Downhole monitoring systems for rod-pumps/ PCP/gas lift or flowing wells

IRZ PERMANENT DOWNHOLE GAUGES allows for real-time monitoring of Rod Pump / PCP Units, or Gas Lift / Flowing Wells in terms of tubing and annulus pressure, annulus temperature, and tubing X, Y, Z-axis vibrations. The product range covers standard and high temperature (Quartz) gauges.

Features

  • Accurate monitoring
  • High data update rate
  • Field proven fail-safe design and hi-rel components
  • The high-accuracy quartz gauge is available for high-temperature applications 200 °С and 230 °С
  • Compact sizes (ø 28 mm)
  • Resistance to H2S environment (upon request)
  • Optional metal-to-metal sealing to ensure gas protection
  • Wide DH pressure range up to 8700 psi
  • Compatible with any drive and SCADA systems using MODBUS communication protocol

Main components

  • Downhole gauge
  • Surface Readout Unit for installation inside motor drive enclosure or stand-alone surface panel
  • Fastening accessories for downhole gauge, i.e. gauge carrier and clamp
  • Downhole cable (optional)
  • Wellhead feedthrough (optional)
