Sucker rod pump, rod pump, reciprocating pump or pump jack is different names of an oldest and most widely used artificial lift method for oil wells. There is a high percentage of oil wells in North America and other areas in the world that are vertical and produce less than 10 barrels of oil per day.

An Improved Model for Sucker Rod Pumping
Society of Petroleum Engineers Journal, 1983Abstract An improved model for predicting the behavior of sucker rod pumping installations is presented. This model incorporates the dynamics of the liquid columns as well as the sucker rod string through a system of partial differential equations.

System Analysis for Sucker-Rod Pumping
SPE Production Engineering, 1989Summary Pumping free gas in an oil well can significantly decrease the efficiency of a sucker-rod-pumping installation. Pump placement depth and use of a downhole gas/liquid separator (gas anchor) were found to be significant variables in improving the overall efficiency.

Publisher Summary All beam-type pumping unit geometries fall into two distinct classes—(1) class I lever system, having rearmounted speed (gear) reducer, with the fulcrum at mid-beam and (2) class III lever system, having a push-up geometry with front-mounted speed reducer, in which the fulcrum is located at the rear of the beam.

Gas Interference in Sucker Rod Pump
AIP Conference Proceedings, 2010Commonly used artificial lift or dewatering system is sucker rod pump and gas interference of the pump is the biggest issue in the oil and gas industry. Gas lock or fluid pound problems occur due to the gas interference when the pump has partially or completely unfilled plunger barrel.

The Design of Sucker Rod Pump Systems
Proceedings of SPE Centennial Symposium at New Mexico Tech, 1989Abstract The complete design of a sucker rod pumping system is an involved trial and error process. An "optimum" design requires that the engineer specify pump size and type; rod string size, taper, and material; surface unit type and size, gear box rating, beam rating, and stroke length; and prime mover type and size.

Improving the operational conditions for the sucker-rod pumping system
2009 IEEE Control Applications, (CCA) & Intelligent Control, (ISIC), 2009In this work a new perspective of a sucker-rod pumping system control is presented. The strategy consists in associating the bottom hole pressure measurement and dynamometer cards analysis in a cascaded control. In the proposal, the widely applied control strategies based on dynamometer cards are combined with the strategy based on the measurement of ...

The Sucker-rod Pump as a Problem in Elasticity
Transactions of the AIME, 1937This paper is a progress report of a study the authors are making of thesucker-rod pump, considered as a vibrating system with one degree of freedom, with forced vibrations and with viscous damping. Dr. S. Timoshenko's formula isgiven, defining such a system.

High Volume Pumping with Sucker Rods
Journal of Petroleum Technology, 1968Abstract Recent studies have shown that often large fluid volumes can be lifted by sucker rods with great effectiveness from shallow to medium-depth wells. Wherever feasible, significant redaction in cost of elevating a barrel of fluid may be realized by the operator.
