Patent number: 11719047Abstract: Geologic material in a borehole is weakened by accelerating a projectile into contact with the material. A drill bit is then used to bore through the weakened material. To accelerate the projectile, an endcap is placed in a conduit using a source of gas. The endcap isolates the conduit from the external environment. A projectile is then positioned in the conduit above the endcap. Movable members within the conduit are operated in sequence to enable single endcaps and projectiles to be moved into the conduit. Gas from the conduit is evacuated into an annulus between the conduit and a surrounding conduit, and a propellant material is provided into the conduit. The propellant material applies a force to the projectile to accelerate the projectile into contact with the geologic material. A fluid is circulated down a second annulus outside of the surrounding conduit to contact the drill bit and remove debris.Type: GrantFiled: March 23, 2022Date of Patent: August 8, 2023Assignee: HYPERSCIENCES, INC.Inventors: Mark C. Russell, Lance D. Underwood, Leon Vanstone, Parker Bailey, Desiree Elizabeth Bernhard, Tristen Cutshall, Kaito J. Durkee, Kordell Newberg, Aaron J. Abeyta

Patent number: 11634966Abstract: The present invention provides a cartridge (1) for a chemical heater used in down-hole operations. The cartridge (1) comprises a quantity of a chemical reaction heat source (2) wrapped in a temporary coating (3) that is capable of maintaining the shape of the cartridge (1) prior to use but which is consumed during the burn of the heater. The present invention also provides a eutectic/bismuth based alloy well plugging/sealing tool (5). The tool (5) having a tubular heater body (6) with an internal cavity (8) capable of receiving a chemical heat source and a quantity of eutectic/bismuth based alloy (7) provided in thermal communication with the heater body (6) around an outer surface of the heater body (6). The tool has a sleeve (10) provided around an outer surface of the alloy (7), which insulates and/or mechanically protects the alloy (7) down-hole. In this way the sleeve (10) enables the diameter of tool (5) to be reduced whilst maintaining its functionality.Type: GrantFiled: May 24, 2017Date of Patent: April 25, 2023Assignee: BiSN Tec.

Patent number: 11624235Abstract: Systems for drilling or tunneling include an assembly for accelerating a projectile into a region of geologic material. An interaction between the projectile and the geologic material extends a borehole and forms debris. The debris may be reduced in size by moving the debris to a crushing device. The reduced-size debris is then moved toward the surface using fluid movement. Water jets or other types of devices may be used to cut or deform a perimeter of a region of geologic material before the projectile is accelerated to control the shape of the borehole and the manner in which debris is broken from the geologic material.Type: GrantFiled: August 16, 2021Date of Patent: April 11, 2023Assignee: HYPERSCIENCES, INC.Inventors: Mark C.
