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.

Special types of sucker-rod pumps
Chemical and Petroleum Engineering, 2008New types of oil-well sucker-rod pumps developed by Ekogermet-M for oil production are described. All of the major units of these series-made pumps, namely, valve pairs and components, filters, draining devices, and casings of the pumps, have been improved.

New Tubingless Sucker Rod Pump System in Slim Holes
Proceedings of Production and Operations Symposium, 2007Abstract In this paper, slim hole refers that the nominal diameter of production casing is less than 5 inch. In many problem wells, production casing is destroyed and new casing is reinstalled to continue oil production. And sidetrack drilling in old well is an effective method to find residual oil.

New Concepts in Sucker-Rod Pump Design
Journal of Petroleum Technology, 1969New streamlined sucker-rod pumps improve production performance of viscous crude wells in Venezuela. The simple two-stage version further improves the volumetric and power efficiency and minimizes pounding, gaslock and rod fall problems. pounding, gaslock and rod fall problems.
