Methods to eliminate annulus heading in continuous flow gas lift wells should be based on the principle that the choking effect exercised at the surface injection orifice, relative to that of the down-hole orifice, should be decreased. By so doing, annulus pressure is prevented from reaching a very low value, and continuous injection of gas through the down-hole orifice is maintained. The first segment of this 2-part series addressed the subject of equilibrium conditions in continuous-flow gas lift wells and introduced the concept of the equilibrium curve. This concluding installment discusses (1) methods to eliminate or control cyclical heading, and (2) a simulated gas lift computer model that analyzes this behavior.
