Brief

Liquid loading is a phemonenon when the gas phase does't provide sufficient transport energy to lift the liquids out of the well.

Math & Physics

The minimum gas velocity to remove the liquid equation:

 v_g = 1.593 \sigma^{1/4} \frac{({\rho_L-\rho_g})^{1/4}}{\rho_g^{1/2}}

The minimum gas rate to remove the liquid equation:

 q_g = 3.06 \frac{P v_g A}{T z}

Nomenclature

 v_g = gas velocity, ft/sec
 \sigma = surface tension, dyne/cm
 \rho_L = liquid density, lbm/ft3
 \rho_g = gas density, lbm/ft3
