Sucker Rod Pumping Systems Design -Another Look

ABSTRACT This paper presents a computer generated three dimensional design profile of gear box torque, maximum rod stress, and peak beam load as a function of pumping speed and pumping depth. This approach can be used to quickly define the optimum operating limits of any beam pumping system. It can also be used to compare various design methods, operating conditions, and pumping system configurations. The three dimensional profiles shown in this paper are accompanied by a comprehensive review of pumping unit types and design methods. A calculational technique is also suggested as an approximate guide to the use of new pumping unit geometries.
