... 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...

... plunger or its components will fall against flow with the well open to production. Plunger Lift Operation Cycle An additive modification to the Foss & Gaul relationship is derived in Appendix A to account for the fact the well is producing some gas into the tubing below the plunger...

... plunger lift. Given the consideration of low rates, economic feasability, well characteristics and mechanical integrity, plunger lift became the obvious choice. Plunger lift is an intermittent form of artificial lift which utilizes the natural energy of the reservoir to lift the liquids out...

... 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...

... Abstract Tracking the fall of the plunger down the tubing can be used to optimize the operation of plunger lifted wells. Acoustic fluid level instruments can be used on plunger lifted wells to acquire a series of plunger/fluid level soundings and/or to record the acoustic signal produced...

... into the wellbore throughout the plunger cycle. Plunger Lift Analysis One should recognize there is a distinct difference in operating a plunger in an oil well or a gas well. When used in the oil well, the purpose is to optimize liquid production. In a gas well, one desires to optimize the gas production...

... consistent foaming action for unloading efficiency. The capillary string is easily installed and can be transferred from one well to another. In many cases the soap injection from capillary tubing has out performed the more conventional plunger lift. The injection system is also very effective in treating...

... 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...

... ABSTRACT The increasing recognition of Plunger-Lift as a viable method for producing many wells, has brought a number of changes to the technology involved. The importance of proper plungerlift performance criteria (as reported in an earlier SPE paper) has been recognized and steps taken...
