    Abstract: The present application pertains to a compression packing seal including a braided dual-sided jacket, methods for producing and using such a seal, and apparatuses suitable for producing such a seal. The compression packing seal is made up of a core (132) and a jacket (134) braided round the core. The jacket may include two or more different materials (140, 150) that are braided together in such a way that, in cross-section, the jacket has an asymmetrical configuration relative to a first axis that is substantially perpendicular to the longitudinal axis and is substantially perpendicular to a side of the jacket. Accordingly, when viewed in a cross-sectional plane, the jacket may expose substantially only a first material along a first side, and substantially only a second material along a second side.

    Abstract: Subsea wells have a variety of proprietary well head configurations that require sophisticated locking and sealing profiles that allow the well bore to be sealed off and the production of hydrocarbons to be safely controlled. A universal tubing hanger and lockdown assembly uses a sealing apparatus to annularly seal the well bore. When compressed, a multi-piece stacked sealing system employs rigid and elastic members to seal the well bore annulus in both the top-down and bottom-up directions. Top-down pressure containment is needed for appropriate well system testing and bottom-up pressure containment is necessary to control the internal pressure of the well.

    Abstract: A labyrinth seal assembly is provided for forming a seal between a shaft and housing. The seal assembly includes a stationary element configured to be coupled to the housing and having an annular shape defining a space through which the shaft extends; a rotary element disposed within the space and coupled to the shaft so as to rotate therewith, the rotary element having an outer surface that extends in an axial direction and having a groove formed therein, the rotary element being disposed between the stationary element and the shaft; and a valve element mounted within the groove and disposed between the stationary element and the rotary element when assembled to form the seal. The valve element is formed from an elastomeric material.

    Abstract: A split mechanical composite seal assembly for providing a seal between a rotating shaft and a static surface. The split mechanical composite seal assembly includes first and second axially adjacent annular seal elements. The first and second seal elements each include a sealing edge contacting the shaft to provide a respective seal between the first and second seal element and the shaft. A static housing receives the first and second seal elements and engages the static surface to provide a static stationary seal, while concomitantly providing a flex region that engages the seal elements to form a dynamic seal therewith. A holder assembly receives one seal element and may include a double-angled lead-in to facilitate installation of the seal element. The holder assembly may include a detent groove for receiving and retaining an O-ring disposed about the seal element. The static housing may comprise two mating segments having overlapping surfaces.

    Abstract: A loading mechanism (30) for a fluid seal (10) that allows an installer to change or adjust the axial bias applied to a stacked set of sealing elements (12). The loading mechanism includes a bolt-like adjusting element (66) that has a foot portion (80) attached to one end (74) and a rail element (32) that is threadingly coupled at an opposite end (72). By rotating the adjusting element, the rail element can travel axially along the adjusting element. The axial displacement of the rail element allows the installer to select the amount of axial force or bias applied by the loading mechanism to the sealing elements.
