New drilling technologies

This MIT study characterizes the requirements on new fast and ultra-deep boring technology as follows: There are more than 20 innovative drilling technology such as: laser, spallation, plasma, electron beam[1], pallets, enhanced rotary, electric spark and discharge, electric arc, water jet erosion, ultrasonic, chemical, induction, nuclear, forced flame explosive, turbine, high frequency, microwave, heating/cooling stress, electric current and several other.

Producing boreholes with wide range of diameters or drilling in water environment can be mentioned.

The research team from Slovakia has developed drilling concept based on utilization of electrical plasma.

Only a very small number of companies have embraced this method, e.g. GA Drilling, headquartered in Bratislava, Slovakia.

Other complications including on site energy and material transport from 5 to 10 km bores also require refinement to become both technically and economically feasible.
