Abstract

This chapter deals with the recognition and operation of gas wells experiencing liquid loading. It presents materials on methods and tools to enable the diagnosis of liquid loading problems and indicate how to operate more efficiently by reducing the detrimental effects of liquid loading on gas production. This study serves as a primer to introduce the majority of the possible and most frequently used methods that can help produce gas wells when liquids start becoming a problem. Be aware that liquid loading can be a problem in both high- and low-rate wells, depending on the tubular sizes, the surface pressure, and the amount of liquids being produced with the gas. This chapter discusses how to recognize liquid loading when it occurs, how to model gas well liquid loading, how to design well to minimize liquid loading effects, and what tools are available to assist in designing and analysis of gas wells for liquid loading problems. It also describes the best methods of minimizing the effects of liquids in lower velocity gas wells and the advantages and disadvantages of the best methods.
