摘要： A system that can include a centralizer configured to be radially positioned between a tool and an internal bore of a tubular, wherein the centralizer is configured to engage the internal bore and the tool via a plurality of biasing devices circumferentially spaced away from each other about a center axis of the centralizer. A method can include installing a biasing device in a plurality of protrusions that extend radially outward, extending a portion of each biasing device past an outer radial surface of a respective protrusion to engage a tubular, and extending a portion of each biasing device past an inner radial surface of a central bore of the centralizer to engage a tool, where the first portion and the second portion are configured to substantially align a center axis of the tool with a center axis of the tubular when the tool is installed in the tubular.

摘要： A tubular is prepared for downhole use to include integrated centralizer feature disposed thereon. Blade elements are disposed about a surface of the tubular. An interconnection, such as a band, connected between the blade elements can be used to wrap them circumferentially about the tubular. The blade elements are then affixed to the surface of the tubular to produce the integrated centralizer features by coating a spray welding material over at least a portion of the plurality of blade elements and over at least an adjacent portion of the surface of the tubular. The blade elements can be hollow vanes or fins so they are collapsible when a restriction is encountered downhole to avoid a stuck pipe situation.

摘要： An apparatus comprises an electrode assembly positioned at a bottom end of a pulse power drill string to be positioned in a borehole formed in a subsurface formation. The electrode assembly comprises multiple electrodes, wherein at least a subset of the multiple electrodes is to periodically emit a pulse of an electrical discharge into the subsurface formation to drill the borehole. The electrode assembly comprises a controller configured to alter a direction of drilling of the borehole based on selection of the subset from the multiple electrodes, wherein an effective attribute of at least one electrode of the multiple electrodes is different than the effective attribute of other electrodes of the multiple electrodes, wherein the effective attribute comprises at least one of a shape and a size.

摘要： The present invention relates to a wireline cased-hole roller (WCRO) for deployment during a logging operation that reduces slickline or e-line cable contact and drag in the cased hole section of a wellbore. Arrays of WCROs, clamped on the slickline or e-line, reduce logging tensions and improve force transmission from surface down to the tool cable head by significantly reducing the cased-hole cable drag. They also permit the use of lower grade cables or winches in certain environments due to lower logging tensions. Another benefit is the mitigation of cased hole cable wear zones since the cable is suspended above the casing, liner or tubing. In high-angle or horizontal wells, arrays of WCROs aid conveyance and improve tractor performance by reducing the cable drag force which has to be overcome to reach the target zone.

摘要： A packer arrangement for a sealed passage of a drillstring therethrough. The drillstring has geometric differences between passing drill pipes and joint couplings. The packer arrangement includes a packer holder which forms a housing with an axially through-going center passage which has a flexible packer sleeve arranged in a portion thereof, an external annulus which encloses the packer holder, an internal annulus, and two actuators which apply an axial tensile force to the flexible packer sleeve. The flexible packer sleeve has a center portion and two end terminations which are axially displaceable in the packer holder. The internal annulus is delimited by the center portion of the flexible packer sleeve and by the packer holder. The internal annulus is in a fluid communication with the external annulus. Each of the two end terminations is coupled to one of the two actuators, respectively.

摘要： A method includes directionally drilling, with a pulse power drill string, of a borehole into a subsurface formation using pulse power. The directionally drilling comprises generating, by an electrical source, an electrical energy and storing, by a primary capacitor, the electrical energy. The method includes periodically discharging the electrical energy from the primary capacitor to be received by a switching device having a number of outputs, wherein each output of the number of outputs is electrically coupled to an electrode of a number of electrodes positioned on an electrode assembly; and unevenly distributing, by the switching device, the electrical energy across the number of electrodes based on selecting a subset of the number of electrodes to receive the electrical energy to alter a direction of the drilling of the borehole based on emitting of the electrical energy by the selected subset of the number of electrodes into the subsurface formation.

摘要： A directional drilling assembly includes a downhole piston and an uphole piston. A downhole piston diameter of the downhole piston is smaller than an uphole piston diameter of the uphole piston diameter. This may allow the downhole piston and/or the uphole piston to be located closer to the bit, thereby improving the maximum DLS of the system.
