Malega Energie Service now offers downhole gauges that digitize pressure and temperature data downhole and then transmit to the surface using a high speed, digital telemetry link. Gauges available include:

  -> Roxar Gauges, the proprietary high pressure, high temperature permanent monitoring system

  -> Permanent Sapphire Pressure Gauges, which uses proprietary piezo-resistive technology

   -> High Temperature Permanent Quartz Pressure Gauge which uses a high-resolution digital quartz pressure transducer with proprietary hybrid technology



          -> Working Pressure Ranges: 10k psi, 16k psi, 20k psi

          -> Operating Temperature Range: 25-180°C (77-356°F)

          -> Inconel 718 fully welded

          -> TEC Configuration: 1/8” or 1/4” TEC


          -> 100% welded gauge Argon-filled design with testable redundant metal-to-metal seal cable head

          -> H2S and CO2 corrosive resistant

          -> Hybrid electronic technology for long-term stability and reliability

          -> Capable of either Annular or Tubing measurement



          -> Working Pressure Ranges: 6k psi, 10k psi, 15k psi

          -> Operating Temperature Range – 25-100°C (77-212°F), 25-150°C ( 77–302°F)

          -> Inconel 718 (H2S high CO2) or 17-4PH

          -> Fully welded corrosive resistant alloy (based on material selection) design

          -> Redundant pressure testable metal-to-metal cable head

          -> The system requires 24 VDC to operate


      -> Piezo Hybrid Gauges – based on Silicone Sapphire Piezo-Resistive transducer to deliver near Quartz performance at a lower cost.

          -> Suited for long-term data quality and reliability.

          -> The SAU can be powered using grid power or solar power.



          -> Working Pressure Ranges: 20k psi, 25k psi

          -> Operating Temperature Range: 25-225˚C ( 77–437˚F)

          -> Gauge Construction: INC 718 - H2S high CO2


        -> Enhanced SOI circuits for high temperature environments and Electron Beam welded modules for life of well performance.

          -> Reliability focused design.

          -> Flexible Interface to 3rd party sensors.

          -> H2S and CO2 corrosive resistant.

          -> Built Around the Versatile Roxar Downhole Interface Module (RODIM™).

          -> Enables other Roxar measurements such as Watercut, Density and Velocity.
