Quartz Pressure Single Sensor (QPS)
The Quartz Pressure Single Sensor Tool (QPS) is used to provide a continuous log of borehole fluid pressure and to record reservoir pressure draw-down and build-up data during flowing testsThe Sondex Quartz Pressure Tool measures pressure and gauge temperature using an industry standard precision quartz crystal pressure transducer.
A Quartzdyne® pressure gauge, with removable bellows to isolate the quartz crystal from well fluids, is fitted to the lower tool body. An open pressure port with wire mesh filter allows well pressure into the gauge. A second (flushing) port is plugged while the tool is running in hole.
