摘要： A system for generating pressure pulses in drilling fluid includes a concentric drive power section. The power section includes a stator and a rotor rotatably disposed in the stator. The rotor is coaxially aligned with the stator. The system also includes a valve. The valve includes a first valve member coupled to the stator and a second valve member coupled to the rotor. The second valve member is configured to rotate with the rotor relative to the first valve member and the stator. The rotation of the second valve member relative to the first valve member is configured to generate pressure pulses in drilling fluid flowing through the concentric drive power section.

摘要： A cutting element for a drill bit includes a body having a face at an end thereof. The face includes a ramp, a first side region, a second side region, and a ridge thereon. The ramp has a curved edge along a periphery of the face, a first side, and a second side. The first side and the second side extend from opposite ends of the curved edge and converge at a location along the face. The ridge extends along the face from a chamfer along a peripheral edge of the face to the location. The ridge is positioned between the first side region and the second side region. The first side region extends between the periphery, the ridge, and the first side. The second side region extends between the periphery, the ridge, and the second side. The ramp extends from the first side region to the second side region.

摘要： A downhole activation assembly for activating a downhole component of a downhole tool positionable in a wellbore penetrating a subterranean formation. The activation assembly includes a housing operatively connectable to the downhole tool, a spring-loaded sleeve, and a ball catcher. The sleeve slidably positionable in the housing, and having a flow channel therethrough and an outer surface defining a chamber between the sleeve and the housing. The sleeve having inlets therethrough about a sleeve end thereof to permit fluid from the flow channel to pass therethrough. The ball catcher slidably positionable in the housing, and having a catcher end engageable with the sleeve end to selectively divert the fluid thereabout and a ball seat therein to receivingly engage a ball passing through the sleeve whereby the ball catcher selectively moves the downhole component between activation positions.

摘要： A drill bit assembly that includes a shank including a shank axis, first and second ends, a drill bit seat at the second end and a central flow bore extending axially from the first end. Additionally, the assembly includes a sleeve disposed about and translatable axially relative to the shank and a drill bit rotatably coupled to the sleeve. The drill bit includes a first bit face having a first cutting structure configured to engage an earthen formation, and a second bit face having a second cutting structure configured to engage the earthen formation. The drill bit is configured to rotate about the about the shank axis in a cutting direction, and to rotate about an axis of rotation being orthogonal to the shank axis to selectively expose the first or second cutting surface to the earthen formation. The seat is configured to receive the first or second bit face.
