    Abstract: A segmented backup ring including a plurality of individual segments each having curved surfaces that define an arcuate portion of the ring, each segment including a body section having the arcuate profile and defining a receptacle therein having a circumferential dimension, a projection section having a head portion and a neck portion and extending from the body section in a circumferential direction of the ring, the projection section being receivable and retainable in the receptacle of an adjacent segment body section, and the head portion having a dimension in line with the circumferential direction of the ring that is shorter than the circumferential dimension of the receptacle.

    Abstract: A downhole electrohydraulic movement arrangement including a spark gap device positioned and configured to move a separate component, and an energy source electrically connected to the spark gap device. A method for moving a component in a downhole environment including disposing an electrohydraulic arrangement having a spark gap device and an energy source electrically connected to the spark gap device operably proximate a component, actuating the spark gap device, generating a pressure wave with the spark gap device, and moving the component with the pressure wave. A downhole system including a borehole, a component moved within the borehole by an electrohydraulic arrangement.

    Abstract: A backup including a gage ring having frustoconical surface and a groove in the frustoconical surface, a segment having a nose engaged with the groove, the segment having an overlap finger and a finger receptor, a wedge ring in contact with the segment, and a retainer member disposed to retain the segment. The downhole tool further comprising a second backup also adjacent the element and spaced from the first backup by the element. A borehole system including a borehole in a subsurface formation, a string dispose within the borehole, a backup disposed within or as a part of the string. A borehole system including a borehole in a subsurface formation, a string dispose within the borehole, a tool disposed within or as a part of the string.

    Abstract: An apparatus for generating power includes a fluid chamber configured to receive borehole fluid, one or more conductive coils surrounding the fluid chamber, a reciprocating magnetic shuttle disposed in the fluid chamber and dividing the fluid chamber into a first volume and a second volume, a first conduit connected to the first volume, and a second conduit connected to the second volume, the first conduit and the second conduit extending from a tubular conduit to an annulus. The apparatus includes a switching assembly configured to alternate between a first operating state where the first volume is in fluid communication with the annulus and a second operating state where the first volume is in fluid communication with the tubular conduit, to alternate a direction of differential pressure between the first volume and the second volume and cause the magnetic shuttle to move in a reciprocating motion and generate an electric current.
