Publication number: 20230160265Abstract: A cutting element includes a substrate configured to couple to a pocket formed in a blade of a downhole drill bit and a polycrystalline diamond portion secured to the substrate. The polycrystalline diamond portion includes a cutting face, a radial sidewall, and a cutting edge formed at a transition from the radial sidewall to the axial the cutting face. The cutting face includes a plow feature disposed at a center of the cutting face. The plow feature has a face portion and a shoulder portion. The shoulder portion extends radially outward from the face portion and axially downward toward the substrate. Additionally, the cutting face includes a recessed portion extending between the cutting edge and a radially outer edge of the shoulder portion.Type: ApplicationFiled: November 19, 2021Publication date: May 25, 2023Applicant: Halliburton Energy Services, Inc.Inventors: William B.

Publication number: 20230073890Abstract: A direct high voltage flow-through water heater system transmits high voltage power to a remote ice penetrating robot, converts the power to heat in a very small space, and then uses the heat to melt the ice, providing a path ahead of the robot allowing penetration deeper into a remote ice-covered location, such ice of substantial (e.g., kilometers) thickness, such as, for example, glacial ice caps. High voltage, low current, AC power is passed through a moving conducting fluid, inducing resistive heating in the fluid with 100% efficiency. The exiting fluid is stripped of common mode voltage before exiting. Energy transfer from the electrical source to the fluid is instantaneous and occurs at 100% efficiency. In an alternative embodiment, the fluid heater system operates at standard residential/industrial mains voltages and runs from 220 VAC as other applications of the present invention include the traditional water heater industry as well.Type: ApplicationFiled: November 8, 2022Publication date: March 9, 2023Inventors: John Harman, Frederick M. Smith, William C. Stone

Patent number: 10780961Abstract: A laser-powered ice-penetrating communications payload delivery vehicle for sub-ice submarine missions enables under-ice operations to exchange information with terrestrial facilities or satellite networks with communications methods otherwise blocked by an ice cap. The vehicle comprises an electronics bay, a payload bay, optics bay, and a melt optic with laser. The system and method of establishing communication where the vehicle, tethered to a sub-ice vessel, is released. The vehicle ascends to the bottom of an ice sheet and uses a laser to melt the ice, forming a borehole through which the vehicle continues to ascend. When buoyancy no longer advances the vehicle beyond sea level, the vehicle continues to melt a conical opening through the ice until unobstructed atmosphere is reached and bi-directional communication is established.Type: GrantFiled: November 6, 2019Date of Patent: September 22, 2020Assignee: Stone Aerospace, Inc.Inventors: John Harman, William C.
