`Q_[o c]=0.246×10^-4([p_o-p_g]/[I n(r_e/r_w)])(K_o/[U_o×B_o])(h^2-h_p^2) `
Qoc = Critical Oil Flow Rate
po = Oil Density
pg = 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
