  • Method for real time location of deep boreholes while drilling
    Patent number: 5680906
    Abstract: The present invention is concerned with a system for the real time location of deep boreholes while drilling. The system includes a plurality of sensors sensitive to seismic vibrations disposed in an area where a borehole is to he drilled, the sensors being adapted to selectively pick up the vibrations emitted by the drilling bit as it progresses through the rock. The data picked up by the sensors is then processed and the results are displayed in real time, thus allowing the operator to know precisely the location of the drill bit as the hole is being drilled.
