... 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...

... through the tubing, while other features cause the plunger to have a slow fall velocity. By accurately measuring the plunger fall velocity, the proper shut-in time for the plunger lift installation can be determined. The plunger trace measurements will ensure that the plunger has reached the fluid...

... the original liquid slug during each cycle. The additional liquid increases the bottomhole flowing pressure and, hence, decreases production. In general, plunger lift installations are used to produce high gas-liquid ratio (GLR) oil wells or for unloading liquids in gas wells. Major advantages over other...
