... Abstract Artificial lift and particularly sucker rod pumping units are the most applied technologies for oil wells. While the equipment as such requires strong mechanical background, the use of the equipment remains solely the responsibility of petroleum engineers. Teaching them the working...

... Abstract Worldwide, as conventional oil resources are depleted; reciprocating sucker rod pumping systems are becoming the most common type of artificial lift methods for onshore wells. With the growing number of sucker rod pumped wells, the value of optimization and cost control...

... The goal of building an ontology was to provide basis for the development of an expert system to assist sucker rod pumping failure diagnosis and wells degradation severity level classification. Figure 1 illustrates the SRP ontology. Nodes represent the main concepts and the links represent...

... Abstract Engineers have used standard techniques for decades when analyzing sucker rod wells, such as: API 11L standard, wave equation numerical simulation, acoustic logs and dynamometer card acquisition and processing. Each technique has a particular goal and they complement each other. API 11...

... Abstract Beam pumping systems are the most commonly applied worldwide artificial lift method with 59% of all Artificial Lift in North America and 71% of 832000 wells for the rest of the world (World Oil 2000). This paper reviews many of the concerns that operators face when using the sucker rod...

... along the rods. For the sucker rod problem the damping law in the wave equation was chosen primarily for mathematical tractability even though it did not rigorously mimic the real dissipation effects along the sucker rod. The boundary value problem that led to computation of downhole pump...

... Abstract Mean time between failure (MTBF) has been the standard for tracking field performance of sucker rod pumped wells but it can lead to improper conclusions and applications. A new method using cycle time and loading can greatly improve the understanding of the true performance of sucker...

... Abstract In oil wells with beam pumping systems, sucker rods mainly failed by fatigue due to the fact that they operate under cycling tension stresses. Additionally, superficial defects could be generated during handling and operation of the rods, which favor the formation of fatigue cracks...

... The Guando oil field, located in Tolima, Colombia, and operated by Petrobras Colombia Ltd., has been developed with S-shape deviated wells, completed with progressing cavity pump (PCP) systems that are driven by centralized conventional sucker rod string. The increase in sucker rod failures that has...

... Abstract In Daqing Oil Field, after polymer flooding, severe eccentric wear of sucker rods and tubing in many wells with pumping units have occurred. The life span of the tubing string has decreased from 750 days for lifting fluid that does not contain polymer to 270 days for fluid...

... and equipment, points out the influence that the special rheologic characteristics, especially the viscous-elastic nature of the fluid, has on the system and the modification made. For example, there is a normal force acting on the beam pump sucker rods that cause pronounced eccentric mechanical wear on one...

... Abstract Sucker rod pumping is the most popular form of artificial lift in the Permian Basin, which is one of the largest petroleum production basins in the United States.This paper is part of the research results of the Artificial Lift Energy Optimization Consortium (ALEOC),a research project...

Abstract Sucker rod pumping system is a very important artificial lift method. The surface dynamometer card (SDC) is a plot of the load versus the pumping cycle measured...

... ABSTRACT The ability of a sucker rod to last in a well lifted with beam pumped equipment depends on many factors. One of the principle factors is the fatigue life of the rod. Previous rod life expectations are based on the modified Goodman Diagram that resulted in the expected life...

... Abstract In an effort to reduce well failures, Mobil elected to investigate the reasons for rejection rates in new sucker rods. Independent third party inspections indicated a combined 14.3% rejection rate for new sucker rods from all manufacturers during 1990. Inspection results indicated...

... Abstract In 1985, a silicon-controlled rectifier (SCR) device was installed on a sucker rod pumping well in the North Hobbs Unit, New Mexico, to eliminate a potentially severe structural shaking on unit start-up. On the basis of limited tests on this unit that indicated possible power savings...
