Patent number: 11828108Abstract: A cutting element includes a substrate that is axially symmetric about a central axis. The substrate has a radius perpendicular to the central axis and that extends from the central axis to an outer surface of the substrate. A super-hard material is coupled to the substrate, and the central axis passes through the super-hard material. The super-hard material has an external surface defining at least one ridge protruding from a remainder of the external surface. A central point on the central axis is offset from the external surface of the super-hard material by a distance equal to the radius of the substrate. A distance measured from the external surface of the super-hard material to the central point is greatest at a position between 25° and 45° from the central axis of the substrate.Type: GrantFiled: January 11, 2017Date of Patent: November 28, 2023Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Ronald B. Crockett, Dwain Norris, Aaron Madsen, Neil Cannon, John Daniel Belnap

Patent number: 11156036Abstract: A cutting element may include a substrate including a plurality of metal carbide particles and a first metal binder having a first metal binder content; an outer layer of polycrystalline diamond material at an end of the cutting element, the polycrystalline diamond material including a plurality of interconnected diamond particles; and a plurality of interstitial regions disposed among the interconnected diamond particles, the plurality of interstitial regions containing a second metal binder having a second metal binder content. The cutting element also includes at least one transition zone between the substrate and the outer layer, the at least one transition zone including a plurality of refractory metal carbide particles and a third metal binder having a third metal binder content, the third metal binder content being less than the first metal binder content and the second metal binder content.Type: GrantFiled: January 7, 2019Date of Patent: October 26, 2021Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Madapusi K.

Patent number: 11125049Abstract: A choke valve for regulating a flow rate, a pressure or other parameters of a fluid flow may comprise a choke cage comprising a passage therethrough and a choke plug slidable within the passage. At least one conduit may pass through a wall of the choke cage and into the passage such that as the choke plug slides it may at least partially cover the conduit. A ring comprising a sintered superhard material may be secured within the conduit enhancing durability and wear resistance of the choke cage. A method for manufacturing such a choke cage may comprise subjecting grains of superhard material to high-pressure, high-temperature conditions sufficient to sinter at least some of the grains together, hollowing out the sintered superhard material to form a ring, and securing the ring within a conduit.Type: GrantFiled: January 22, 2018Date of Patent: September 21, 2021Inventors: David C. Hoyle, Neil Cannon, David S. Clark
