BEP-02  Combination Borehole Probe

The BEP-02 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
  • Natural gamma (Total count and KUT)
  • Temperature sensor

The BEP-02 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 are contained in a non-magnetic, non-conductive

housing which is pressure rated to 2000 meters. The BEP-02 is compatible with the BIN-04 digital data interface and IFG Corporation’s standard 4 conductor logging cable.

The BEP-02 is a cost-effective way to obtain a number of geophysical logs in a single survey run. The probe provides the measurement of 4 channel radiometric, inductive conductivity and high sense temperature. The gamma sensor is a single crystal CsI(Na) detector with a dimension of 25mm X 75mm. The radiometric channels are total count , K40, Bi214 and Tl208. 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.
