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:
The minimum gas rate to remove the liquid equation:
Nomenclature
= flow area, ft^2
= flowing pressure, psia
= gas rate, MMscf/d
= gas density, lbm/ft3
= liquid density, lbm/ft3
= surface tension, dyne/cm
= flowing temperature, °R
= gas velocity, ft/sec
= gas compressibility factor at flowing P & T
