International Classification:

E21B 2304

US Classification:

166387, 166 51, 166120, 166123, 166188, 166317

Abstract:

A packer for use inside a casing of a subterranean well includes a resilient element, a housing and a rupture disc. The resilient element is adapted to seal off an annulus of the well when compressed, and the housing is adapted to compress the resilient element in response to a pressure exerted by fluid of the annulus of a piston head of the housing. The housing includes a port for establishing fluid communication with the annulus. The rupture disc is adapted to prevent the fluid in the annulus from entering the port and contacting the piston head until the pressure exerted by the fluid exceeds a predefined threshold and ruptures the rupture disc.

US Classification:

166298, 166297, 166361, 166 55, 166 63

Abstract:

Apparatuses and methods allow a downhole anchor device to be cut, released, and retrieved using a single one-trip cutter and removal assembly. The assembly preferably includes a cutter head recessed behind an anchor latch. The latch is landed to the anchor device to be removed and the cutter head is extended therefrom and activated. Once cut by the cutter head, the anchor device is retrieved upon a distal end of the assembly.

International Classification:

E21B 33/12

US Classification:

166387, 277343

Abstract:

A seal assembly that is usable with a well includes a metal body that is adapted to expand radially inwardly and radially outwardly in response to the body being longitudinally compressed between compressing surfaces. The metal body includes first and second surfaces that do not conform to the compressing surfaces before longitudinal compression of the body and are adapted to contact the compressing surfaces.

E21B 33/13

US Classification:

166387, 166187, 166191, 166285

Abstract:

The invention is a sealing system, such as a packer, that is used in a wellbore to seal against an exterior surface, such as a casing or open wellbore. The sealing system includes a swellable material that swells from an unexpanded state to an expanded state thereby creating a seal when the swellable material comes into contact with a triggering fluid.

International Classification:

E21B 23/00

US Classification:

166377, 166118, 166134

Abstract:

Disclosed herein are methods and apparatus for releasing a releasable packer. The apparatus may include shear screws, a mechanism for isolating the shear screw from a shearing force. The mechanism for isolating the shear screw from a shearing force is selectively unlockable to expose the shear screw to the shearing force. The methods may include unlocking a mechanism protecting at least one shear screw, applying a shearing force to the at least one shear screw, and shearing the at least one shear screw.

International Classification:

E21B 33/128

US Classification:

166387000, 166179000, 166196000

Abstract:

A packer that is usable with a well includes a resilient seal element and a support member. The resilient seal element is adapted to radially expand in response to the longitudinal compression of the element. The support member is at least partially surrounded by the seal element and is adapted to radially expand with the seal element to support the element. The support sleeve is substantially harder than the seal element.
