  • Patent number: 10961781
    Abstract: Anti-rotation pad assemblies are provided for restraining rotation of a non-rotating housing in geologic drilling system. The anti-rotation pad assemblies include extensible members, which extend from an internal cavity in the anti-rotation pad assemblies and are capable of engaging a wellbore wall. The extensible members may include rollers that are biased radially outwardly to engage the wellbore wall such that the anti-rotation pad assemblies may move axially within the wellbore while restraining the non-rotating housing in a particular rotational orientation. Flow ports are defined in the anti-rotation pad assemblies to encourage mud flow through the internal cavity, and thereby discourage the accumulation and solidification of drilling fluids around the extensible members. The extensible members thus remain free to move under the bias of a biasing mechanism within the internal cavity and can thus effectively maintain the rotational orientation of the non-rotating housing in the wellbore.

  • Patent number: 10450820
    Abstract: A milling apparatus for cutting a tubular in a wellbore includes a cutting element on a tool body configured to cut the tubular in a wellbore when the cutting element is activated when the tool is moving upward inside the tubular. The cutting element cuts the tubular to form cuttings that fall into an annulus between the tubular and the wellbore. An agitator below the cutting element agitates the cuttings in the annulus to aid the cuttings to move from the annulus into the wellbore below the milling apparatus.

  • Patent number: 10443316
    Abstract: A coupling adapter is insertable in at least one joint of a drill string as the drill string is extended from a drill rig. The coupling adapter includes an arrangement for receiving a data signal that is generated by an inground tool and for electromagnetically coupling the data signal onto at least a portion of the drill string that extends from the adapter to the drill rig such that at least some of the drill pipe sections cooperate as an electrical conductor for carrying the data signal to the drill rig. In another feature, a current transformer is resiliently supported to isolate the current transformer from mechanical shock and vibration that is produced by an inground operation that is performed using the drill string. In another feature, a drill string repeater is described.

  • Patent number: 10428591
    Abstract: A cutting element for an earth-boring tool includes a substrate and volume of superabrasive material positioned on the substrate. The volume of superabrasive material includes a cutting face having at least one recess extending into the volume of superabrasive material and/or at least one protrusion extending outward from the volume of superabrasive material. The volume of superabrasive material includes a first chamfer surface having a peripheral edge and a radially innermost edge. The peripheral edge of the first chamfer surface is located proximate a cutting edge of the volume of superabrasive material. A radial width of the first chamfer surface is between about 0.002 inch and about 0.045 inch. The volume of superabrasive material also includes a second chamfer surface having a peripheral edge and a radially innermost edge. The peripheral edge of the second chamfer surface is located adjacent the radially innermost edge of the first chamfer surface.

  • Patent number: 10337268
    Abstract: A device (1) for ensuring continuous circulation in well drilling includes a tubular body (2), having an axial channel (2) with a lateral opening (3) which is closed by a removable plug (5). A tubular support (9) is placed in the axial conduit and supports a shut-off member (6) which is held in position by a retainer (14). The device (1) has an adjustment ring nut (50) which exerts a pressing action between the retainer (14) and the tubular support (9) to force the tubular support (9) in an axial limit-stop position against respective positioning and centering elements (11), to allow recovery of clearances during placement of the tubular support (9) and the valve (6) supported the tubular support inside the tubular body (2).

  • Patent number: 10329851
    Abstract: A sub, downhole tool, and method for manufacturing thereof, are disclosed. The sub may include one or more flow channels, each of which may be defined in part by a longitudinal groove formed along an exterior of a collar. One or more flow channel cover may be connected to the collar. The longitudinal grooves position the flow channels further outward to provide more volume within the collar that may be used for housing one or more devices. Upper and lower blind bores are fluidly coupled to the longitudinal grooves by angled through bores to complete the flow channels. A medial bore, which may be fluidly isolated from the flow channels, may be provided to house a device, such as an instrument, detector, or circuitry.

  • Patent number: 10323465
    Abstract: A drill bit includes a bit body having cutters and a generally cylindrical rolling element secured thereon. The rolling element protrudes from the bit body to engage a geologic formation. The location and orientation of the rolling element may be selected such that an outer surface of the rolling element maintains multiple points of contact with the geologic formation to balance the operational forces acting thereon for a desired minimum depth of cut. A moment acting on the rolling element may be minimized to thereby prevent damage to the drill bit. A method for configuring the rolling element may include calculating a critical depth of cut for each point along a radial interval defined by the cylindrical body, changing a design variable, and recalculating the critical depth of cut until at least three contact points exist along the rolling element for a desired minimum depth of cut for the interval.
