摘要： A safety joint having threads with a first handedness, for example right-handed threads, to connect the safety joint to an upper drill pipe portion and a lower drill pipe portion. The safety joint includes a releasable threaded connection having a second handedness inverse of the first handedness. The safety joint also includes a hydraulically actuated piston sleeve that locks rotation across the releasable threaded connection. Disconnecting the upper drill pipe portion from the lower drill pipe portion is achieved by moving the piston sleeve to a position wherein the piston sleeve does not transmit rotation across the releasable threaded connection, and rotating the upper drill pipe portion in the first handedness direction to unscrew the releasable threaded connection.

摘要： An apparatus for expanding tubular members in a wellbore, such as casing, liners, sand screens, or other expandable tubular members, includes a first downhole tubular member, a second downhole tubular member that is radially expandable, and a sealed releasable connection coupling the first and second downhole tubular members. The sealed releasable connection is configured to decouple the first and second downhole tubular members by expansion of the second downhole tubular member. The sealed releasable connection had a metal-to-metal seal formed between the first and second downhole tubular members.

摘要： An expansion system is assembled by coupling a piston assembly and a solid cone assembly to an adjustable cone assembly within an expandable tubular having inner sleeve disposed in a portion thereof. The expansion system is run into a wellbore. The piston assembly is activated to move the solid cone assembly downward through the inner sleeve so as to expand the inner sleeve and the portion of the expandable tubular having the inner sleeve. The adjustable cone assembly is shifted from a retracted position to an expansion position within the inner sleeve. The adjustable cone assembly is moved upward through expandable tubular while leaving the solid cone assembly and the inner sleeve coupled to expandable tubular. The solid cone assembly and the inner sleeve may be drilled or milled.

摘要： A data encryption and decryption process, particularly for use in smart cards, in which the data is encrypted using an encryption key derived from a fingerprint template. The fingerprint template is stored, in unencrypted form, in a memory which, apart from the fingerprint template, is filled or substantially filled with random data values thereby to conceal the fingerprint template. The template may be broken up into components stored in disparate locations in the memory to further increase security. Decryption is performed by, firstly, carrying out scanning a fingerprint to obtain a new template, comparing the new template with the previously stored template and, if there is a match, regenerating the encryption key from the previously stored template. The regenerated encryption key is then used to decrypt the data.

摘要： A method of expanding a tubular member by assembling an expansion system having an expansion cone and an expansion sleeve and coupling a tubular member to the expansion system so that the expansion sleeve is at least partially disposed within the tubular member. The expansion system and tubular member are then disposed in a wellbore and the expansion cone is translated relative to the expansion sleeve and tubular member so as to radially expand the tubular member into engagement with the wellbore and the expansion system is removed from the wellbore. The tubular member is expanded to an inside diameter equal to an expansion diameter of the expansion cone plus twice a thickness of the expansion sleeve.

摘要： A system includes a seal bushing that is locked into a pup joint, which is part of a liner assembly including an expandable liner hanger. The system also includes an expansion tool that is connected to a drill pipe. The expansion tool includes an expansion cone attached to the slick joint. The slick joint can slide within the bore of the seal bushing. A ball is dropped into the drill pipe and lands on a seat of the expansion tool to increase hydraulic pressure. The ball and the seal bushing can avoid pressurizing an entire liner connected below the pup joint. When the expansion cone moves through the liner hanger at least in part under the effect of pressure, the liner hanger is expanded and anchored to a base casing.

摘要： Tubulars are used to seal a leak in completion equipment, such as parted connection (or parted casing) or damaged casing, isolate a casing perforation or an open hole zone, by expanding the tubulars over the leak, perforation, or zone, where the inner diameters of sections of the completion equipment above and below the leak, perforation, or zone are different. Alternatively, the tubulars are used to apply a liner over an open hole section and anchor the liner onto a base casing. The tubulars preferably function as cladding. An apparatus for expanding the tubulars includes a lower fixed-diameter cone, an upper fixed-diameter cone, and a drill pipe passing through the upper fixed-diameter cone and attached to the lower fixed-diameter cone. The drill pipe can slide through the upper fixed-diameter cone or be attached to the upper fixed-diameter cone.
