BMP-03 Multi-Parameter Borehole Probe
The BMP-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:
- 3-component magnetometer
- Magnetic susceptibility sensor
- 16”& 48” normal resistivity arrays
- Tilt sensor
The BMP-03 is controlled by an on-board microprocessor, which can sample up to 8 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 BMP-03 is compatible with the BIN-04 digital data interface and IFG Corporation’s standard 4 conductor logging cable.
The BMP-03 is a cost-effective way to obtain a number of geophysical logs in a single survey run. The probe provides electrical and magnetic logs for lithology mapping. The three-component magnetometer is for the measuring of the total magnetic field and the magnetic vectors. The combination of the magnetometer and the tilt information is for performing borehole deviation and vector magnetic surveys.
