摘要： A gravel pack well tool comprised of a workstring having a gravel pack screen thereon wherein the workstring can be rotated without applying any substantial torque to the screen jacket which forms part of the gravel pack screen. This allows the workstring to be rotated in either direction during installation or removal of the gravel pack screen without damaging the screen jacket. The gravel pack screen is comprised of a fluid-permeable base pipe having a screen jacket rotatably mounted thereon.

摘要： A method of making a screen for downhole use uses mesh screen layers that are diffusion bonded to each other. The ends that will overlap to make a seam when the sheets that are attached together are rolled into a tube are compressed before the tube shape is created or thereafter when the tube shape and an inner base pipe are drawn through a die to join the seam made by the overlapping edges. Because of the compression of the edges, when they overlap to form a tube the wall thickness at the overlap is about the same as the remaining thickness of the screen portion. Optionally, a resilient material can be compressed into the open areas of the screen portions that will be overlapped to make the generally longitudinally oriented seam. The seam can be parallel to the screen axis or spiral around it. The outer perforated shroud provides a compressive force that maintains a barrier resistant to flow of sand particles between the seam overlapping surfaces as the outer perforated shroud, filtration tube and inner base pipe assembly is drawn through a die.

摘要： A downhole completion method and an expandable filtration apparatus are disclosed. The filter assembly comprises a plurality of layers beginning with a coated perforated base pipe. The coating reduces the force required for expansion. A drainage layer overlays the base pipe with the filtration layer above it. The drainage layer improves flow through the filtration layer and protects it from burrs in the base pipe. A filtration enhancement layer fits over the filtration layer and an outer shroud protects the assembly during run in. The assembly can be used as made or expanded downhole in one or a series of expansions.

摘要： A method and apparatus for effecting the completion of non-vertical, including horizontally disposed, portions of a deviated well bore traversing a production formation. To facilitate the insertion of a gravel packing tool string through the curved portion of the well bore, stabilizer elements are maintained in a radially retracted position and then operated to engage the well bore after the tool string is run-in. An anti-rotation tool may be incorporated for connecting the work string to the left hand threads conventionally provided on a conventional packer in order to permit rotation of the entire tool string to facilitate passage through the curved portion of the well bore. Two gravel packing modifications are disclosed, the one employing a single packer and a cross-over tool located at the top end of a plurality of serially connected screens. In the other modification, a plurality of gravel packing sections, including stabilizers, screens, a sleeve valve housing and a packer are serially connected together and run-in. A cross-over tool is then inserted by a separate tubular work string to be initially positioned adjacent the lowermost packer to accomplish the packing of the lowermost screens and then moved to the next packer to successively effect the gravel packing of all of the gravel packing sections.

摘要： A firing mechanism for a downhole perforating gun comprises two cooperating housing sections having closed end walls in abutment. The lower housing section contains a booster charge and the primer cord for firing the gun. The upper housing section contains a detonatable primer, a hammer, and a downwardly directed explosive charge positioned between the primer and the bottom end wall of the upper housing. The upper housing is secured to the lower housing by a collet latch which, if firing of the gun does not occur, can be released by the exertion of a substantial upward force on a fishing neck provided in the assemblage of the upper housing. The defective elements can then be repaired or replaced, the upper housing reinserted in the well by wireline, and latched into an operative position with respect to the lower housing to permit another attempt to fire the perforating gun.

摘要： A well perforating gun assembly includes a perforating gun secured to the bottom of a tubular actuating housing containing a fluid pressure actuated hammer and a fixedly mounted primer against which the firing means is impacted. A latch normally maintains the firing means in an elevated position with respect to the primer but such latch may be released through the application of sufficient fluid pressure force to the firing means to drive it into engagement with the primer. If the primer fails to ignite, a second fluid pressure force is employed to move the firing means to its original latched position, ready for a second application of fluid pressure to release the firing means and again impact the primer.

摘要： A device and system for controlling fluid flow into a wellbore tubular may include a flow path in a production control device and at least one in-flow control element along the flow path. A media in the in-flow control element adjusts a cross-sectional flow area of the flow path by interacting with water. The media may be an inorganic solid, a water swellable polymer, or ion exchange resin beads. A method for controlling a fluid flow into a wellbore tubular may include conveying the fluid via a flow path from the formation into a flow bore of the wellbore; and adjusting a cross-sectional flow area of at least a portion of the flow path using a media that interacts with water. The method may include calibrating the media to permit a predetermined amount of flow across the media after interacts with water.

摘要： Casing or other well tubulars that have failed are repaired in a manner that doesn't reduce the final inside diameter and doesn't further propagate the failure. The tubular needing repair is first expanded on at least one zone above and below the damaged area. This expansion in an undamaged area arrests failure propagation when the damaged area is then expanded. After the damaged area is expanded, the patch coupled preferably with exterior seals is positioned in the expanded zone of the damaged tubular and expanded. The procedure can also be accomplished in a single trip into the well.

摘要： A method and apparatus for manufacturing any given length of a completion filter assembly is described. An outer perforated jacket is assembled over the filter media, which is itself placed over a coarse support screen or drainage layer. In the preferred embodiment, the drainage layer and outer jacket have end rings such that when advanced through a die are pushed together with the filter media in between to effect a seal of the subassembly. The subassembly can then be placed on a support pipe which is perforated, and if metallic, the end rings are welded to the support pipe to complete the assembly. Optionally, many of the components can be made of materials which lend buoyancy to the assembly so that when it is advanced into a long lateral, it will float to assist in its proper positioning.
