Quartz Gauges

Weatherford quartz P/T gauges provide pressure and temperature by using a quartz transducer which incorporates a high-temperature hybrid design. The hybrid circuit is fully contained in a custom hermetic package for operation up to 392°F (200°C) with accelerated testing as high as 437°F (225°C). The packaged quartz gauge is temperature rated to 302°F (150°C). The robust package allows operation in extremely high shock environments. Quartz resonators use the inverse piezoelectric effect to induce the resonator to vibrate at its mechanical resonant frequency when electric fields are applied to its electrodes. An oscillator circuit supplies the power and allows the frequency to be measured.

Quartz gauges are commonly used to measure the changes in the reservoir. These measurements provide the reservoir engineer with information that can be used to update the reservoir model and ultimately base recovery operations.

Instrumentation, Data Interface and Communications

Weatherford offers a full line of reservoir monitoring systems (RMS) to fit the scale and complexity of your completion projects. There is an RMS surface system for interior or non air-conditioned, even harsh environments. These systems provide web-enabled accessibility for reading on demand.

Our basic RMS provides integrated information to operators from multiple optical tools. It can operate as a stand-alone data-acquisition, management, display and communication system or it can seamlessly interface with legacy SCADA, secure intranets, Internet or communication systems. With considerable local storage available, the RMS can hold an extensive amount of high frequency data. The system features a single shared network for Modbus, TCP/IP and OPC.

The system supports a simple P/T application to multiple P/T and DTS tools. The RMS, RMS-WH (wellhead), and RMS-WH-Q (quartz) can monitor up to six optical or electronic tools.
