Abstract An improved model for predicting the behavior of sucker rod pumping installations is presented. This model incorporates the dynamics of the liquid columns as well as the sucker rod string through a system of partial differential equations. This system of equations is solved by a modified method of characteristics on a digital computer. The model predicts the polished-rod and pump dynamometer cards and incorporates the effects of liquid inertia and viscosity. The model is capable of simulating a wide variety of pumping conditions for which liquid physical properties are important. The information physical properties are important. The information predicted by the model is useful in the design and predicted by the model is useful in the design and operation of sucker rod pumping installations. Introduction Sucker rod pumping is the primary artificial lift method used in the U.S. Thus, there is a need for an accurate sucker rod pumping model to assist in the design and simulation of sucker rod pumping installations. Recently there has been a substantial effort to develop sucker rod pumping models that can be solved with the aid of a pumping models that can be solved with the aid of a digital computer. These efforts, however, have been restricted solely to the analysis of the dynamics of the sucker rod string. As such, these models ignore the dynamics of the fluid and tubing columns as well as the fluid physical properties. This study overcomes one of these shortcomings by including the dynamics of the fluid as well as the rods. Thus, it is now possible to analyze the effects of fluid physical properties on a sucker rod pumping installation. The computer program for sucker rod pump system design that was written to implement the following model is very general. The program includes the effects of motor slip, different types of pumping units, various inertial effects in the surface equipment, tapered rod strings, fiberglass rods, sinker bars, unanchored tubing, gas interference, fluid pound, etc. However, the purpose of the current study is to illustrate the effects of fluid properties on a sucker rod pumping installation. As a properties on a sucker rod pumping installation. As a result, the following assumptions are made to segregate more accurately the effects of the fluid column from other effects:fluid column contains no gas,tubing is anchored, andprime mover has no slip. These assumptions are not necessary components of the model, and are used in the current study only for the purpose of illustration. purpose of illustration.

Sucker Rod Pump

AbstractIn many oil reservoirs worldwide, the downhole pressure does not have the ability to lift the produced fluids to the surface. In order to produce these fluids, pumps are used to artificially lift the fluids; this method is referred to as artificial lift. More than seventy percent of all currently producing oil wells are being produced by artificial lift methods. One of the most applied artificial lift methods is sucker rod pump. Sucker rod pumps are considered a well-established technology in the oil and gas industry and thus are easy to apply, very common worldwide, and low in capital and operational costs. Many advancements in technology have been applied to improve sucker rod pumps performance, applicability range, and diagnostics. With these advancements, it is important to be able to constantly provide an updated review and guide to the utilization of the sucker rod pumps. This research provides an updated comprehensive review of sucker rod pumps components, diagnostics methods, mathematical models, and common failures experienced in the field and how to prevent and mitigate these failures. Based on the review conducted, a new classification of all the methods that can fall under the sucker rod pump technology based on newly introduced sucker rod pump methods in the industry has been introduced. Several field cases studies from wells worldwide are also discussed in this research to highlight some of the main features of sucker rod pumps. Finally, the advantages and limitations of sucker rod pumps are mentioned based on the updated review. The findings of this study can help increase the understanding of the different sucker rod pumps and provide a holistic view of the beam rod pump and its properties and modeling.
