Paper: Analysis of Gas Lift Installations

A common error in utilizing gas lift as a means of artificial lift is the failure to properly analyze the completed installation. This, of course, has resulted in low efficiencies, and poor operations. Quite often the operator finds that excessive gas is being used or that production is low on a particular lease. However, it may be that a complete analysis of required injection gas has never been made. A common tendency for the field operator is to increase injection gas rates in an attempt to move more oil from the well. This may actually result in decreased production.
