... The typical diagram of plunger lift system assembly is shown in Fig. 4 . Understanding the concept of critical velocity is essential for efficient well operations and preventing issues caused by liquid buildup. Critical velocity is the minimum speed with which gas needs to flow in a well...

... model. Aires et al. (2020) implemented and compared three control techniques for plunger lift: a fixed set of on-stage and off-stage times, fuzzy logic, and model predictive control (MPC). In addition, they extended their study to the case when a second control valve is connected to the casing...

... Abstract This paper presents a "full lifecycle" approach to well production that encompasses three interrelated forms of artificial lift ‒ gas lift, plunger-assisted gas lift (PAGL), and plunger lift ‒ applied at distinct phases to collectively span the entire slope of the tight oil well...

... Abstract Liquid loading is common in high gas-liquid ratio (GLR) wells with low reservoir pressure. Plunger lift is an artificial lift method many operators use to remove liquid accumulation in their wells. It is widely used due to its flexibility and cheap operational cost. Accurate prediction...

... Abstract A mechanistic plunger lift tool was developed to estimate cycle mechanics, liquid unloading, and avoid well integrity issues. The study focuses on the plunger-assisted gas lift (PAGL) wells operated with the two-piece plunger under low tubing wellhead pressure conditions. The fall...

... Abstract Plunger lift is a form of artificial lift popular due to its low installation and operating costs. Historically plunger lift was reserved for low producing stripper gas wells due to limitations on liquid rate and gas volume requirements. More recently, the use of continuous run...

... Abstract Conventional plunger lifting is a transient process that consists of cyclic openings and closings of a gas well. Because of this complex behavior, using traditional physics-based models to simulate the coupled behavior of reservoir and wellbore performance is computationally rigorous...

... analysis, it was found that the fall velocity depends mainly on the type of plunger, air phase pressure, thickness of the liquid film on tubing wall, viscosity of the liquid, and density of the gas phase. Plunger lift is one of the most used deliquification method for gas wells. However, only a few...
