There has been the concept that a long stroke and slow pumping speeds are the best way to design sucker rod lifted wells. Typically, longer fatigue life is one of the reasons to rationalize this practice. Additionally, slow versus fast pumping speeds are relative numbers. This paper will discuss the various operating concepts, the background on pumping equipment capabilities, maximum design considerations and provide rod string design comparisons showing rod loading and power comparisons resulting in new considerations for optimizing sucker rod lifted wells.
