Quartz Pressure & Temperature Module
Continuous downhole pressure and gauge temperature measurement for pressure transient testing, gradient surveys and production logging.
The Quartz Pressure & Temperature Module (QPT) provides continuous wellbore pressure measurements during logging passes, pressure build-up and drawdown surveys. Its Quartzdyne® quartz pressure transducer combines measurement precision with repeatability and long-term stability.
A bellows design isolates the pressure transducer from well fluids. The module also measures gauge temperature, supporting pressure transient analysis and gradient surveys.
