Enter value and click on calculate. Result will be displayed.

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

Enter your values:
Oil Density: Lb / ft3
Gas Density: Lb / ft3
Drainage Radius of Well: Ft
Well Bore Radius: Ft
Effective Oil Permeability: mD
Oil Viscosity: cp
Oil Formation Volume Factor:
Oil Column Thickness: Ft
Perforated Interval: Ft
Critical Oil Flow Rate: STB / day

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.
