  • Patent number: 7243742
    Abstract: A retrievable drill pipe screen is adapted for releasable connection within a drill pipe string. The screen has a planar support plate for connecting a perforated tubular screen body to a fish neck wherein the plane of the planar support plate is generally parallel to the axis of the screen body. The orientation of the planar support plate provides minimal resistance to fluid flowing into the screen body while also reducing vortex effects that cause wear of screen components. Preferably, a wear distributor sleeve is fit within the screen body for protecting against wear of the screen caused by fluid flow and a retaining rod can secure the bottom of the screen body to the fish neck in the event that a lower portion of the screen body becomes detached.

  • Patent number: 6202742
    Abstract: The present invention provides a gravel pack assembly for use in a wellbore having a packer positioned therein with a minimum inside diameter and a primary packing seal. In one embodiment, the gravel pack assembly comprises a pack-off conduit that is coupable to the packer. The pack-off conduit has a maximum outer diameter that is sufficient to prevent the pack-off conduit from traversing the minimum inside diameter of the packer. The gravel pack assembly further includes a seal positioned about an inside diameter of the pack-off conduit. The seal is engageable with an outer surface of a tool that is passable through the pack-off conduit to inhibit fluid flow between the seal and the tool, uphole from the primary packing seal. The primary packer seal is typically near the uphole end of the packer and is the seal that isolates the downhole zones from the pressure exerted by the fluid uphole from the primary packer seal.

  • Patent number: 5676208
    Abstract: A gravel packing apparatus and associated method of gravel packing a subterranean well prevents screen collapse without requiring sealing engagement of a washpipe with an external seal, without requiring reliance solely on differential pressure, and without utilizing a reciprocating valve. In a preferred embodiment, a gravel packing apparatus has a tubular mandrel, a tubular housing attached to the mandrel and defining an annular space between the mandrel and housing, a sleeve slidably disposed on the mandrel and extending into the annular space, first and second seals disposed on the sleeve, and a screen slidably disposed on the mandrel and attached to the sleeve for sliding displacement therewith.

  • Patent number: 5579844
    Abstract: A well completion system which includes a production packer assembly, production tubing sealed to the packer assembly, and an isolation assembly coupled with the packer assembly. The isolation assembly includes an isolation pipe received within a production screen and sealed at both ends therewith. The isolation pipe defines at least one port and carrying a moveable sleeve defining at least one aperture. The sleeve is moveable between an open position in which the port and aperture are in communication to permit fluid flow therethrough, and a closed position in which the port and aperture are not in communication and fluid flow is prevented. The isolation system is also coupled with a wash down shoe and a shearable ball seat.

  • Patent number: 5327960
    Abstract: A gravel pack screen assembly includes a bit or sub having a flow passage which may accept a wash pipe. The wash pipe may be inserted past a flapper-type closure member which moves to a closed position upon withdrawal of the wash pipe after completion of the installation of the gravel pack assembly. The closure member can be formed of a porous material to permit the flow of liquid through the bit or sub flow passage into the interior of the gravel pack screen but to prevent flow of gravel packing or produced sand into the interior of the screen. The closure member may serve as a backup to a conventional one-way valve and permit additional gravel pack material to be placed in the flow passage upon completion of the gravel pack installation and in the event of early or late failure of the one-way valve.

  • Patent number: 4860831
    Abstract: Device combinations and methods for wellbore operations for simplifying production methods and workover operations and for production from a failed secondary zone. Using a commercially available prior art coil tubing unit, a coil tubing string is run into an already-in-place production tubing string. The coil tubing string has a commercially available prior art sand control device at the bottom, a portion of blank pipe and a commercially available prior art releasable hydraulic running and release tool ("hrart"). A commercially available prior art small washpipe is connected to the hrart. Wash fluid flows through the hrart, to the wash pipe, and then out of the washpipe thereby washing the sand control device into place in filter media at the perforated production zone. An isolation packer or packers are set between the production tubing and coil tubing string.

  • Patent number: 4825944
    Abstract: A method and apparatus for completing an in situ leach well to prevent production of sand and to insure minimum permeability damage to the ore bearing zone during casing and cementing operations. A hole for the casing is drilled to and terminated at a point (e.g. onefoot) just above the ore zone. If a pilot hole has been drilled to locate the ore zone, it is reamed to provide the hole for the casing with the cuttings from the reaming operations dropping into lower portion of the pilot hole which extends through the ore zone, thereby protecting the ore zone from permeability damage normally cause by contact with cement. The hole is then cased and cemented. Next, a hole is drilled from the lower end of the casing into the ore zone and an interval thereof is underreamed. A perforated liner is lowered on a drill stem which has a stinger pipe thereon which extends through the lower end of the liner.
