Product Description

Designed for permanent installation in oil and gas reservoirs, Roxar Downhole Pressure and Temperature Gauges feature quartz crystal measurements for reliable operation in the most extreme well conditions. The gauges continually transmit digitized pressure and temperature data to the surface from any reservoir location, empowering operators to make fully informed decisions throughout the well's lifetime.

Features

  • Measure far beyond hybridized electronic gauge limits with Silicon-On-Insulator (SOI) technology accurate up to 225°C (437 °F) 
  • Ensure long-term low-drift reading accuracy of bottom-hole temperature with quartz crystal measurements 
  • Can be flexibly deployed for production, injection and observation wells, as well as in highly complex multi-zone intelligent wells
  • Strengthen decision-making with integration with Emerson’s production-management system, Roxar Fieldwatch 
  • Rely on downhole gauge carriers tailored specifically to Emerson’s Roxar downhole pressure and temperature sensor portfolio 
  • Installed with mono Tubing Encapsulated Cable (TEC), alternatively using twisted pair TEC for long reach and to create fully isolated circuit in wells with electrical noise (ESP applications).
