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

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}}

where

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