BEP-03 Combination Borehole Probe

The BEP-03 is a combination probe designed to measure a wide range of physical rock properties in a borehole. The probe is equipped with the following sensors:

  • Induction Conductivity sensor
  • 16”& 48” normal resistivity arrays
  • Temperature sensor

The BEP-03 is controlled by an on-board microprocessor, which can sample up to 10 separate sensors at a rate of 2 Hz with up to 24 bits of resolution. The sensors and the electronics is contained in a non-magnetic, non-conductive housing that is pressure rated to 2000 meters. The BEP-03 is compatible with the BIN-04 digital data interface and IFG Corporation’s standard 4 conductor logging cable.

The BEP-03 is a effective way to obtain a number of geophysical logs in a single survey run. The probe provides the measurement of inductive conductivity, galvanic resistivity and high sense temperature. The inductive conductivity sensor measures the conductivity of the rock. The high sense temperature logs can be applied for fracture mapping and water flow determination.
