PPS71 Elite Geothermal Tools
Brand: Pioneer Petrotech Services IncThe PPS71 Elite 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 rays, and can be configured as either a memory tool or surface read out tool (SRO) tool. The measurements are done with a highly accurate silicon-sapphire (piezo) transducer, a fast response resistance temperature detector (RTD), either a continuous or full bore spinner flowmeter, magnetic CCL and sensitive gamma ray crystal which detects incoming gamma rays from the formation.
FeaturesOperating temperatures up to 350 degrees Celsius
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
