What Is Quartz Pressure Single Sensor Tool?
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 tests. QPS 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.
