Downhole pressure and temperature gauge SAMT-02

SAMT-02 downhole pressure and temperature gauge is a completely autonomous tool (so-called deep action tool) designed to measure pressure and temperature in the wellbore of an oil or gas well and/or monitor pressure and temperature changes at any point, e.g., on the wellhead during a pressure buildup test.

 

Applications

  • Pressure Gradients
  • Production Tests
  • Build-up Pressure Tests
  • Injection Pressure Tests
  • Drill Stem Tests
  • Interference/Pulse Tests
  • Frac Monitoring
  • Post Stimulation Evaluation
  • Gas lift optimization
  • Perforation Monitoring

 

Features

  • Operating in several modes, having various measuring time steps (from 128 time per 1 second to 24 hours)
  • Large memory capacity - 2 170 000 data sets that can be assigned to 16000 survey protocols
  • To program operating mode, to collect measured data no need to disassemble tool
  • Flexible software, capable of setting the tool mode and switch-on time, checking battery capacity and memory, downloading data to a PC, viewing and printing out measured data as tables or charts.
  • Information can be stored in tool’s memory for more than a year.
  • Measurements can be started at a set value of time, pressure or temperature.
  • Special software DB SIAM for storing and processing data.
