  • DETAILED DESCRIPTION
  • [0028]
    Referring initially to FIG. 1, a conventional device 100 for drilling a borehole 102 in a subterranean formation 104 is shown. The borehole 102 may be lined with a casing 106 at the top portion of its length. An annulus 108 formed between the casing 106 and the formation 104 may be filled with a sealing material 110, such as, for example, cement. In an exemplary embodiment, the device 100 may be operated in a conventional manner to extend the length of the borehole 102 beyond the casing 106.
  • [0029]
    Referring now to FIG. 2, a device 200 for coupling an expandable tubular member 202 to an existing tubular member, such as, for example, the existing casing 106 , is shown. The device 200 includes a shoe 206 that defines a centrally positioned valveable passage 206 a adapted to receive, for example, a ball, plug or other similar device for closing the passage. An end of the shoe 206 b is coupled to a lower tubular end 208 a of a tubular launcher assembly 208 that includes the lower tubular end, an upper tubular end 208 b, and a tapered tubular transition member 208 c. The lower tubular end 208 a of the tubular launcher assembly 208 has a greater inside diameter than the inside diameter of the upper tubular end 208 b. The tapered tubular transition member 208 c connects the lower tubular end 208 a and the upper tubular end 208 b. The upper tubular end 208 b of the tubular launcher assembly 208 is coupled to an end of the expandable tubular member 202. One or more seals 210 are coupled to the outside surface of the other end of the expandable tubular member 202.
  • [0030]
    An expansion device 212 is centrally positioned within and mates with the tubular launcher assembly 208. The expansion device 212 defines a centrally positioned fluid pathway 212 a, and includes a lower section 212 b, a middle section 212 c, and an upper section 212 d. The lower section 212 b of the expansion device 212 defines an inclined expansion surface 212 ba that supports the tubular launcher assembly 208 by mating with the tapered tubular transition member 208 c of the tubular launcher assembly. The upper section 212 d of the expansion device 212 is coupled to an end of a tubular member 218 that defines a fluid pathway 218 a. The fluid pathway 218 a of the tubular member 218 is fluidicly coupled to the fluid pathway 212 a defined by the expansion device 212. One or more spaced apart cup seals 220 and 222 are coupled to the outside surface of the tubular member 218 for sealing against the interior surface of the expandable tubular member 202. In an exemplary embodiment, cup seal 222 is positioned near a top end of the expandable tubular member 202. A top fluid valve 224 is coupled to the tubular member 218 above the cup seal 222 and defines a fluid pathway 226 that is fluidicly coupled to the fluid pathway 218 a.
  • [0031]
    During operation of the device 200, as illustrated in FIG. 2, the device 200 is initially lowered into the borehole 102. In an exemplary embodiment, during the lowering of the device 200 into the borehole 102, a fluid 228 within the borehole 102 passes upwardly through the device 200 through the valveable passage 206 a into the fluid pathway 212 a and 218 a and out of the device 200 through the fluid pathway 226 defined by the top fluid valve 224.
  • [0032]
    Referring now to FIG. 3, in an exemplary embodiment, a hardenable fluidic sealing material 300, such as, for example, cement, is then pumped down the fluid pathway 218 a and 212 a and out through the valveable passage 206 a into the borehole 102 with the top fluid valve 224 in a closed position. The hardenable fluidic sealing material 300 thereby fills an annular space 302 between the borehole 102 and the outside diameter of the expandable tubular member 102.
  • [0033]
    Referring now to FIG. 4, a plug 402 is then injected with a fluidic material 404. The plug thereby fits into and closes the valveable passage 206 a to further fluidic flow. Continued injection of the fluidic material 404 then pressurizes a chamber 406 defined by the shoe 206, the bottom of the expansion device 212, and the walls of the launcher assembly 208 and the expandable tubular member 202. Continued pressurization of the chamber 406 then displaces the expansion device 212 in an upward direction 408 relative to the expandable tubular member 202 thereby causing radial expansion and plastic deformation of the launcher assembly 208 and the expandable tubular member.
  • [0034]
    In an exemplary embodiment, the pressure in chamber 406 is cycled between a minimum Pmin and maximum pressure Pmax over a length 410 of the expandable tubular member 202, during operation of the device 200.
  • [0035]
    Referring now to FIG. 5, the radial expansion and plastic deformation of the expandable tubular member 202 is then completed and the expandable tubular member is coupled to the existing casing 106. The hardenable fluidic sealing material 300, such as, for example, cement fills the annulus 302 between the expandable tubular member 202 and the borehole 102. The device 200 has been withdrawn from the borehole and a conventional device 100 for drilling the borehole 102 may then be utilized to drill out the shoe 206 and continue drilling the borehole 102, if desired.
  • [0036]
    Referring now to FIG. 6, in an exemplary embodiment, the interior of the expandable tubular member 202 is pressure cycled using a pressure source 602 positioned within and/or operably coupled to the interior of the expandable tubular member, to generate a pressure cycle signal 604. In an exemplary embodiment, the pressure source 602 may comprise a hydraulic, pneumatic, or impulse type pressure source. In an exemplary embodiment, a controller 606 is coupled to the pressure source 602 for controlling the operation of the pressure source. In an exemplary embodiment, the controller 606 operates the pressure source 602 to generate a pressure cycle signal 604 to control one or more of the following material properties: collapse strength, burst strength, yield strength, and wall thickness of the expandable tubular member 202.
  • [0037]
    Referring now to FIG. 7, in an exemplary embodiment, the controller 606 operates the pressure source 602 to generate a sinusoidal pressure cycle signal 700 within the expandable tubular member 202. In an exemplary embodiment, the sinusoidal pressure cycle signal 700 varies from a maximum value Pmax to a minimum value Pmin over time.
  • [0038]
    Referring now to FIG. 8, in an exemplary embodiment, the controller 606 operates the pressure source 602 to generate a square wave pressure cycle signal 800 within the expandable tubular member 202. In an exemplary embodiment, the square wave pressure cycle signal 800 varies from a maximum value Pmax to a minimum value Pmin over time.
  • [0039]
    Referring now to FIG. 9, in an exemplary embodiment, the controller 606 operates the pressure source 602 to generate a triangular pressure cycle signal 900 within the expandable tubular member 202. In an exemplary embodiment, the triangular pressure cycle signal 900 varies from a maximum value Pmax to a minimum value Pmin over time.
  • [0040]
    In an exemplary embodiment, the controller 606 may operate the pressure source 602 to generate a pressure cycle signal 604 that includes one or more of the pressure cycle signals 700, 800, and 900.
  • [0041]
