Publication number: 20100000790Abstract: The present invention provides for pulsed power breaking and drilling apparatuses and methods. The present invention comprises two pulsed power systems coordinated to fire one right after the other. The first pulsed power system, comprising a spiker, may create a high voltage pulse that breaks down the insulative properties of the substrate and may create an arc channel in the substrate. It is designed for high voltage but low energy, at high impedance. The second pulsed power system, comprising a sustainer, is designed to provide high current into the arc, but at low voltage, thus better matching the impedance of the arc and achieving much more efficient energy transfer.Type: ApplicationFiled: July 14, 2009Publication date: January 7, 2010Applicant: Tetra CorporationInventor: William M.
