Abstract

Liquid loading in gas wells is a multiphase flow phenomenon where the liquid content of the well creates back pressure (usually dominated by gravitational pressure changes) which restricts, and in some cases even stops, the flow of gas from the reservoir. The industry recognizes the importance of liquid loading and tries to alleviate the problem using various measures, yet the fundamental understanding of the associated multiphase phenomena remains weak. This paper discusses the complexity of the multiphase flow phenomena associated with liquid loading in gas wells. An extensive review of the current modeling solutions available to predict the arrival of liquid loading, diagnose its impact on production and screen remedial options is presented. The paper also critically reviews recent attempts to model the dynamic interactions between reservoir and wellbore. The review highlights the limitations of the current models, stressing the need for a fully transient multiphase flow approach.
