Overview of the Optical Pressure-Temperature Gauge

Weatherford's optical pressure-temperature (P/T) gauge provides permanent reservoir monitoring, enabling superior reservoir management decision-making.

Operating reliably in high-temperature/high-pressure (HTHP) applications, the optical P/T gauge delivers stable, high-resolution reservoir pressure and temperature measurements with no measurable drift. Its unique operating capabilities offer a performance margin for high-value wells.

Applications for the Optical Pressure-Temperature Gauge

The gauge is designed to provide life-of-field, reliable service and can be used in the following applications:

• In-well flowing pressure measurement
• Reservoir pressure determination during shut-ins
• Data gathering for pressure transient analyses (skin, permeability, and reservoir boundary determination)
• Management and control of well ramp-up
• Interference testing and reservoir connectivity determination
• Seamless integration with other Weatherford optical sensors
• Intelligent wells
• Subsea wells

Optical Pressure-Temperature Gauge Features, Advantages, and Benefits

• Optical technology platform enables gauge design with a minimal number of component parts and no moving parts to ensure reliable operations over the life of the well.
• Gauge is designed to deliver stable measurements with no measurable drift, eliminating concerns about absolute pressure and temperature measurement over the life of the field.
• Gauge has the industry's highest mechanical shock and vibration survivability, enabling it to withstand impact, vibration, and significant pressure surges.
• Immunity to electromagnetic interference means functionality will not be disrupted by other electrical completion components.
• Complex interrogation components are located at the surface, making the gauge system easy to service.
• Gauge is chemically inert, minimizing corrosion compatibility concerns.
• On-demand availability of reservoir pressure data reduces well interventions and production shut-ins.
• Gauge is electronically passive, with no electronics downhole, increasing system reliability and stability.
• Gauge features a standard footprint and gauge mandrel interface and requires no more than industry-standard handling and installation procedures, for minimal effect on the completion architecture.
