The plunger lift is one of the main methods to release liquid loading in gas wells. Due to the
leakage in the process of moving for plunger, the efficiency of liquid unloading is decreased …

As deep natural gas resources develop, conventional plunger lift are often inadequate due
to their high startup pressure, significant leakage, and frequent lift failures. For gas wells with …

Due to the depleted exploitation of shale gas reservoirs, liquid loading in horizontal wells
during the later stages of exploitation is a common problem. Among these, the plunger lift …
