Many factors are involved when selecting the most cost effective artificial lift system. This paper will discuss the advantages of The DynaPump Intelligent Long Stroke Hydraulic Pumping System compared to other artificial lift systems. This system has characteristics that allow for operation at much slower strokes per minute greatly reducing tubing and sucker rod wear while retaining the ability to produce at greater volumes from deeper depths than conventional beam pumping units. This system also has features that provide superior efficiency and flexibility at any rate and depth compared to other artificial lift methods. This study compares electrical efficiency, well intervention costs, production optimization, adaptability to changing well conditions, ability to operate in harsh well conditions, and overall environmental impact between various artificial lift methods. Included are actual operating parameters and runtime comparisons. The conclusions will aid in the selection of present and future artificial lift system requirements.
