Borehole UTEM (BHUTEM)
The BHUTEM 4 system is a down-hole EM system from Lamontagne Geophysics Ltd. The main new feature of the system is its ability to do simultaneous three-component oriented down-hole UTEM measurements. The orientation of the 3-Component EM sensor is determined by the combined use of three-component magnetometer and accelerometer (temperature-compensated) sensors. The digital data are pre-processed down the hole, compressed and transmitted to the surface by means of a single fibre optical link at a rate of 100k samples simultaneously for each component. Magnetometer data, accelerometer-based tilt sensor data, temperature and system monitoring data are multiplexed with the three-component EM data.
BHUTEM 4 is the current BoreHole UTEM system.
