  • Patent number: 9689222
    Abstract: Implementations of the present invention include a core barrel assembly including external fluid pathways extending generally axially long the outer surface of the core barrel assembly. The one or more external fluid pathways can allow for increased fluid flow around a latch mechanism. The increased fluid flow around the latch mechanism can allow the core barrel assembly to travel faster within the drill string, can allow drilling fluid to pass by the latch mechanism when engaged. Implementations of the present invention also include drilling systems including external fluid pathways, and methods of retrieving a core sample using such drilling systems.

  • Patent number: 9546524
    Abstract: Implementations described herein include a hoisting device and method for handling, coupling and recovery of tubular members such as drill string components. The hoisting device has a self-energizing gripping means configured to releasably engage a drill string component. In one aspect, the self-energizing gripping means can be operable to increase at least one of a radial biasing force and a contact friction force applied to a drill string component, causing the gripping means to increase the overall gripping force applied to the component with minimal effort exerted by a hoisting device operator.

  • Patent number: 9540883
    Abstract: Fibers for diamond-impregnated cutting tools and their associated methods for manufacture and use are described. A matrix is formed that contains fibers made from carbon, glass, ceramic, polymer, and the like. The matrix is then sintered to form a cutting portion of a drill bit. The type and concentration of the fibers can be modified to control the tensile strength and the erosion rate of the matrix to optimize the cutting performance of the tools. Additionally, the fibers may be added to the cutting section to weaken the structure and allow higher modulus binders to be used for the cutting tools at a lower cost, allowing the amount of fibers to be tailored to retain the diamonds in the cutting portion for the desired amount. As the cutting portion erodes, the fibers may also increase the lubricity at the face of the cutting portion.

  • Patent number: 9528337
    Abstract: A bushing for positioning within a core barrel assembly during an up-hole drilling operation. The bushing has a wall with an inner surface and an outer surface. The inner surface defines an inlet, an outlet, and a central bore of the bushing. The central bore surrounds a longitudinal axis of the bushing and extends between the inlet and the outlet. The outer surface has a first portion positioned proximate the inlet and a second portion positioned proximate the outlet. The first portion of the outer surface of the wall projects outwardly from the second portion of the outer surface relative to the longitudinal axis of the bushing such that the first portion of the outer surface defines opposed first and second shoulder surfaces extending substantially perpendicularly relative to the longitudinal axis. Core barrel head assemblies including such bushings are also described.

  • Patent number: 9399898
    Abstract: Drilling systems and methods for deploying a latch mechanism upon reaching a drilling position. The drilling systems and methods permit spinning of a drill string to cause a core barrel head assembly to spin through the frictional mating of a landing shoulder of the head assembly and a landing ring of an outer tube assembly. The spinning of the drill string induces a centrifugal and/or radial force that acts on the latch mechanism to overcome the frictional retention forces acting on the latch mechanism, thereby permitting deployment of the latch mechanism.

  • Patent number: 9328608
    Abstract: Implementations include a core barrel assembly having a driven latch mechanism. The driven latch mechanism can lock the core barrel assembly axially and rotationally relative to a drill string. The driven latch mechanism can include a plurality of wedge members positioned on a plurality of driving surfaces. Rotation of the drill string can cause the plurality of wedge members to wedge between an inner diameter of the drill string and the plurality of driving surfaces, thereby rotationally locking the core barrel assembly relative to the drill string. Implementations of the present invention also include drilling systems including such driven latch mechanisms, and methods of retrieving a core sample using such drilling systems.

The full face crown defines a plurality of bores that extend from a cutting face of the full face crown to the interior space. The full face crown completely circumferentially encloses the interior space of the drill bit. A wedge shaped slot is defined therein the full face crown that extends longitudinally therein a portion of the cutting face and the circumferential outer surface of the full face crown. The slot further defines an apex that is positioned beyond the center of the cutting face of the drill bit such that the longitudinal axis of the drill bit extends through the bottom surface of the slot and into an interior void area of the slot.

  • Patent number: 9267332
    Abstract: Impregnated drilling tools include elongated structures that provide enhanced properties. The drilling tools contain a diamond-impregnated cutting section that contains elongated structures made from carbon, glass, ceramic, and the like. The elongated structures can comprise tubes, fibers, or rods. In one or more implementations the elongated structures are nano-sized. The elongated structures can control the tensile strength and/or the erosion rate of the drilling tools to optimize the cutting performance of the tools. Additionally, the elongated structures may also weaken the cutting section in one or more implementations; thereby, allowing higher strength binders to be used. Such higher modulus binders can cost less and allow for tailoring of the cutting section to retain the diamonds for the desired amount of time. As the cutting section erodes, the elongated structures may also increase the lubricity at the face of the cutting section.

  • Publication number: 20160032689
    Abstract: A drill rod guard having a feed shaft assembly that supports a feed shell for receiving a drill rod. First and second shafts are respectively pivotally coupled to opposed sides of the feed shaft assembly. A plurality of guard elements are operatively coupled to the first and second shafts, and opposed guard elements are selectively engageable with one another. Upon engagement between the opposed guard elements, the guard elements cooperate with the feed shell and/or the feed shaft assembly to substantially enclose the portion of the drill rod within the feed shell to thereby prevent contact with the drill rod.
