Every gas well ceases producing as reservoir pressure depletes. The usual liquid presence in
the reservoir can cause further problems by accumulating in the wellbore and reducing
production even more. There are a number of options in well completion to prevent liquid
loading even before it becomes a problem. Tubing size and perforation interval
optimization are the two most common methods. Although completion optimization will
prevent liquid accumulation in the wellbore for a certain time, eventually as the reservoir
pressure decreases more, the well will start loading. As liquid loading occurs it is crucial to
recognize the problem at early stages and select a suitable prevention method. There are
various methods to prevent liquid loading such as / gas lift, plunger lift, pumping and
velocity string installation. This study set out to construct a decision tree for a possible
expert system used to determine the best result for a particular gas well. The findings are
tested to confirm by field applications as attempts of the expert system.
