Overview of the RMS Lite Optical-Sensor Reservoir Monitoring System

Weatherford's RMS Lite is a basic-level surface data-acquisition system, designed to monitor up to three Weatherford optical pressure/temperature gauges and distributed-temperature-sensing (DTS) systems and provide Web-enabled accessibility to readings on demand. With considerable local storage capacity, the RMS Lite can hold an extensive amount of high-frequency data over broad time periods. This system offers a cost-effective alternative for experiencing the benefits of in-well optical permanent monitoring systems.

Applications for the RMS Lite Optical-Sensor Reservoir Monitoring System

  • Offshore and onshore developments with air-conditioned control rooms
  • Trial projects, appraisals, or small unit counts
  • Enhancement of DTS monitoring applications
  • Seamless integration with intelligent completion hydraulic control panels

RMS Lite Optical-Sensor Reservoir Monitoring System Features, Advantages, and Benefits

  • The RMS Lite is designed to record data at the highest density, even if only a slow update rate is sent to the production facility's control system—enabling detailed analysis of any production anomalies.
  • A network hub, floppy disk, and CD burner are included, reducing startup costs.
  • A small footprint makes the RMS Lite system ideal for space-limited facilities.
  • The RMS Lite offers support for up to three optical pressure/temperature gauges, reducing costs by minimizing the need for additional equipment.
  • The RMS Lite can be used to support DTS by simply adding a DTS interrogation module and an optional optical switch.
  • Passive downhole components facilitate upgrading of system hardware and software as enhancements become available, improving overall system performance.
  • The operator can view real-time and historical data or demand, through a Web browser, enabling production optimization.
