Abstract: A backup including a resister articulated to a mounting ring, a support articulated to a support ring and the resister, the resister moving upon one of the mounting ring and the support ring moving away from the other. A seal including a mandrel, an element and a backup disposed on the mandrel adjacent the element. A borehole system including a borehole in a formation, a string in the borehole, a backup disposed within or as a part of the string. A backup including a deformable ring, a resister disposed adjacent the deformable ring, the resister being articulated to a ring mount through a pivot pin having a frustoconical geometry. A backup including a resister articulated to a ring, the resister including a borehole wall engager. A borehole system including a borehole in a subsurface formation, a string in the borehole, a backup within or as a part of the string.

Abstract: An open tip downhole expansion tool incudes a frustoconical member having a base and a tip, the member having a radially outer zone and a radially inner zone and having an axial length extending from the base to the tip; an outer compliance area in a material of the member along a length of the radially outer zone; and an inner compliance area in a material of the member along a length of the radially inner zone, the outer and inner compliance areas being located at different positions along the axial length of the frustoconical member, the outer and inner compliance areas each causing the frustoconical member to present a first resistance to deformation when the compliance areas are in a first condition and a higher resistance to deformation of the frustoconical member when the compliance areas are in a second condition.

Abstract: An open tip downhole expansion tool including a frustoconical member having a base at a diametrically smaller portion of the frustoconical member and a tip at a diametrically larger portion of the frustoconical member, the member having a radially outer zone and a radially inner zone and having an axial length extending from the base to the tip; an outer void in a material of the member along a length of the radially outer zone; and an inner void in a material of the member along a length of the radially inner zone, the outer and inner voids being located at different positions along the axial length of the frustoconical member, the outer and inner voids each causing the frustoconical member to present a first resistance to deformation when the voids are open and a higher resistance to deformation of the frustoconical member when the voids are collapsed.

Abstract: A backup including a capture ring, and a backup ring articulated to the capture ring.

Abstract: A packer including a packer element, a mandrel about which the packer element is disposed, an intensifier configuration on the mandrel.

Abstract: An anti-extrusion ring including a ring body having a cross sectional shape, a radial contact surface making up a part of the cross sectional shape of the ring body the radial contact surface being configured to preferentially load a radial edge portion of the radial contact surface when the anti-extrusion ring is loaded, an axial contact surface making up a part of the cross sectional shape, the axial contact surface being configured to preferentially load an axial edge portion of the axial contact surface when the anti-extrusion ring is loaded, and an element load surface positioned between the radial edge portion and the axial edge portion and method for creating a seal.

Abstract: Portable physical and occupational therapy systems and methods with an adjustable balance pole assembly utilized as a target in combination with a number of manipulable objects, such as rings, that engage the target, for the purpose of exercising patients through a range of motions and through a range of cognitive actions. A basic therapy tool set incorporates a target pole of variable height, pivotally positioned on a target base. Each therapy tool set includes a number of therapy rings sized and structured to engage the target pole. The angle of the target pole may be varied by releasing a pole angle lock. The basic therapy tool set may be utilized alone or in combination with additional sets. A basic kit that may be utilized by a therapist could preferably involve three complete therapy tool sets assembled and positioned in an array around a therapy patient.

Abstract: Devices and methods for setting a packer inside a wellbore with little appreciable reduction of the useable area of the wellbore. The outer casing or liner of the wellbore contains one or more integrated casing coupler joints having an increased diameter chamber portion. A large bore packing element is carried within the increased diameter chamber portion. The packing element may be selectively actuated to form a seal against an interior tubular member. Because the packing element is located within the chamber portion of the casing coupler, the packer may be set while saving useable cross-sectional area within the casing.
