Paper: Continuous Gas Lift

In straight or continuous gas lift, the flow is continuous, that is, not interrupted by intermitting nor aided by any artificial pumping method for obtaining submergence. This type of gas lift resembles a flowing well more than does any other type of artificial method in producing a well. Gas is injected at the top of the well through the tubing or casing, as the case may be, and the flow of the oil and gas takes place through the other pipe rather than the pipe through which the gas is admitted.
