PPS71 Quartz Geothermal Tools
Brand: Pioneer Petrotech Services IncThe PPS71 Quartz Geothermal Tools are designed for extreme, high temperature downhole conditions.
The robust electronics combined with vacuum flask technology allow these products to perform at 350 °C (662 °F) continuously, for four hours.
The tool measures pressure, temperature, casing collar location, flow profile and gamma ray, and can be configured as either a memory tool or surface read out tool surface read out tool (SRO) tool.
The measurements are done with a superior quartz transducer, a fast response resistance temperature detector (RTD), either a continuous or full bore spinner flowmeter, magnetic CCL and sensitive gamma ray crystal.
By combining the downhole measurements with PPS’s DepthWatcher (PPS36), a depth versus time recorder, customers have the capability to create synchronized profile logs which have many applications for the end user such as monitoring radioactive tracers in injected fluids, interpreting lithology, estimating shale volume and correlating cores with logged depth.
Features- Operating temperatures up to 350°C (662°F)
- Fast response RTD temperature sensor
- Continuous or full-bore spinners are available
- Operates in either memory or surface read out mode
- Surface read out mode using e-line is compatible with the Warrior or PPS SRO acquisition system
- Can be combined with PPS36 DepthWatcher if depth measurement is needed
