Suspended system

Unlike a conveyed Reservoir Group system, a suspended system is installed without the requirement of a service or drilling rig.

Developed and manufactured internally, the key items consist of:

  • Surface Electronics (DINLine)
  • Wellhead Feed-Thru (CSA, UL Class 1, Div2 approved)
  • Cable Heads (fully pressure testable with Strain relief)
  • Downhole Instrument Cable (TEC) (0.125” Inconel and 316Stainless)
  • Downhole Sensors (Piezo, Quartz, Piezometer, Thermocouple, RTD)



As with a Conveyed system, particular attention goes into designing a Suspended Monitoring system. Most often, these require custom design as a result of the unique characteristics of each completion and wellbore configuration. Maximum run depths approach 3500 meters with wellbore environments of around 250°C.

Reservoir Group Oil & Gas has consistently led the industry in the permanent monitoring segment, with over 1200 installations globally and a success rate of greater than 97% over the past 5 years. This success can largely be attributed to our attention to detail around our clients expectations and deliverables.
