Wireless Instrumentation For Well OptimizationSource: Schneider Electric, Telemetry & Remote SCADA Solutions
By Denis Rutherford
The Natural Gas and Oil industry is continually driven by cost cutting measures and the need to gain more operational efficiencies and visibility to regulatory requirements. This paper summarizes a solution in which wireless instruments integrate with other conventional equipment to offer a rapidly deployable advanced well optimisation system.
Wireless instrumentation products provide cost-effective and easy to install alternatives to traditional, hardwired sensor sites. These rugged field units are designed for the majority of Oil & Gas applications and for installations ranging from general purpose to Class I Div 1 hazardous locations with extreme temperature and humidity ranges.
True wireless instrumentation is comprised of self-contained, self-powered field units providing process data to a centralized base radio through an unlicensed band, spread-spectrum, and frequency hopping wireless connection. Networks of up to 100 field units (900MHz version) can be created and polled by a single base radio using a secure, proprietary "Industrial Wireless" protocol, with a typical range between field unit and base radio of up to 3000ft (~1000m). With the capability to scale up to as many as 256 wireless instrumentation LANs, future expansion plans are easily accommodated.
