* All wells are operating from a conventional beam pumping unit.
However, over the long-term application, the long-stroke with low-speed produces the best financial and mechanical advantages for the beam pumping unit.
* The change of pumping speed has shown an important and strong effect on loading and stress of the beam pumping unit. This leads to various inefficiencies and creates a financial loss in the long run.
It is a fully automated self-optimizing beam pumping unit, which enables continuous, maximum production, least production deferment and less operator's intervention, hence making it safer and cost effective.
Currently the most widely used beam pumping unit system is shown in Fig.2 [5,6,7,8].
