you know drill from the university of trondheim have supported our work in developing this new technology akin to what we have supplied them with a submersible high voltage impulse generator with which to. drill an experimental well granite rock so that we can investigate the potential of this technology in the field. our device is of great interest to total engineers and of course great interest to oil companies. the potential of mechanical drilling methods that lead either with diamond heads or with load of bits has been almost fully exhausted with morton and this is why every company is now looking for a new method nor a new technology to ensure a fast boring speed especially through hard rocks like granite him in. the drilling speed is determined by the size of the fragments produced so in general the bigger the better however if the phones become too large the system may have trouble removing them from the hole by controlling the energy produced by the generator the distance between the electrodes and frequency of the electric pulses the ultimate speed can be achieved so who knows mo
