Downhole Memory

Pressure-Temperature Gauge zPas-20M is based on quartz resonator and high accuracy electronics achieving a stable and highly resolving pressure (20 Pa) and temperature (0.001 C) measurements which are normally required for long-term cross-well pressure interference tests or low drawdown pressure tests in gas wells

Downhole Memory Flowmeter zFlux-1M is based on thermoanemometer sensor with advanced noise suppression and calibration methodology and provides long-term (up to 3 months) flow records which are normally required for cross-well pressure interference tests.
