Abstract: A system is described for forming a debris barrier downhole in a wellbore. The system may include a mandrel, a retrievable downhole tool, and a debris ring. The mandrel may be positionable within a wellbore. The retrievable downhole tool may be positionable around the mandrel to perform tasks downhole in the wellbore. The debris ring may include an expandable material positionable around the mandrel to form a debris barrier. The debris barrier may be formed in response to exposing the expandable material to wellbore fluid.

Abstract: A system for an adjustably flexible downhole tool includes first and second connector ends each configured to connect to adjacent downhole tools and a shaft extending between the first and second connector ends. The shaft is configured to bend in response to passing through curved portions of a wellbore. The adjustably flexible downhole tool also includes an outer sleeve disposed around at least a portion of the shaft and extending from the first connector end in a direction toward the second connector end and at least one adjustable member configured to move axially, with respect to the shaft, from a first position to a second position to increase bending stiffness and/or torsional stiffness of the adjustably flexible downhole tool. The at least one adjustable member at least partially restrains bending of the shaft in the second position.

Abstract: Provided is a seal assembly, a method for sealing, and a well system. The seal assembly, in one aspect, includes a pipe having an outer tubular positioned thereabout, the outer tubular and pipe forming an enclosed seal gland. The seal assembly, according to this aspect, further includes expanded metal positioned within the enclosed seal gland, the expanded metal comprising a metal that has expanded in response to hydrolysis to assist in sealing the enclosed seal gland.

Abstract: A 3D printed barrel slip that includes a radially expandable barrel slip body that is movable from an unexpanded position to an expanded position; wherein the body has an outer surface that, when in the unexpanded position, defines a first radius; wherein the first radius is associated with a first curvature; and wherein, when in the expanded position, portion(s) of the outer surface has a second curvature that is less than the first radius. The body is an integrally formed single-component body that defines an external surface; and an internal chamber isolated from the external surface. The internal chambers affect the strength of portions of the body to control the timing of deployment of the barrel slip.

Abstract: A well tool may include a slip disposed about a mandrel and a plurality of individual wedge sections axially arranged adjacent one another between the mandrel and the slip. In at least one example, a gap is defined between adjacent wedge sections allowing a range of axial movement of one wedge section toward the other. A compliant member is disposed between the adjacent wedge sections resisting movement of the one toward the other. The compliant members may have different sizes and configurations to selectively yield at different axial loads, so that the wedge sections progressively load the slip.

Abstract: A high-expansion slip/wedge system may include at least one slip and actuatable wedge disposable about the mandrel. The actuatable wedge includes an actuator ramp configured to urge the slip radially outwardly in response to axial movement of the actuatable wedge in direct engagement with the slip ramp. A wedge extender, which may be part of a kit, is removably disposable along the mandrel intermediate the slip ramp and actuatable wedge to support increased expansion. The wedge extender may include an inwardly facing ramp engageable by the actuatable wedge and an outwardly facing ramp for engaging the slip ramp. The wedge extender provides additional engagement area for supporting and optionally increasing the amount of radial expansion.

Abstract: A shield attachment can include a brim slot and a face shield. The brim slot may be configured to receive the brim to secure the face shield attachment to the headwear. The face shield may be positioned below the brim slot, and the face shield can be configured to extend around a face of the user while the headwear is worn.

Abstract: The claimed invention provides a method for molding a decorative cup with a hard exterior shell and a molded cup with a hard exterior shell such that the ink of the decoration and the adhesive are encapsulated between the molding material and the hard exterior shell.

Abstract: Methods for hydrolyzing solid ungranulated lysophosphatidylcholine with phospholipase A2 are provided. Also disclosed are methods for making a lipid matrix of lysophosphatidylcholine, monoglyceride and fatty acid, and lipid matrices of particular structure.

Abstract: Apparatus and methods of fixating bone include repairing or remodeling a hard tissue defect with a composite bone structure. The composite bone structure includes at least two hard tissues or bones and a scaffold material fixed together by an adhesive component. The apparatus and methods include positioning the hard tissues/bones, conforming the scaffold material to at least a portion of a surface of the hard tissues/bones, contacting the adhesive component with the hard tissues/bones and the scaffold material, and changing the material state of the adhesive component to another material state at which the adhesive component fixes together the hard tissues/bones and the scaffold material, thereby forming a composite bone structure having a desired rigidity.

Abstract: An assessment is provided to identify an individual's derailers of interpersonal behavior and provide a fine-grained analysis of the identified derailers. The assessment provides a score for a number of potentially negative aspects, i.e., derailers, where each aspect is represented as a scale. A subscale structure provides additional insights about specific facets of potentially negative behavior related to each aspect. The assessment provides scores for the subscale facets to illustrate the facets most contributing to the respective potentially negative aspect of interpersonal behavior. An elevated subscale score serves as an indication that the individual is at risk for the respective facet.
