Delivering reliable and accurate reservoir data

In today’s challenging environments, there is an increasing need for reliable and accurate reservoir data, driving the need for continuous improvement of monitoring technology. The ERD and ERD-HT downhole gauge systems provide real-time downhole data. These latest additions to the DataSphere® permanent monitoring suite provide a unique level of performance bridging an area of application between quartz and piezo gauges. 

ERD (Electrical Resonating Diaphragm) gauge sensor technology and sophisticated surface electronics eliminate the need for downhole electronics. Typical applications for the ERD system include single and dual zone monitoring. These gauges may be ported to tubing, annulus, or control line.

Monitoring Applications

  • Real-time production 
  • HPHT environments 
  • Artificial lift 
  • Unconventional 
  • Thermal observation wells 
  • Water and CO2 floods 
  • Tight gas

Gauge Features

  • ERD technology 
  • Maximum of up to 260˚C operating temperature 
  • Superior shock and vibration performance 
  • 1.0-in. OD slim line design

Benefits

  • High accuracy – superior to non-quartz offerings on the market 
  • Field-proven reliability 
  • Provides optimized production management 
  • Enables optimization of wells with commingled zones 
  • Identifies the continuity and communication between wells 
  • Assists in well placement 
  • Provides accurate data to build reservoir model
