Heavy oil reservoirs have become one of the most important energy sources lately. However, the consumption of these sources requires special methods due to the heavy oil conditions. Therefore, various mechanical methods were used, including sucker rod pumps that were able to deal with heavy oil until A certain degree of viscosity causing frequent interruptions of the pumping rods as a result of the tension and contraction of these rods during the up and down stroke. In addition to this, the low production rate of heavy oil, so in order to deal with this problem, the technology has turned towards progressive cavity pumps .in this paper will highlight of the SRP/PCP where this research aims to use progressive cavity pump units as an alternative to sucker rod units for heavy oil production and economic comparison was made between them in terms of costs, operating requirements and the time period required to recover these costs. results have shown the superiority of progressive cavity pumps in term of performance and 50% of the costs of sucker rod pumps were sufficient for the application of progressive units and these pumps were able to achieve significant economic savings compared to sucker rod units.

“…The stator is usually made of rubber [6,7], and the rotor is made of steel, often superficially hardened. The exploitation activity of the pumps with progressive cavities has highlighted the fact that traditional pumps with a rubber stator, which surrounds the rotor, do not allow the existence of an interstice between them, which limits their activity until the stator wears out [8,9]. Alternatively, a new class of pumps that do not use elastomers has been developed, in which the rotor and the stator are made of metal, and are used in drilling activities in high temperature wells [10][11][12][13].…”

Progressive cavity pumps are used in industry for the circulation of high viscosity fluids, such as crude oil and petroleum products, sewage sludge, oils, salt water, and wastewater. Also known as single screw pumps, these pumps are composed of a single rotor which has the shape of a rounded screw, which moves inside a rubber stator. The stator has an double helical internal surface which, together with the helical surface of the rotor, creates a cavity that moves along the rotor. The movement effect of the cavity inside the stator is the movement of the fluid with a constant flow and high pressure. In this paper, an algorithm for profiling the rollers for generating the helical surface of the pump rotor with progressive cavities is proposed. These rollers are constituted as tools for the plastic deformation of the blank (in case the pump rotor is obtained by volumetric deformation) or for its superficial hardening.

“…In petroleum industry piston pumps (PP) and progressive cavity pumps (PCP) are largely used. The pumped fluid contains formation water, solid particles, dissolved gases such as O2, CO2, H2S, salts and chlorides all increasing fluid aggressivity, [1,2,3,4]. In acidization operation with PP are inserted in well acids to stimulate the formation deposits and to increase the well production.…”

The progressive cavity pump (PCP) is a positive displacement pump, consisting of a polished helical-shaped rod (rotor) turning inside a helical elastomer (stator). PCP has many advantages, but the pump durability is manly limited by elastomer behavior. At piston pumps (PP) used for drilling mud piston has an elastomer sleeve that also limit the durability. Standards like ISO 15136.1 & 2 for pumps developed by manufactures and users’ committees provides requirements for design, quality design verification etc., but do not define specifically the elastomer for the stator or the metal used for the rotor. Each PCP and PP manufacturer used specific materials at pump construction. The aim of this study was to evaluate the tribological behavior of some elastomers such polybutadiene rubber (BR), polybutadiene acrylonitrile rubber (NBR), polybutadiene acrylonitrile carboxylate (XNBR) and polyamide (PA 6) in couples with hard chromium coated steel, nitride steel and cast iron. Were determined friction coefficients and wear on 2 types of friction couples (plane to plane and shoe to plane) on two tribometers and some mechanical proprieties (Young’s modulus, ultimate tensile strength, elongation, hardness).
