Short Description
WellLIFT N ESP Monitoring System WellLIFT N ESP Monitoring System



The Baker Hughes WellLIFTN downhole sensor system delivers critical data on pump intake pressure, intake fluid temperature, motor winding temperature, and system vibration, all aimed at increasing run life and improving electric submersible pump (ESP) system performance. The system has three parts: the downhole sensor, the surface inductor panel, and the surface electronics panel. The downhole sensor offers digital data transmission, eliminating signal interference that can cause false information and loss of downhole data.


  • Onshore mature oilfields
  • Gas dewatering
  • Oil shale


  • Factory calibration Eliminates manual installation of calibration keys or calibration data through user-friendly plug-and-play system
  • Communication over standard ESP power cable Avoids the cost of additional communications cable
  • Continuous operation when ESP power is off Provides information when the ESP is not running, offering critical data such as pressure buildup
  • Modular design of bottom of motor Improves equipment sizing and broadens applications
