.... These scale restrictions can cause well performance issues which limit options for artificial lift. Through sampling and lab analysis, the primary types of scale found are calcium carbonate and iron sulfide. After several years of evaluation, plunger lift equipment was unable to be installed in 25-30...

... Abstract Gas-assisted plunger lift (GAPL) could be an effective and economically favorable artificial lift (AL) method to be considered during the AL life cycle for North American shale wells. The main advantage of GAPL is that it improves the well production by reducing liquid fallback...

... Abstract The interest in and demand for natural gas has dramatically shifted the focus for many operators in the past few years. Plunger lift, which for many years was viewed as a last resort, and somewhat of a nuisance, has gained an all time high in popularity, and effectiveness...

... Abstract Plunger Lift operations are oftentimes not optimized due to lack of knowledge of plunger location and changes in tubing pressures, casing pressures and bottomhole pressures. Monitoring the plunger location in the tubing helps the operator to optimize the production of liquid and gas...

... ABSTRACT New developments in controller design that simplify plunger lift operations and obtain maximum production are always needed. Many plunger lift wells are currently operated by electronic controllers which utilize either time and/or pressure to regulate production. Some monitor casing...

... Four categories of wells were studied to illustrate the optimization technique of Nodal analysis for the solution of production problems. Mechanical plunger (rabbit). Sucker-rod (pump-jack). Stimulation. Drill deeper. Gas is the predominant fluid in the Appalachian wells, oil...
