  • Patent number: 10400598
    Abstract: Invention relates to the mining industry and may be used for magmatic lava extraction and lifting to the surface for further processing. The disclosed method comprises using a carrier pipe for lava lifting and a smaller diameter pipe for injection of an incombustible gas, wherein the pipes are connected via a disperser. The carrier pipe and the disperser have a plurality of holes of various diameters to ensure efficient lava saturation by gas. The dispenser is preferably designed as cowl concentrically wrapped around carrier pipe. The effect of lava lifting through the carrier pipe is achieved via repetitive lowering and lifting motions of the carrier pipe with simultaneous lava saturation with the gas inside the carrier pipe, which lowers the lava viscosity. After stabilization of the flow velocity of the gas-saturated lava from the carrier pipe, the lava lifting process is changed to lava collection conditions.

  • Patent number: 10378321
    Abstract: A plunger for oil and gas wells includes a shaft and a sleeve carried by the shaft. The sleeve defines a passageway located between a surface of the sleeve and a portion of the shaft, and the sleeve is longitudinally translatable relative to the shaft from a first configuration to a second configuration and vice versa. In the first configuration the plunger inhibits fluid flow through the passageway, and in the second configuration the plunger permits fluid flow through the passageway. The plunger further includes a force dissipating element interposed between the shaft and the sleeve. The force dissipating element at least partially dissipates forces caused by at least one of (1) the sleeve stopping relative to the shaft after translating from the first configuration to the second configuration; and (2) the sleeve stopping relative to the shaft after translating from the second configuration to the first configuration.

  • Patent number: 10364657
    Abstract: A composite drill gun for use in a wellbore environment can include a detonation housing containing a detonation source, a composite carrier containing one or more encapsulated charges, and a detonation train connecting the detonation source to the encapsulated charges. The detonation source and each individual encapsulated charge are all sealed with respect to the wellbore environment, and thus the carrier need not be sealed with respect to the wellbore environment. The carrier can be made out of composite materials without worry of leaks into the interior of the carrier, as the detonation source and encapsulated charges are all sealed with respect to the wellbore environment. The composite carrier can be easily drilled out of the wellbore after detonation.
