Abstract: Embodiments described herein provide an expanding and collapsing apparatus and methods of use. The apparatus includes a plurality of elements assembled together to form a ring structure about a longitudinal axis. The ring structure is operable to be moved between an expanded condition and a collapsed condition by movement of the plurality of elements. At least one set of structural elements are operable to move between the expanded condition and the collapsed condition by movement of a first end in an axial direction, and by movement of a second end in a radial dimension. In certain embodiments, the plurality of elements includes at least one set of structural elements extending longitudinally on the apparatus and operable to slide with respect to one another. Applications of the embodiments described herein include oilfield devices, including anti-extrusion rings, plugs, packers, locks, patching tools, connection systems, and variable diameter tools run in a wellbore.

Abstract: A seal system includes a first annular component having a radially-outer surface with a first threaded portion and a first sealing portion, wherein the first sealing portion has a first angled surface that is oriented at a first angle relative to a vertical axis. The seal system also includes a second annular component having a radially-inner surface with a second threaded portion and a second sealing portion, wherein the second sealing portion has a second angled surface that is oriented at a second angle relative to the vertical axis, and the second angle is different from the first angle. The first annular component and the second annular component are configured to threadably couple to one another via the first threaded portion and the second threaded portion and to form a metal-to-metal seal against one another via the first angled surface and the second angled surface.

Abstract: A technique facilitates patching of a tubing (42), e.g. casing (36), in a downhole environment (32). The technique employs a patching system comprising a plurality of expansion rings (48). The expansion rings (48) are moved downhole to a patch zone (38) along the tubing (34). Once in a desired position at the patch zone, the expansion rings (48) are expanded into engagement with an inner surface of the tubing. For example, the expansion rings may comprise seal elements (52) and/or anchor elements which are expanded into engagement with the inside surface. The patching system further comprises a patch (68) which may have a tubular shape. The patch is radially expanded in a manner which maintains a sealing engagement with the plurality of expansion rings (48) to create a sealed patch across a desired region in the patch zone.

Abstract: The present disclosure relates to integrated systems, methods and apparatuses for assisting individuals in managing acute life-threatening conditions. A system in accordance with the current disclosure may comprise an electronic circuit configured to be attached to a container of a medication and one or more devices in communication with the electronic circuit in a private network. In an aspect, the one or more devices may work in concert to determine the safety level of an individual based on predetermined usage settings. In some aspects, the system may be configured to determine whether a medication would expire before its manufactured expiry date. In another aspect, the system may assist an individual in locating a medication. In a further aspect, the system may determine whether an individual is having an anaphylactic reaction. In some aspects, the system may detect a known allergen and alert the individual.

Abstract: Described are processes for the manufacture of compounds containing a (S)-4,5-dihydro-1H-pyrazole ring. These processes include a chiral resolution step of an intermediate using selected chiral resolving agents. For example, the chiral resolving agents may be selected from (?)-quinine, (R)-phenethylamine, (S)-phenethylamine, (S)-1-naphthylethy lamine, (R)-(?)-2-amino-3-methyl-1-butanol, (?)-cinchonidine, (?)-spartein, (R)-1-naphthylethy lamine, D-arginine, L-lysine, (S)-(+)-2-pyrrolidinemethanol and(1R,2S)-(+)-cis-1-amino-2-indanol.

Abstract: Embodiments described herein provide a downhole tool (e.g., a retrievable bridge plug) that includes a sealing device and a load retention/equalization mechanism. The sealing device includes an elastomer seal component and an expansion device configured to radially expand outwardly to compress the elastomer seal component against a wellbore casing within which the downhole tool is located. The sealing device further includes lower and upper support barriers configured to radially expand outwardly against the wellbore. The sealing device also includes a seal energizing spring configured to maintain an initial setting force of the elastomer seal component against the wellbore casing.
