  • Patent number: 11988072
    Abstract: Systems for drilling or tunneling include an assembly for accelerating a projectile through a first conduit into a region of geologic material, which generates debris. The debris may be reduced in size by moving the debris to a crushing device located in a second conduit using a conveying device, such as an auger. The reduced-size debris is then moved toward the surface using fluid movement. A third conduit may be used to provide and remove material from the bottom of the first conduit to control pressure at the end of the conduit to prevent ingress of material into the first conduit. 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.

  • Patent number: 11982129
    Abstract: A hybrid bit includes an earth-boring element and a percussion element. The earth-boring element and the percussion element are coaxially arranged, with the earth-boring element surrounding the percussion element. A reciprocating member of the percussion element may oscillate in a manner that enables a bottom end of the reciprocating member to repeatedly protrude from a bottom end of the earth-boring element and to be repeatedly withdrawn. A configuration of the earth-boring element may enable it to drill into and remove some materials from an earth formation, while the percussion element may enable the hybrid bit to drill into and remove difficult-to-drill materials, including abrasive materials and/or materials with high compressive forces, such as chert.

  • Patent number: 11952873
    Abstract: A washpipe free feature may include a housing defining a chamber having a bypass portion and a securing portion. The housing has first and second bores to put the bypass portion in fluid communication with an annulus of a wellbore and a central bore of a downhole tubular, respectively. Further, the washpipe free feature includes a magnet secured in the bypass portion, a ferromagnetic ball disposed within the bypass portion, and a piston disposed within the chamber. A distal end of the piston blocks the ball from contacting the magnet in a run-in position such that the ball may plug the first bore in response to fluid flow from the tubular toward the annulus.

  • Patent number: 11939857
    Abstract: Described herein are systems and techniques for monitoring for monitoring and evaluating conditions associated with a wellbore and wellbore operations that use neural operators instead of computationally intensive iterative differential equations. Such systems and techniques allow for determinations to be made as operations associated with a wellbore are performed. Instead of having to wait for computationally intensive tasks to be performed or take risks of proceeding with a wellbore operation without real-time evaluations being performed, these wellbore operations may be continued while determinations are timely made, thus improving operation of computing systems that perform evaluations and that make decisions regarding safely and efficiently performing wellbore operations such as drilling a wellbore, cementing wellbore casings in place, or injecting fluids into formations of the Earth.
