Overview of the RMS-WH Wellhead Optical-Sensor Reservoir Monitoring System
Weatherford's RMS-WH wellhead reservoir monitoring system is a stand-alone surface data-acquisition system designed to monitor up to six Weatherford optical pressure and temperature gauges and provide Web-enabled accessibility to readings on demand.
With considerable local storage capacity, the RMS-WH can hold an extensive amount of high-frequency data over broad time periods. The configuration/application software is identical to that used in Weatherford's full RMS system, supporting communication protocols that conform to industry standards to ensure flexible data handling.
Applications for the RMS-WH Wellhead Optical-Sensor Reservoir Monitoring System
- Desert, arctic, and swamp environments
- Satellite platforms
- Trial projects
RMS-WH Wellhead Optical-Sensor Reservoir Monitoring System Features, Advantages, and Benefits
- External display of status facilitates system operation checks.
- Configuration of the RMS-WH by laptop computer provides convenience.
- Data are recorded 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. In addition, data can be easily retrieved if the data link is lost.
- System can support up to six pressure and temperature gauges, reducing costs by minimizing the need for additional equipment.
- Passive downhole components facilitate upgrading of the system hardware and software as enhancements become available, improving overall sensing system performance.
- The RMS-WH is designed to function efficiently in locations where environmental protection, central power, and communications are limited or unavailable. An environment without controlled air will not affect the local storage capacity of the system or the ability of the system to deliver Web-enabled, on-demand access to readings.
- The RMS-WH is Zone 2 certified. Zone 1 certification is available on request.
