Abstract: A method of designing a drill bit is disclosed. The method includes determining a location of a bit coordinate system in a wellbore coordinate system and generating a bit profile based on an angular coordinate around a wellbore axis of a wellbore and the location of the bit coordinate system. The bit profile is based on a cutting edge of a first cutting element on an exterior portion of a first blade. The method also includes determining a cutting layer volume based on the bit profile and identifying a weak zone based on the cutting layer volume being less than a predefined minimum cutting layer volume. The method includes determining a location for a second cutting element on the exterior portion of a second blade based on the weak zone.

Abstract: A method includes positioning at least one guide projection on a substrate of a metal part such that the at least one guide projection extends outwardly from an outer surface of the substrate to an exposed length. Hardfacing is then applied to the substrate of the metal part at or near a location of the at least one guide projection. The exposed length of the at least one guide projection is then referenced in determining when to cease application of the hardfacing.

Abstract: There is disclosed herein a method of designing a mold, the mold being at least part of a unitary body to be formed from a plurality of layers by 3D printing, the method including defining an inner surface of the mold corresponding to at least part of an outer surface of an object to be molded in the mold; selecting a first material from which at least part of the mold is to be printed; and selecting a second material from which at least another part of the mold is to be printed, the second material having a higher thermal and/or electrical conductivity than the first material, wherein at least one of the layers from which the mold is to be formed by 3D printing includes areas to be printed from each of the first and second materials.

Abstract: In some embodiments, a magnetometer mounting apparatus and system may reduce noise and magnetic flux interference by mounting the magnetometer inside a cavity in a collar that fits around a tool insert. The cavity may be sealed with a hatch cover/outsert. Another embodiment mounts a plurality of magnetometers around the periphery of a mounting ring that is coupled to the insert. Yet another embodiment mounts the magnetometers in a gap sub in the BHA. Still another embodiment longitudinally mounts the magnetometers on the insert such that a diagonal distance between two magnetometers is the greatest possible on the insert.

Abstract: A drill bit for directional drilling includes a main body and a wear component. The main body is unitary and formed of a first material. The main body includes opposed outer surfaces and a periphery extending between the opposed surfaces. The wear component is unitary and is formed of a second material that is harder than the first material. The wear component comprises a retention portion and a wear portion. The retention portion is positioned within the first material of the main body. The retention portion includes opposed retention surfaces that, moving in a direction inward from the periphery of the main body, taper apart from each other toward the opposed outer surfaces of the main body. The wear portion extends outward from the retention portion relative to the periphery of the main body. The wear portion is substantially planar and is configured to form an outer wear edge.

Abstract: A downhole tool includes a fastening assembly securing one component to another component. The fastening assembly may include a threaded fastener located in an aperture of one component and a locking mechanism located in a cavity proximate the aperture. The threaded fastener may include a flange including mutually spaced holes located circumferentially within an outer periphery of the flange. The locking mechanism may include a spring and a dowel member. The locking mechanism may be positioned within a hole of the flange and may be configured to retain the threaded fastener in a fixed position relative to one component. Methods include using a depressor ring including teeth corresponding to the holes of the flange to depress the locking mechanism into the cavity while tightening the threaded fastener.

Abstract: A wellbore tool may be formed, at least in part, by a fiber-reinforced hard composite portion that comprises a binder, matrix particles, and reinforcing fibers. The reinforcing fibers may have an aspect ratio ranging from equal to a critical aspect ratio (Ac) to 15 times greater than the Ac. In the formula, Ac=σf/(2τc), σf is an ultimate tensile strength of the reinforcing fibers, and τc is an interfacial shear bond strength between the reinforcing fiber and the binder or a yield stress of the binder, whichever is lower.

Abstract: Partially formed earth-boring rotary drill bits comprise a first less than fully sintered particle-matrix component having at least one recess, and at least a second less than fully sintered particle-matrix component disposed at least partially within the at least one recess. Each less than fully sintered particle-matrix component comprises a green or brown structure including compacted hard particles, particles comprising a metal alloy matrix material, and an organic binder material. The at least a second less than fully sintered particle-matrix component is configured to shrink at a slower rate than the first less than fully sintered particle-matrix component due to removal of organic binder material from the less than fully sintered particle-matrix components in a sintering process to be used to sinterbond the first less than fully sintered particle-matrix component to the at least a second less than fully sintered particle-matrix component. Earth-boring rotary drill bits comprise such components sinterbonded together.
