This page discusses the specific artificial-lift technique known as beam pumping, or the sucker-rod lift method. Many books, technical articles, and industry standards have been published on the sucker-rod lift method and related technology.[1][2][3][4][5][6][7]Additionally, the other components of a sucker-rod pumping installation are discussed, including applicable engineering and operating information. The complete operating system should be understood and addressed to properly design, install, and operate this or any other type of artificial lift system. The Gipson and Swaim "Beam Pump Design Chain" is used as a foundation and built upon using relevant, published technology.[5][6][7] Beam pumping, or the sucker-rod lift method, is the oldest and most widely used type of artificial lift for most wells. A sucker-rod pumping system is made up of several components, some of which operate aboveground and other parts of which operate underground, down in the well. The surface-pumping unit, which drives the underground pump, consists of a prime mover (usually an electric motor) and, normally, a beam fixed to a pivotal post. The post is called a Sampson post, and the beam is normally called a walking beam.Figs. 1 and 2 present a detailed schematics of a typical beam-pump installation. This system allows the beam to rock back and forth, moving the downhole components up and down in the process.

This chapter discusses the specific artificial-lift technique known as beam pumping, or the sucker-rod-lift method. Many books, technical articles, and industry standards have been published on the sucker-rod lift method and related technology.[1][2][3][4][5][6][7] This chapter is a complete revision of previous editions of thePetroleum Engineering Handbook,[6] but it combines the prior three relevant chapters that covered downhole rod pumps and sucker rods, along with pumping units and prime movers. Additionally, the other components of a sucker-rod pumping installation are discussed, including applicable engineering and operating information. The complete operating system should be understood and addressed to properly design, install, and operate this or any other type of artificial-lift system. Thus, this chapter uses the Gipson and Swaim "Beam Pump Design Chain" as a foundation and builds on this design philosophy by using relevant, published technology and the latest industry practices.[5][6][7]

The primary surface equipment for a sucker-rod lift system is the pumping unit and itsprime mover. But a variety of other equipment is also used in the surface operations for this type ofartificial lift. This page discusses the polished rod, associated clamps, stuffing boxes, rod rotators, pumping tees, check valves, and surface valves. A polished rod is the top-most rod in a rod string. These rods come in various lengths and sizes.

While downhole pumps and sucker rods are the chief components of a sucker-rod lift type artificial lift system, a number of other components are also used in the subsurface portion of the system. These include tubing, tubing anchor-catchers, tubing rotators, sinker bars, rod centralizers, and paraffin scrapers. Tubing provides detailed information on the design, selection, and use of tubing for production wells. As related to most sucker-rod-lifted wells, the standard weight of external-upset-end, API tubing[1] should be used because of the increased wall thickness in the threaded ends. Thus, if there is rod coupling-on-tubing wear, more life and fewer leaks will be realized than if nonupset API tubing is used. Using API Grade J55 tubing, consider full-body normalizing after upsetting to prevent "ringworm corrosion" in the heat-affected upset region when the tubing is placed in corrosive (H2S or CO2) service.

Ongoing operation of a sucker-rod lift system may involve a certain amount of automation and control. Information on troubleshooting problems is also discussed. Automation means different things to different people and becomes a problem when the term triggers concern from the field about personnel reduction. Thus, sucker-rod-lift automation may not always be considered good if not properly applied. At minimum, a sucker-rod-lift installation should have vibration switches on the unit to shut it down, if there is a high part in the rod string that will cause overloading of the gearbox or damage to the unit foundation.

Replacing a rod string one rod at a time is not normally a good operating practice; thus, the economic life of a rod string needs to be considered if rods start to fail. Typically, the rod-string section will be replaced after two or three failures, while the entire rod string may be replaced after three or four failures. However, the reasons for failures need to be investigated and the root cause for this failure must be determined to extend the rod life in the future. An SPE paper by Powers[41] considers the factors that enter into the decision about when to replace the entire rod string after sustaining the calculated number of failures. Usually, wells of the same type in a field can be grouped together and the necessary calculations do not have to be performed for each well. Sufficient calculations need to be done to assess the economic impact for all wells in a field.

The prime mover (PM) rotates the gear-reducer gears through a V-belt drive. The two most common PMs are electric motors and internal combustion (IC) engines. The decision concerning which to use depends on a variety of considerations, which includes the following: * Availability of the power source (electricity or combustible fluid) * HP required to pump the well * Efficiency of the system * Ability to control the PM to match the on/off potential operation of the pumping unit * Availability of field and/or service personnel capable of maintaining and repairing the equipment * Condition of the gas (sweet or sour) or availability now and in the future of the gas or liquids (i.e., propane or diesel) if an IC engine is used * Current and future expected cost for the power source * Anticipated full-cycle total cost (including initial capital, operating, maintenance, downtime, and repairs) for the duration of the well These considerations, as well as other factors, have been discussed in numerous publications.[1][2][3][4][5][6][7][8][9][10] The characteristics of these engines are summarized here, and the detailed comparisons and field experiences have been published elsewhere.[11][12] Four-cycle, high-speed engines (greater than 750 rpm): * Best suited for portable test installations vs. permanent installations * Lower initial cost * Lower weight per HP * Wide speed and power range * Operates on a variety of fuels * Large speed variations occur during pumping cycle because of a small flywheel effect * Operates on a fixed throttle with the governor mechanism acting only as an overspeed device * Has relatively short life because of the fast moving parts and the close tolerances required * Requires frequent oil changes * Requires frequent maintenance * Major repairs require that the engine be removed from the pumping unit These test data should be requested and furnished to the purchaser from the manufacturer. The data should include the manufacturer's curves showing the torque, maximum brake HP, and the rated-brake HP vs. engine speed. These are important to know the speed range in which the engine would be able to operate. A general guide for installation and maintenance of gas engines is API RP 7C-11F,[14] which covers all three types of engines and includes a troubleshooting section. This practice should be used as a starting point for engines unless the specific manufacturer's operating manual details otherwise. Additionally, there are a number of published papers on installation, care, operation, and lubrication of engines as prime movers for pumping units.[15][16][17][18][19]
