An integrated wellbore/reservoir model was used to investigate liquid loading in a gas well. The well produces from a storage reservoir; and it experiences water coning from an aquifer. The integrated model showed how the water cone caused the gas-flow rate from each gas layer to decrease and the liquid holdup in the wellbore to increase. Depending on reservoir conditions; the well may enter into a mode of unsteady production; during which the gas-flow rate cycles over a period of several days. The simulation revealed the reason for this unsteady flow;
