摘要： An electronics module or "puck" is positioned in a recess formed in the outer surface of a downhole tool. The puck body includes a flange segment having a first outer diameter, and an adjacent seal-engaging segment having an outer diameter that is less than the outer diameter of the flange segment. An annular seal is disposed about the seal-engaging segment and seals between the puck and the perimeter wall of the recess. A cover ring is disposed over an intermediate segment of the puck body, capturing the seal between the cover and the flange segment. A retainer ring is employed to selectively engage and disengage the perimeter wall of the recess, retaining the puck, seal and covering ring in the recess. A method for installation and removal of the puck is disclosed.

摘要： Embodiments relate generally to preventing wear to a nominal thickness of a wall of a drill pipe during a downhole operation. A drill pipe may include a first tool joint; a second tool joint; and a tubular section between the first tool joint and the second tool joint, wherein the tubular section comprises a wall with an overall thickness comprising a nominal thickness and a secondary thickness, wherein the secondary thickness is outer to the nominal thickness and is configured to abrade against a wall of the wellbore, thereby reducing the secondary thickness and maintaining the nominal thickness, wherein an ID of each tool joint is less than an ID of the tubular section to accommodate for threaded connectors.

摘要： A method of manufacturing a bifunctional electrocatalyst for overall water splitting comprising oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) by growing electrocatalyst comprising primarily metallic phosphides on a three-dimensional substrate by: immersing the substrate in an iron nitrate solution to form a once disposed substrate; subjecting the once disposed substrate to thermal phosphidation with phosphorus powder under inert gas to grow metal phosphides thereupon and form a once subjected substrate; cooling the once subjected substrate to form a cooled, once subjected substrate; immersing the cooled, once subjected substrate in an iron nitrate solution to form a twice disposed substrate; and subjecting the twice disposed substrate to thermal phosphidation with phosphorus powder under inert gas to provide an electrode comprising the bifunctional electrocatalyst on the three-dimensional substrate.

The RSA (125) includes a sleeve (130) configured to rotate relative to the housing (110) and a second bore coaxially aligned with the central bore of the housing, A piston port (152) in the sleeve extends to the second bore, and a piston (200) disposed in the piston port (152) is configured to reciprocate between a first position and a second position in response to a change in pressure of fluid within the second bore. The piston port (152) and the piston (200) are disposed at a location in the rotating sleeve that passes the sensor periodically when the rotating sleeve rotates; the sensor (120) configured to detect the piston (200) when it rotates past the sensor (120) and is in its second position.

The tab (264) is received in a recess (152) in the first tubular member (135) and has a beveled surface (266). A key (270) is configured to be disposed in the first recess (152), and has a beveled surface (271) that engages the beveled surface (266) of the tab (264). A through-bore (276) in the key (270) is aligned with a fastener-receiving bore (124) in the first tubular member (135) and a fastener (232) is disposed in the aligned bores (276, 124). A second castellated annular surface (212) coupled to the second tubular member (105) has teeth (214) meshing with the teeth (244) of the first castellated annual surface (242).

摘要： A tubular member (100) includes a tube body (109), a tube end (112,113), an exterior surface (140), an interior surface (142), a nominal wall thickness, a longitudinal axis (111), a welded seam (110), and a patch of material (205). The welded seam forms an arcuate portion of the interior surface, and the patch covers a portion of the interior surface that includes a portion of the welded seam, extending from the tube end to an axially spaced first location. The resulting interior surface from the tube end to the axially spaced first location has a uniform inside diameter.

摘要： A lifting mast assembly includes telescoping load bearing arms pivotably coupled to a support base and configured to pivot in unison. Each telescoping arm includes a first arm section and an aligned second arm section. The first arm sections are configured to telescope in unison with one another. Likewise, the second arm sections are configured to telescope in unison with one another. Each first arm section may telescope independently of the second arm section with which it is coaxially aligned. A first support member is coupled to each of the first arm sections, and a second support member is coupled to each of the second arm sections. Different loads can be supported on the first and second support members simultaneously.

摘要： Systems and methods discussed herein are related to a coating for a diamond table for a cutting element that may be used in downhole tooling. The coating is employed to fill a plurality of voids left by the manufacturing process that compromise the integrity of the cutting element and the associated downhole tooling. The coating may comprise diamond nanoparticles in a metal matrix and may be used with or without a binder layer applied directly to the diamond table, the coating may alternatively be a pure diamond film coating, and may be employed to fill voids left by the manufacturing process.
