McKee, F E

A method of optimizing the production of well fluids from a well by gas lift is described comprising, determining the time delay for various constant injection gas flow rates to produce a constant liquid flow rate, determining the relationship between the injection gas flow rate to the well and the amount of liquid produced from the well between a minimum and a maximum gas flow rate, selecting the amount of liquids which are desired to be produced and determine the required injection gas flow rate required to produce the desired amount of liquid, measuring the amount of fluids produced from the well and the injection gas flow rate, calculating the difference between the present injection gas flow rate and the required injection gas flow rate to produce the selected amount of liquids, and adjusting the gas flow rate considering the time delays to reach the required injection gas flow rate without injecting more gas than is needed.
