AbstractWorldwide there are almost 920,000 producing oil wells, about 87 % of these wells are operated using different artificial lift methods and roughly distributed as: 71 % are producing using beam pumping system, 14 % using electrical submersible pumping (ESP), 8 % using gas lift and 7 % using all other forms of lifting systems.This study was undertaken using advanced predictive methods, high strength rods, optimum pumping mode, and unit geometry to optimize the performance of beam pumping system for deep high volumes oil wells. Three geometries of different surface pumping units were analyzed and studied including, conventional, Reverse Mark and Mark II units. Each geometry of these three types has been subjected to different design features that affect torque and different linkages affecting its kinematics behavior. The highest strength sucker rod string, beam unit geometry, stroke length, pumping speed and subsurface pump size were varied and analyzed jointly to obtain optimum pumping parameters capable to produce maximum fluid at different well depths. This study considered and applied many variables including; well depths from 1,000 to 15,000 ft, three different rod grades, water cuts from 0.0 to 100 %, different pump sizes from 1.25 to 5.75 in, stroke lengths from 100 to 260-inch, and non-API sucker rod grades.The results indicated that the lifted liquid volumes and pump seating depths for deep wells can be effectively increased using the beam pumping systems. The surface unit geometry has shown a crucial effect of increasing the produced quantity from deep wells. The study recommended using conventional pump unit for shallow depths up to 8,000 ft. The enhanced geometry pumping units of Mark II and reverse Mark have been proven the superior type for deep high volumes wells because it required the least torque to lift the same quantity from different well depths. The study also presented successful field applications for deep wells producing high volumes.

Worldwide, as conventional oil resources are depleted, the reciprocating sucker rod pumping systems recognized as the most widely applied mean of artificial lift system for onshore wells. The popularity of this system is attributed to its durability, simplicity, and flexibility. The advanced technologies in surface and downhole equipment overcome many of the old problems, such as; producing difficult fluids (high gas and/or sand, corrosive fluids and heavy crude) and producing unconventional wells. The necessity to maximize production and produce difficult fluids in higher economic efficiencies for rod pumped wells has created a high demand for ultra-long stroke lengths and high capacity units. The reasons behind that are the advantages of using this type of surface pumping units as compared with conventional beam units. This system allow for producing greater liquid rates with less downhole pump/rods/tubing problems. This increases the mean time between failures (MTBF) due to the reduced number of stress reversals, peak load and stresses (total amount of rod stretch caused by the load differentials between minimum and maximum polished rod loads). This paper will present the new intelligent long stroke reciprocation pumping system for well production & cost optimization and produce difficult wells and/or fluids. This is additional to enhancing the safety by reducing the well site operations to change well running parameters for well optimization. All will perform automatically without relying on manpower interference at well-site. This achieved by the World's Longest Intelligent sucker rod unit stroke length (up to 372 inch) with highest lifting Capability up to 80,000 lbs. The system is fully Automatic/Independent Variable Speed Up or Down and control pumping speed with and integrated expert supervisory control. Also it will highlight the benefits achieved by applying the up-to-date in reciprocating pumping technology as well as the use of expert supervisory control which analyzes the wells using intelligent artificial lift system. Actual well data will be shown from successful field results. The application of this novel technology will help to:Allow to produce high volume from deep wells.Reduce OPEX by Minimize Well InterventionsDue to the long slow stroke and soft turn-around and less friction between the rods and tubing will greatly decrease side loading. Also the fewer Cycles will Extended BHP, tubing and sucker rod lifeEqual or provide greater production at a Lower SPM
