Mainly due to its long history, sucker-rod pumping is a very popular means of artificial lift all over the world; roughly two- thirds of the producing oil wells are on this type of lift. To maximize profits from these wells in the ever-changing economic situation with rising costs of electric power, installation designs must ensure optimum conditions. QRod is the most widely used, program for the design and prediction of the performance of Sucker Rod Beam Pumping Installations. The QRod version for the PC can be used free of charge. The software can be downloaded for installation and use on any numbers of PCs. The program uses a wave equation solution to accurately predict the surface dynamometer loads, gearbox torque and pump capacity, with a minimum amount of input. The effect of changing a parameter such as tubing anchor, stroke length, stroke rate and pump diameter can be immediately seen in the dynamically updated plots. After a review of the surface and downhole energy losses in sucker-rod pumped wells, some key considerations on the ways to improve system efficiency are given. The most important task is the proper selection of the pumping mode, i.e. the combination of plunger size, pumping speed, stroke length and rod taper design for lifting the prescribed amount of liquid to the surface. The paper gives aspects and details of optimizing sucker rod pumping operation by using QRod simulator along with practical
