  • Publication number: 20130118726
    Abstract: A gravel pack assembly has a longitudinal body that disposes in a borehole. A wellscreen and other components can connect to the body to complete the assembly. One or more packoff seals or bushings disposed in the body's inner passage can engage a smooth external surface of a crossover tool when disposed therein. This sealing prevents passage of sand and fluids between the tool and the assembly's inner passage. Moreover, the smooth external surface makes the tool less likely of becoming stuck in the inner passage. The packoff seals or bushings can be fixed or activated by movement to engage the smooth external surface of the crossover tool.

  • Publication number: 20130000899
    Abstract: A gravel packing assembly gravel packs a horizontal borehole. Operators wash down the borehole using an inner string in a first position by flowing fluid from the inner string through the apparatus' toe. Operators then gravel pack by moving the inner string to one or more flow ports between a screen and the toe. Slurry flows into the borehole from the flow ports, and returns from the borehole flow through the screen. The gravel in the slurry can pack the borehole in an alpha-beta wave from toe to heel. In another condition, operators can move the inner string to a second flow port so slurry can flow into the borehole through a shunt extending from the second flow port. When gravel packing is done, operators move the inner string to a port collar in a liner of the assembly to cement the liner in the borehole.

  • Patent number: 8225870
    Abstract: A method for making gravel filters in oil well bores. The first step involves ascertaining the location of a producing formation adjacent to a cemented casing in a well bore. Then, a portion of the casing adjacent to the producing formation is cut, enlarging the bore adjacent to the producing formation. Subsequently, a sufficient amount of gravel is deposited in the enlarged portion of the bore to create an effective filter for a producing tube with a screen at its distal end. The distal end is positioned adjacent to the cemented bottom of the well bore. The method maximizes the diameter of the gravel deposited by delivering it exteriorly of the screen of the producing tube and through the annular space defined and sealed between the screen and the casing.

  • Publication number: 20120103606
    Abstract: A gravel pack assembly gravel packs a horizontal borehole. Operators wash down the borehole using a tool in a first position by flowing fluid from the tool through the apparatus' toe. Operators then gravel pack by moving the tool to a first flow port between a screen and the toe. Slurry flows into the borehole from the first flow port, and returns from the borehole flow through the screen. The gravel in the slurry can pack the borehole in an alpha-beta wave from toe to heel. When the tool has a sleeve, operators can break any bridges by flowing fluid from the passage of the assembly into the tool. In another condition, operators can move the tool to a second flow port. Slurry can flow into to the borehole through a shunt extending from the second flow port. Meanwhile, returns can flow from the borehole through a bypass in the assembly.

  • Publication number: 20120103608
    Abstract: A gravel pack operation disposes slurry from an inner string into the annulus around a shoe track. A valve on the shoe track can open and close flow through a port, and seats around the port allow an outlet of the tool to seal with the port. When the valve is open and the outlet sealed with the port, the slurry in the string is pumped into the borehole around the shoe track by flowing the slurry from the outlet into the borehole through the flow port. As this occurs, gravel collects around the shoe track, and fluid returns in the borehole flow back into the shoe track through a screen disposed toward the track's toe. Once inside the shoe track, the fluid returns communicate through a bypass on the shoe track around the sealed outlet and port. At this point, the fluid returns can pass uphole in the gravel pack assembly.

  • Publication number: 20120103603
    Abstract: A downhole assembly, such as a toe-to-heel gravel pack assembly, has a body with a body passage, outlet ports for slurry, and screens for fluid returns. An inner string deploys in the body to perform the toe-to-heel gravel packing. A telescoping adjustment device allows the inner string to space out properly when deployed to the toe of the assembly. Sealing surfaces of a locating device in the body separate a sealable space and seal against seals on the inner string movably disposed therein. Fluid pumped in the string produces a pressure buildup when the string's port communicates with the sealable space. The pressure buildup indicates that the tool is positioned at a first location in the assembly, and other positions for placement of the tool can then be calculated therefrom.
