Applications

Offshore rig at sunset.

01

For completions

The long-term stability and reliability of Quartzdyne pressure transducers are ideal for intelligent completions and permanent downhole monitoring. Our quartz pressure transducer delivers precision data that enables production optimization and enhanced recovery. Quartzdyne is the elite standard for downhole precision pressure measurement throughout the world.

Drilling a well.

02

For drilling

Quartzdyne pressure transducers are used in many different ways related to oil and gas drilling. MWD (measurements while drilling), PWD (pressure while drilling), DST (drill stem testing) and LWD (logging while drilling) applications will all benefit from the high precision of quartz.

Oil well site location.

03

For production logging

Our advanced expertise and experience with quartz crystal technology enable us to provide high-quality transducers with minimal drift at the high temperatures and pressures often found in oil and gas wells. Applications such as Memory Tools, Repeat Formation Testers, Production Logging Tools, and Wireline/Geological Logging Tools all benefit from the high sensitivity, high stability, high resolution, and fast response time these gauges provide.
