WebThe rock is destroyed with essentially no contact, which drastically reduces the wear on the drilling tools and increases the service life of all drilling components, which is an absolutely essential factor of any drilling process. The process is especially suitable for hard, crystalline rocks, such as the rocks found in geothermal reservoirs. WebPulsed power can be used to generate powerful shockwaves in a liquid environment. These shockwaves can be used to break apart rocks, either to clear blockages in oil wells or as part of a crushing process for use in mineral recovery. They can also be used to push metals at high speeds for electro-hydraulic forming applications.
