Sucker rod pumping is the most common type of artificial lift systems deployed in oil and gas wells to improve production. The sucker rod string, which is the component that transfers the reciprocating movement of the surface polished rod to the downhole pump plunger, is the source of many operational complications. From damaged rods and unscrewed couplings to time-consuming rod attachment/detachment procedures, the influence of these failures on the operational costs is substantial. Hence, continuous strings like wire ropes and synthetic ropes can be a convenient replacement for the conventional rod string. In this work, the performance of a wire rope, designed by Voestalpine Company as well as a Dyneema® fiber rope designed by DSM are analyzed and simulated with a computer software package. The results prove that the efficiency of both designs highly depend on the geometry of the well, type of the pump and the surface structure. They also show that pumping with wire or fiber ropes can be just as productive, or surpasses the efficiency of a conventional sucker rod string as long as certain measures, such as material tensile strength and pumping SPM, are taken into advisement.
