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
