Real-time sampling of pressure and temperature

PPS 26 SRO Memory Gauge

PPS26 Surface Box PPS26 Surface Box

The PPS26 Surface Readout (SRO) Gauge is designed for real time sampling of pressure and temperature data for applications focused on production optimization, well stimulation or reservoir development. Due to the gauge’s stability and strong transmission distance, the PPS26 can send data from downhole to surface through one single conductor wireline cable at well depths up to 7,000 meters.

The SRO Box and Portable Box are designed for PPS SRO (Surface Read-Out) gauges to complete wireline field operations or operation monitoring during PDMS (permanent downhole monitoring system) field installation.
