... Abstract Plunger lifted, and free-flowing gas wells experience a wide range of issues and operational inefficiencies such as liquid-loading, downhole and surface restrictions, stuck or leaking motor control valves, and metering issues. These issues can lead to extended downtime, equipment...

... Abstract Liquid loading is an important determinant for the performance of tight, unconventional gas wells. Although plunger lift is one of the best solutions when applicable, marginal economics of unconventional gas production does not tolerate un-optimized plunger lift performance...

... how changing a feature like plunger weight can impact fall velocity. The model's predicted fall velocity for different types of plungers will be compared with measured fall velocities. A large scale plunger lift well simulator was used to determine plunger fall behavior in clear PVC tubing through...

... into the CT To meet the liquid and plunger lifting capacity requirements, the pressure at the bottom of the U-shaped tank must satisfy the following equation: (14) p W F i = ⌊ ( ρ G   g h C T +   800 ) − Δ p i ⌋ − ρ m i x   g h m i x...

... ABSTRACT Smart plungers 1 can be used to enhance diagnostics and performance evaluation of liquid-loaded gas wells. The objective of this work is to develop a framework in which surface measurements and smart plunger data from the Pinedale field are analyzed using a mechanistic plunger lift...

... Abstract Plunger lift system installations throughout the United States are experiencing an alarming boom as liquid loading becomes an ever-increasing impediment to hydrocarbon recovery in depleting wells. Newly installed plunger lift installations within a field normally required individual...

... Abstract Accurate prediction of the average plunger rise velocity is important to optimally unload liquid from a plunger lifted well. A modified Foss and Gaul model presented in this paper predicts the minimum build casing pressure criteria to open the motor controlled valve for a selected...

... Abstract Plunger lift technology has been applied systematically and successfully to unload liquids from marginal tight gas and coalbed methane wells in San Juan North Basin. This article presents the recommended practices, case studies, and results of excellent plunger lift application...

.... The valve is closed automatically or manually and the plunger falls. As it is desirable that the plunger falls fast, many plungers have mechanisms which open a passage through or around the plunger, enabling faster falling speeds. Plunger lift is a common artificial lift method of producing liquids from...

... drillstem/well testing mccoy podio petroleum engineer plunger lift procedure operation Introduction The most common application of an acoustic liquid level instrument is to measure the distance to the liquid level in the casing annulus of a well. A single test is performed on a well...

... Plunger lift is a low cost method for lifting liquids (water, condensate and/or oil) from gas and oil wells. This system reduces the cost of operating a well compared to other artificial lift methods, because the formation pressure supplies the energy used to lift the liquids. During plunger lift...

...Plunger Lift Operation When it has been determined that a well has a potential application for plunger lift, one must carefully gather the well information and design the plunger lift installation. There are several static and dynamic methods for estimating plunger performance as stated...

... capillary tubing has out performed the more conventional plunger lift. The injection system is also very effective in treating downhole corrosion, paraffin and scale, buildup and in dissolving salt buildup. This capillary injection system could provide a new approach to solving many oil and gas well...

... ABSTRACT Operational conditions for a plunger lift installation are analyzed based on qualitative observations on a reduced experimental facility and simulations with a simple hydrodynamic model. Despite many simplifications, model predictions for daily production and pressure behavior...

... Abstract A review of 289 completions in Ochiltree County, Texas, shows 137 classified gas completions currently produce with the aid of artificial lift. Two methods of artificial lift, beam pumping units and plunger lift, were identified in the review. The study revealed that 130 gas wells...

...NEW SOFTWARE DESIGN As microprocessors have helped most other industries, so have they made a difference in plunger-lift. Both hardware and software have been introduced to make the plunger-lift system simpler and easier than ever imagined. In monitoring pressures, it was not possible...
