This paper discusses the principle of plunger lift and its possible applications.

Typical applications are:

  1. Removal of Liquids from Gas Wells

  2. Hi-Ratio Oil Well Production

  3. Paraffin and Hydrate Control

  4. Increased Efficiency of Intermittent Gas Lift Wells

Some advantages of this system are low initial cost, very little maintenance and that there is no external source of energy required in most cases. Limitations such as mechanical conditions, gas and liquid volumes and depths are also discussed. There will be a brief section concerning the various types of equipment available.
