pressure temperature spinner (PTS) tool

We’ve been building and operating downhole geothermal Pressure Temperature and Spinner tools used in geothermal investigation and well testing for almost 30 years.  This experience provides us with unique insights into where our PTS tools need to be to satisfy our clients with accurate, reliable and timely data.  Our purpose built surface read out hardware and software is synchronized with the PTS tool.

What does it do?

  • Our PTS tool is designed to continuously measure and record downhole temperatures, pressures and flows in geothermal wells.
  • The tool is capable of operating in an environment with temperatures up to 350°C and pressures up to 350 bar.
  • The PTS tool can be used on mono conductor cable in e-line mode with real time data to surface, or on slickline in memory mode.  In memory mode, the logged data is downloaded to a laptop at the surface and merged with the logged surface parameters.  Logged data remains in the tool memory until it is cleared by the operator.
  • Interchangeable spinner impeller allows impeller selection to suit the flow conditions.


The PTS tool is suitable for production testing, reinjection testing and for logging shut geothermal wells.

Features & Benefits:

  • The surface read out software has a user configurable graphical plot; the y-axis can be alternated between depth and time, providing a valuable tool for real time analysis of well survey data.
  • Runs on standard mono conductor wirelines and slicklines without requiring reconfiguration the tool electronics.
  • 3 spinner channels, offering increased reliability and confidence.
  • A high resolution, fast response, robust pressure transducer (quartz crystal sensor element) which is also temperature compensated for gathering very accurate pressure gradient data.
  • Memory operation provides alternatives to temperature limits and cost of e-line operation.
  • Calibration data for temperature & pressure is stored permanently in the tool.
  • Sampling rate of 4 readings per second.
  • Can be run as a PT tool without a spinner.
  • Easy to service and maintain.
