Conroe, Texas 77384 A rolling cone drill bit for drilling a borehole in earthen formations includes a bit body having a bit axis. In addition, the rolling cone drill bit includes a rolling cone cutter mounted on the bit body and having a cone axis of rotation. The cone cutter includes a cone body, a plurality of teeth arranged in a first inner row, and a plurality of inserts. Each insert is disposed within one tooth in the first inner row.

[BRADFORD, III, John, Francis, OMIDVAR, Navid, RAHMANI, Reza] 500 Conroe Park West DriveConroe, TX 77303 A drill bit includes a bit body and an internal plenum in the bit body. In addition, the drill bit includes a first flow passage extending from the internal plenum to a bit face. Still further, the drill bit includes a nozzle assembly secured to the bit body at a downhole end of the flow passage. The nozzle assembly has a central axis and includes an outer sleeve and an inner nozzle extending axially through the outer sleeve. The inner nozzle has a first end, a second end opposite the first end, and a radially inner surface extending axially from the first end to the second end. The radially inner surface defines a second flow passage. The inner nozzle also includes a choke disposed along the second flow passage and a side outlet extending radially from the outer surface to the inner surface. A drill bit includes a bit body and an internal plenum in the bit body. In addition, the drill bit includes a first flow passage extending from the internal plenum to a bit face. Still further, the drill bit includes a nozzle assembly secured to the bit body at a downhole end of the flow passage. The nozzle assembly has a central axis and includes an outer sleeve and an inner nozzle extending axially through the outer sleeve. The inner nozzle has a first end, a second end opposite the first end, and a radially inner surface extending axially from the first end to the second end. The radially inner surface defines a second flow passage. The inner nozzle also includes a choke disposed along the second flow passage and a side outlet extending radially from the outer surface to the inner surface.

[GONZALEZ, Israel] 7909 Parkwood Circle DriveHouston, Texas 77036 A drilling assembly comprises a bit body having a central axis (114) and a blade (202A) extending radially outward from the bit body. The blade is defined by a leading edge (218) and a trailing edge (220). A gauge surface extends from the leading edge to a surface break (216) and may be disposed at a gauge diameter (122) from the central axis (114). A recessed surface (212) extends from the surface break (216)to the trailing edge. The recessed surface may be configured to avoid contact between the trailing edge and the wellbore wall.

Dragonwood Place The Woodlands, TX 77381 A polycrystalline-diamond cutting clement (50) is disclosed for a drill bit of a downhole tool. The cutting element (50) includes a substrate (24) and a diamond table bonded to the substrate (24). The diamond table includes a diamond filler with at least one leached polycrystalline diamond segment (54) packed therein along at least one working surface thereof. The cutting element (50) may be formed by positioning the diamond table on the substrate (24) and bonding the diamond table onto the substrate (24) such that the polycrystalline diamond segment (54) is positioned along at least one working surface of the diamond table. A spark plasma sintering or double press operation may be used to bond the diamond table onto the substrate (24).

Brompton Drive Pearland, Texas 77584;602 Shadberry Drive Montgomery, Texas 77354;12920 Steepleway Boulevard, #9 Houston, Texas 77065 Apparatus including a sensor- containing body (12) is disposable within a flowbore (22) of a downhole tool. The apparatus also comprises an adjustable engagement mechanism that is coupled to the body. The engagement mechanism has a first position that allows the body to move longitudinally through the flowbore, and a second position that prevents movement of the body relative to the flowbore.

[Andrew D. MALCOLM, Roman KVASNYTSIA, Justin LOCKHART] US TX Houston A shock assembly for use with a motion tool deployable into a wellbore by a conveyance. The motion tool includes a mandrel operatively connectable to the conveyance or the motion tool, a housing operatively connectable to the motion tool or the conveyance (the housing having an opening to slidingly receive the mandrel and including a first and a second spring portion), a first spring slidably positionable in the first spring portion and having a first spring stiffness, and a second spring slidably positionable in the second spring portion having a second spring stiffness. The second spring stiffness being less than the first spring stiffness such that the first and second springs selectively engage as the housing slidingly moves about the mandrel in response to forces applied to the system to selectively restrict movement between the mandrel and the housing whereby the motion tool is vibrated.

[Aaron E. Schen, Curtis Clifford Lanning, Christopher C. Propes, Jacob D. Riddel] US TX Conroe A drill bit for drilling a borehole in an earthen formation includes a connection member having a pin end. In addition, the drill bit includes a bit body coupled to the connection member and configured to rotate relative to the connection member about a central axis of the bit. The bit body includes a bit face. Further, the drill bit includes a blade extending radially along the bit face. Still further, the drill bit includes a plurality of cutter elements mounted to a cutter-supporting surface of the blade. Moreover, the drill bit includes a depth-of-cut limiting structure slidably disposed in a bore extending axially from the cutter-supporting surface. The depth-of-cut limiting structure is configured to move axially relative to the bit body in response to rotation of the bit body relative to the connection member.
