摘要： A system and method of detecting a vibration of a drill string in a borehole. The drill string is conveyed into the borehole, the drill string including an electrical machine, the electrical machine including a stator and a movable element, the movable element movable relative to the stator, the drill string is rotated in the borehole. A control circuit determines first amplitude of the vibration of the drill string by measuring a signal indicative of a movement of the movable element in the electrical machine due to rotation of the drill string and controls a downhole operation of the drill string based on the detected first amplitude of the vibration.

摘要： A cutting table for a cutting element, including: a diamond phase; a tungsten carbide phase; a cobalt-tungsten metallic phase; and an intermetallic phase comprising Co3WCx, where 0≤x≤1. Also disclosed is a method of manufacturing a cutting element, the method including: sintering diamond and tungsten carbide particles in the presence of Co and W to about 1520° C. or greater under pressure of about 57 kbar or greater to form a hard metal-diamond composite compact and solubilize carbon and tungsten within the compact; cooling the cutting element at about 1° C./sec or greater; and subsequent to cooling the cutting element, heat-treating the cutting element to precipitate carbon and tungsten in the compact as an intermetallic phase.

摘要： A method includes: injecting a first spacer fluid into a wellbore that comprises a drilling fluid, the first spacer fluid containing barium sulfate and a first spacer fluid carrier, and injecting into the wellbore a second spacer fluid containing a chelating agent and a second spacer fluid carrier. A spacer fluid system includes: a first spacer fluid containing barium sulfate and a first spacer fluid carrier; and a second spacer fluid containing about 10% to about 30 wt % of a chelating agent based on a total weight of the second spacer fluid, and a second spacer fluid carrier.

摘要： A method for managing carbon containing gases, including conveying the carbon containing gas to a reactor vessel, conveying propylene oxide to the vessel, reacting the carbon containing gas with the propylene oxide to create propylene carbonate (PC), applying the propylene carbonate to a cuttings stream from a borehole in a subsurface drilling operation and dissolving residual oil from cuttings of the stream into the propylene carbonate. A system for managing carbon containing gas emissions from a borehole drilling operation, including a carbon containing gas emitter, a reactor vessel fluidly connected to the emitter, a propylene oxide supply fluidly connected to the reactor vessel and an applier connected to the reactor vessel, the applier configured to apply propylene carbonate (PC) created in the reactor vessel to a cuttings stream.

摘要： A seal assembly including a seal subassembly disposed upon a seal subassembly configured to hold pressure, a first load member having a first side disposed adjacent a first side of the seal subassembly, the first load member configured to engage the seal subassembly such that the first load member independently has a limited axial movement capability in both longitudinal directions along the seal assembly, and a first energizer adjacent a second side of the first load member, the first load member isolating the first energizer from mechanical loading in a direction opposite a direction of bias of the first energizer. A downhole tool including a housing, and an actuator disposed in the housing, the actuator including a seal assembly. A wellbore system including a borehole in a subsurface formation, a string disposed in the borehole, a downhole tool disposed within or as part of the string and including the seal.

摘要： A seal arrangement includes a seal assembly and a seal subassembly in operable contact with the seal assembly. The seal subassembly is configured to impart energy to the seal assembly to promote sealing of the seal assembly with a mating surface. A non-sealing feature of the seal subassembly depends from the seal subassembly and is interactive with a load shoulder of a structure adjacent the seal subassembly. The seal arrangement redirects a mechanical load path through the seal subassembly to the non-sealing feature, during use. A method of protecting a seal subassembly from reverse loading is by redirecting a load path through a seal subassembly to a non-sealing feature, while also permitting pressure energizing of the seal assembly by the seal subassembly in a sealing direction. A downhole system includes a borehole in a formation, a string in the borehole, and a seal.

摘要： In at least one embodiment, a compression plate to be used with a slip hanger or a packoff in oilfield equipment is disclosed. The compression plate includes one or more grooves or slots extending circumferentially with respect to an axis of the slip hanger or the packoff. The compression plate is to be associated with an annulus seal gland of the slip hanger or the packoff and is to enable a gland volume of the annulus seal gland to change with temperature applied to the slip hanger or the packoff.

A method for creating a sealed structure including mechanically connecting the first and second members to one another, causing a deformation at a contact area between the compliance portion and the second member, and creating a seal at the deformation. A borehole system including a borehole in a subsurface formation, a string in the borehole, and a seal disposed within or as a part of the string.
