Quartz Pressure Tool


Provides wellbore pressure and gauge temperature


Applications

  • Fluid identification, contacts, and densities


Features and Benefits

  • Combinable with all high-speed digital (HD) telemetry tools for comprehensive evaluation
  • Accurate across broad pressure range
  • Compact, versatile, and robust


Tool Description

The Weatherford quartz pressure tool uses a precision digital quartz pressure transducer to provide wellbore pressure and gauge temperature. This transducer provides continuous measurement of well pressure during dynamic passes, or dynamic pressure build-ups or drawdowns.
