radius of Well rw = Well Bore Radius Ko = Effective Oil Permeability
Uo = Oil Viscosity Bo = Oil Formation Volume Factor
hp = Perforated Interval h = Oil Column Thickness
Mayer & Garder were the first to proposed this concept for determining the Critical oil flow rate for
a gas-oil isotropic reservoir with the perforated interval at the lower bottom of the oil zone.
