Overview of the Optical-Sensor Reservoir Monitoring System RMS and RMS-MR Models
Weatherford's RMS and RMS-MR reservoir monitoring systems are surface data-acquisition systems designed to monitor optical sensors installed in multiple wells and provide Web-enabled accessibility to readings on demand. With considerable local storage capacity, the systems can hold an extensive amount of high-frequency data over broad time periods.
The modular design of these systems allows expansion of the number of pressure and temperature gauges to meet application requirements. Both models accommodate other sensor types, such as distributed-temperature-sensing (DTS) and flow and phase-fraction sensors. In addition, the RMS and RMS-MR systems were designed to be scaleable so that sensor interrogation modules can be added as required.
Applications for the Optical-Sensor Reservoir Monitoring System RMS and RMS-MR Models
- Offshore and onshore developments with air-conditioned control rooms
- Multiple-gauge installations
- Permanent DTS monitoring
- Seamless integration with intelligent completion hydraulic control panels
Optical-Sensor Reservoir Monitoring System RMS and RMS-MR Models Option Features, Advantages, and Benefits
- The operating software is designed for maximum flexibility and requires no custom programming, simplifying operations.
- All output options and setup configurations can be performed at the well site for operational efficiency.
- Modular design allows phased expenditure for multi-well and multi-sensor projects, which spreads commercial commitment and client expenditure over time.
- Systems are 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.
- Systems can be used to support DTS by simply adding a DTS interrogation module and either a 9- or 18-position optical switch. This versatile system can also support up to eight flowmeters and phase-fraction meters by adding a Rheos™ module.
- Passive downhole components facilitate upgrading of the system hardware and software as enhancements become available, improving overall sensing system performance.
- The operator can view real-time and historical data through a Web browser on demand, enabling production optimization.
