Many low-volume gas well produce at suboptimum rates because of liquid loading caused by an accumulation of liquids in the well- bore that creates additional backpressure on the reservoir and reduces production. Plunger lift is an artificial lift method which can use reservoir energy to remove these accumulated liquids from the wellbore and improve production. Lacking a thorough understanding of plunger lift systems leads to disappointing results in many applications.
