An improved model for predicting liquid loading onset in inclined pipes with non-uniform liquid wall films
Original language description
Liquid loading is a phenomenon in which liquid accumulates in the wellbore of mature gas wells, causing a significant reduction in production and sometimes permanent well abandonment. This paper introduces a new model for predicting liquid loading onset, based on the reversal of a non-uniform liquid film. The momentum balance equation for annular flow is, in the proposed model, expressed as a function of liquid holdup instead of liquid thickness. The model employs auxiliary correlations to obtain liquid holdup and an interfacial friction factor, developed from literature data.
