  • Patent number: 9752206
    Abstract: In the present pelletizing apparatus, the induration of iron ore concentrate pellets is achieved in a tunnel furnace heated by plasma torches, wherein the generation of CO2 by the conventional iron ore pelletizing processes is reduced by using electricity powered plasma torches instead of burning natural gas, heavy oil or pulverized coal in burners, thereby reducing considerably industrial pollution of the atmosphere.

  • Patent number: 9631433
    Abstract: The invention relates to a method for sinking or introducing cavities in rock, wherein the face of the cavity (2) is melted using electrical plasma generators. In order in such a method to produce an energy density at the face of the cavity (2), the energy density being sufficient to completely or partially evaporate the in-situ stone, the invention proposes arranging a heat shield (4) immediately over the face of the cavity (2), the heat shield (4) forming with the face of the cavity (2) a dynamic pressure space (7) in which a temperature of more than 2000° C. is established at a pressure of more than 2 bar by heating with plasma generators (8). This supply of energy is sufficient to melt the stone in-situ at the face of the cavity (2), to completely or partially gasify it and to remove it from the cavity (2).

The at-bit resistivity measurements can be for anisotropic or isotropic formations, and in the former case, can include vertical and horizontal resistivities and an orientation of the anisotropy axis. The sensors can illustratively include toroids, electrode arrays, tilted coil antennas, magnetic dipole antennas aligned with the tool axes, and magnetometers.

  • Publication number: 20150083491
    Abstract: Method and apparatus for isolating and switching lower voltage pulses from high voltage pulses in electrocrushing and electrohydraulic drills. A transformer with a high permeability core acts as a magnetic switch or saturating inductor to switch high voltage pulses to initiate an electrocrushing arc and lower voltage pulses to sustain the arc. The transformer isolates the lower voltage components from the high voltage pulses, and switches to deliver the low voltage current when the core saturates. The transformer enables impedance matching to the arc during all stages of drilling. The saturation time of the transformer core is the time delay between initiation of delivering the high voltage pulse and initiation of delivering the lower voltage current.

    Abstract: Methods, systems, and devices related to downhole wellbore operations such as drilling and completing wells in an earth formation that include a laser device. The method includes lasing a rock and detecting an optical response of the lased rock. It can be determined from the optical response whether the lased rock is responding as specified (e.g. spalling, melting, etc.) If the lased rock is not responding as specified, one or more laser parameters are adjusted to achieve the specified response. Spalling is determined by the detection of sparks, or other light that erratically changes in intensity over time, by an optical detector. The detection of steady light may indicate other types of rock removal mechanisms, such as melt or dissociation.

  • Publication number: 20130112478
    Abstract: Equipment for laser-drilling having an optical component or feed module with a set of lasers, the active optical fiber, in the form of hollow coil, the excitation of the laser active medium made through the coupling of the light emitted by laser diodes inside the active fiber, and a mechanical component that is an optic drill bit with a hollow rigid body and an end of any geometry, the drill bit having leaky orifices for the optical fibers connection or bundle of optical fibers with drill bit walls and orifices to allow the drilling and cooling fluids are released in the surface to be drilled, the optical fibers being provided from the feed module. The feed module generates high intensity light generation that through optical fibers is guided to the optic drill bit. The feed module and the optic drill bit are coupled to a drill string.

  • Publication number: 20130032397
    Abstract: In at least some embodiments, a pulsed-electric drilling system includes a bit that extends a borehole by detaching formation material with pulses of electric current from one or more electrodes, and a drillstring that defines at least one path for a fluid flow to the bit to flush detached formation material from the borehole. The system modulates the fluid flow across the one or more electrodes. This modulation may enhance the performance of the pulsed-electric drilling process.

  • Publication number: 20130032399
    Abstract: Pulsed-electric drilling systems can be augmented with a steering mechanism that shifts at least a portion of a bit relative to a borehole centerline. Illustrative mechanisms include ball-and-socket joints, pivot-and-hinge joints, rotary steerable systems, and bent subs. As the bit detaches formation material using electric pulses, the detached material being flushed away by a flow of drilling fluid, the shifting of the bit from the centerline causes the borehole to turn in the direction of the bit.
