摘要： An apparatus for reducing torque in a drill string includes a clamp assembly having a first clamp segment and a second clamp segment, the first and second clamp segments each including two circumferential ends, the two circumferential ends of the first clamp segment being configured to be connected to the two circumferential ends of the second clamp segment so as to secure the clamp assembly around an oilfield tubular and prevent the clamp assembly from rotating relative to the oilfield tubular. An outer diameter surface of each of the first and second clamp segments is generally continuous in an axial direction. The apparatus also includes an outer sleeve positioned around the clamp assembly, wherein the clamp assembly is configured to rotate with the oilfield tubular and with respect to the outer sleeve.

摘要： Systems and methods of the present disclosure relate to dampening downhole vibrations with an electroactive polymer (EAP). A downhole tool comprises a collar; an electronic control unit (ECU); a vibration sensor in communication with the ECU; a voltage source in communication with the ECU; and the EAP disposed along portions of the collar, the EAP in communication with the ECU, wherein the ECU is configured to apply voltage to the EAP based on signals received from the vibration sensor.

摘要： The swivel device attaches to a bowl or is implemented as a component of the bowl. The swivel device enables adjustment of the bowl to align the outlet with the flowline. A flange of the swivel device includes multiple fastener apertures for securing the flange to the stack. The swivel device secures the bowl to the stack while allowing rotation of the bowl. Rotation of the bowl adjusts the positioning of the outlet to align the outlet with the flowline for connecting the outlet to the flowline.

摘要： An apparatus and method for reducing torque in a drill string, in which the apparatus includes a first clamp assembly including a plurality of arcuate clamp segments that are pivotally connected together, the plurality of arcuate clamp segments being configured to be positioned around and secured to an oilfield tubular so as to be rotationally fixed to the oilfield tubular, and an outer sleeve positioned around the first clamp assembly. The outer sleeve includes at least two sleeve segments assembled together to form a generally cylindrical sleeve around the first clamp assembly, and the first clamp assembly is configured to rotate with the oilfield tubular and with respect to the outer sleeve.

摘要： A casing string torque transfer and suspension system and method for mandrel casing hangers. A running tool for a mandrel casing hanger suspending a casing string includes a pair of rotary drive rings secured around the running tool, a torque transfer ring of the pair of drive rings including a series of sloping teeth that removably couple to the mandrel casing hanger, the drive rings transferring torque to the casing string to rotate the casing string in a right-handed direction during one of running of the casing string, cementing of the casing string or a combination thereof, and the pair of rotary drive rings transferring axial loads to the casing string when the running tool is threaded to the mandrel casing hanger. Rotation of the rotary drive rings in a left-handed direction retracts the rotary drive rings as the running tool separates from the mandrel casing hanger.

摘要： Disclosed embodiments include various borehole imaging tools and methods to provide sensing surface configurations for improving the assessment of anisotropy in layered formations. In at least some embodiments, the borehole imaging tools employ a unitary conductive body to provide a wall-contacting face with grooves that define multiple elongated sensing surfaces. This wall-contacting face can be provided on an extendable sensor pad of a wireline logging tool or embedded on the outer surface of a LWD stabilizer fin. Toroids may be seated in the grooves around each elongated sensing surface for measuring the current flow through each sensing surface. The elongated sensing surfaces can be arranged in pairs as a series of rectangular-shaped grooves that are aligned perpendicularly to each other within each of the pairs to improve detection of anisotropy in thin layered formations and improve the sensitivity to dipping in anisotropic formations.

摘要： An assembly for use in subsurface drilling includes a downhole probe supported in a drill string section by centralizing features that are integral with the drill string section. A bore wall of the drill string section is fluted to provide inward contact points that support the downhole probe. The downhole probe may be supported for substantially its entire length. A vibration damping and/or electrically insulating material may optionally be provided between the downhole probe and the drill string section.

摘要： An assembly for use in subsurface drilling includes a downhole downhole probe supported by a centralizer. The centralizer comprises a tubular member that extends around the downhole probe. A wall of the centralizer is fluted to provide inward contact points that support the downhole probe and outward contact points that bear against a bore wall of a section of drill string. The downhole probe may be supported for substantially its entire length.
