HFP-2293 Heat Pulse Flowmeter



The HFP-2293 Heat Pulse Flowmeter is a unique flowmeter tool designed to measure low flow rates in the borehole environment.  It will also give the direction of the flow of fluid vertically. To detect these low flow rates, measurements must be made while the probe is stationary at different depths within the borehole. The probe is run standalone.

Matrix Heat software is used with the HFP-2293 and is compatible Matrix Logging Systems. Individual heat-flow waveforms can be saved, and text files with depth and flow rate can be imported into WellCAD for a histogram-type presentation.


  • Measure interval and/or fracture-specific low flow rates
  • Identification of hydrostratigraphic units
  • Determine transmissivity and hydraulic head
  • Confirmation of predicted transmissive zones in open hole
