WellLIFT H ESP Monitoring System WellLIFT H ESP Monitoring System



Baker Hughes Monitoring and Automation services provide operators with insight into the information required to optimize production and extend system run life. The WellLIFT™ H down-hole sensor system was designed by experts with more than a decade of experience in the design and supply of downhole sensors.


  • Offshore oilfields
  • New drills / completions
  • Gas dewatering
  • Oil shale


  • Three independent, optimally placed temperature sensors – Deliver temperature readings with accuracy and responsiveness for the pump intake, sensor electronics, and motor winding
  • Factory calibration – Eliminates manual installation of calibration keys or calibration data through user-friendly plug-and-play system
  • Electron beam (EB) welded design – Provides reliability against leakage for prolonged gauge life – Offers the most robust and reliable design on the market for critical wells
  • Hydraulic discharge pressure monitoring system – Offers maximum value in ESP monitoring with industry-leading electronics and a traditional hydraulic discharge pressure measurement
  • Continuous, four-second intake pressure update rate – Provides valuable insight into reservoir and pump performance with the industry’s fastest, most accurate temperature corrected intake pressure
  • Extensive surface diagnostic capabilities – Includes self-diagnostic capabilities that help increase production, decrease downtime, and lower OPEX
