Rod Pump & Electric Submersible Pump (ESP)
Inside this lesson
- Describe the sucker-rod (beam) pump: a surface pumping unit reciprocating a rod string that drives a downhole plunger pump
- State that the rod pump suits low-to-moderate-rate, shallow-to-mid-depth wells, and that the surface dynamometer (pump card) diagnoses downhole conditions conceptually
- Describe the electric submersible pump (ESP): a multistage centrifugal pump run downhole on power cable
- Contrast rod pump and ESP selection by rate, depth, free-gas content, and solids or scale sensitivity
