- the disclosures of all of which (01-121) are herein incorporated by reference in their entirety.
- Field of the Invention [003] This invention relates to expandable tubular members, and in particular to a method of expanding tubular members.
- Cement annuli may be provided between the outer surfaces of the casings and the borehole wall to seal the casings from the borehole wall.
- a relatively large borehole diameter is required at the upper part of the wellbore.
- Such a large borehole diameter involves increased costs due to heavy casing handling equipment, large drill bits and increased volumes of drilling fluid and drill cuttings.
- increased drilling rig time is involved due to required cement pumping, cement hardening, required equipment changes due to large variations in hole diameters drilled in the course of the well, and the large volume of cuttings drilled and removed.
- wellbore casings may be formed in the wellbore by radially expanding and plastically deforming tubular members in the borehole. These tubular members are often coupled to one another by threaded connections.
- the threaded engagement between properly secured tubular members in a conventional casing joint is effective in maintaining a secure mechanical connection that holds the string together and effectively seals the internal casing area from the formation wellbore environment.
- a conventional connection changes dimensionally in a way that can prevent the engaged components of the connection from properly engaging and sealing.
- the radial expansion of a conventional connection may weaken or otherwise damage the connection sufficiently to permit mechanical separation or leakage in the connection.
- connection may fail during and/or after the radial expansion and plastic deformation.

- Fig. 5 is a sectional view through a borehole illustrating a partially expanded string of casing and an expandable expansion device.
- Fig. 6 is a sectional view through a borehole illustrating a string of casing being radially expanded and plastically deformed with two expansion devices.
- a string of casing 12 is positioned within the borehole 10.
- the string of casing 12 includes a first tubular member 14 and a second tubular member 16.
- the first tubular member 14 and the second tubular member 16 are connected by a conventional mechanical connection 18, for example a conventional threaded connection.
- a second step is illustrated where a portion of the first tubular member 14 above the connection 18 has been radially expanded and plastically deformed into engagement with the borehole 10, and a portion of the second tubular member 16 below the connection 18 has been radially expanded and plastically deformed into engagement with the borehole 10.
- the connection 18 has not been radially expanded and plastically deformed.
- the connection 18 is shown in tension.
- the first tubular member 14 is exerting a force on the connection 18 in the direction of an arrow 20.
- the second tubular member 16 is exerting a force on the connection 18 in the direction of an arrow 22.
- connection 18 is in tension because as a portion of the first tubular member 14 is expanded and plastically deformed in a radial direction into engagement with the borehole 10, that portion contracts in an axial direction due to Poisson's ratio, and exerts a tensional force on the connection.
- the connection 18 is in tension because as a portion of the second tubular member 16 is expanded and plastically deformed in a radial direction into engagement with the borehole 10, that portion contracts in an axial direction due to Poisson's ratio, and exerts a tensional force on the connection.
- both the first tubular member 14 and the second tubular member 16 are held stationary, for example by being expanded into engagement with the borehole 10, in order for the connection 18 to be in tension.
- a third step is illustrated where the string of casing 12 has been radially expanded and plastically deformed within the borehole 10.
- the first tubular member 14 and the second tubular member 16 were radially expanded and plastically deformed into engagement with the borehole 10, as shown in Fig. 2, and then the connection 18 was radially expanded and plastically deformed, as shown in Fig. 3.

- An expansion device 22 is used to radially expand and plastically deform portions of the string of casing 12.
- suitable expansion devices for the expansion device 22 include conventional expansion devices adjustable between a small diameter configuration and a large diameter configuration. It is also understood that when the expansion device 22 is in the small diameter configuration, the expansion device can fit through the unexpanded connection 18, as shown in Figs. 1 and 2; and when the expansion device is in the large diameter configuration, the expansion device can expand a portion of the first tubular member 14, second tubular member 16, and/or the connection 18, as shown in Figs. 2 and 3.
- a first part of the technique is illustrated where a portion of the second tubular member 16 below the connection 18 is being radially expanded and plastically deformed by the expansion device 22.
- the expansion device 22 is shown in the large diameter configuration.
- the expansion device 22 is mounted to a support number 23. It is understood that an area 24 under the expansion device 22 may be pressurized to force the expansion device towards the connection 18 and the first tubular member 14. Alternatively, the expansion device 22 may be pulled by the support member 23 towards the connection 18 and the first tubular member 14.
- the expansion device 22 may be lowered through the string of casing 12 in the small diameter configuration, then the expansion device may be expanded to the large diameter configuration, and used to expand a portion of the second tubular member 16.
- the expansion device 22 may start in the large diameter configuration, and the string of casing 12 may be placed over the support number 23, so that the expansion device is at the bottom of the string of casing, then the expansion device can be pulled through the second tubular member 16 to radially expand and plastically deform the second tubular member.
- Fig. 5 a second part of the technique is illustrated where the expansion device 22 is in a small diameter configuration moving through the connection 18.
- the expansion device 22 may be used to radially expand and plastically deform a portion of the second tubular member 16 while in a large diameter configuration during the first part of the technique as illustrated in Fig.4, then be collapsed into a small diameter configuration and be pulled through the connection 18 by the support number 23, during the second part of the technique as illustrated in Fig. 5.
- the expansion device 22 may be re-expanded into the large diameter configuration and used to radially expand and plastically deform a portion of the first tubular member 14, during a third part of the technique.
- connection 18 may be radially expanded and plastically deformed with the expansion device 22 or with another expansion device (not shown), during a fourth part of the technique.
- FIG. 6 there is illustrated a second technique of radially expanding and plastically deforming the string of casing 12 of Fig. 1.
- a portion of the string of casing 12 is radially expanded and plastically performed with a first expansion device 26 and a second expansion device 28.
- the first expansion device 26 is mounted on a support member 34.
- the second expansion device 28 is connected to the first expansion device 26 in a conventional manner by a connecting device 30.
- first expansion device 26 is expandable between a small diameter configuration and a large diameter configuration
- second expansion device 28 may or may not be expandable between a small diameter configuration and a large diameter configuration.
- the first expansion device 26 is used to radially expand and plastically deform a portion of the second tubular member 16 while in a large diameter configuration.
- the first expansion device 26 is then retracted into a small diameter configuration and moved through the connection 18.
- the first expansion device 26 is expanded into a large diameter configuration and used to radially expand and plastically deform a portion of the first tubular member 14, after moving through the connection 18.
- the second expansion device 28 is pulled by the connecting device 30 behind the first expansion device 26. It is understood that the second expansion device 28 has a fixed diameter. Alternatively, the second expansion device 28 is movable between a first small diameter configuration and a second large diameter configuration.
- the first expansion device 26 After the first expansion device 26 has radially expanded and plastically deformed a portion of the second tubular member 16 and a portion of the first tubular member 14 during the third part of the second technique, during a fourth part the second expansion device 28 is pulled through the connection 18 by the connecting device 30, and the second expansion device radially expands and plastically deforms the connection.
- the string of casing After moving the first expansion device 26 and the second expansion device 28 through the string of casing 12 (shown in Fig. 6) using the second technique, the string of casing may look like the string of casing 12 as illustrated in Fig. 3.
- first expansion device 26 and the second expansion device 28 may be moved through the string of casing 12 by pulling them with the support member 34.
- the first expansion device 26 and the second expansion device 28 are moved through the string of casing 12 by pressurizing an area 32 under the second expansion device, which pushes the second expansion device, the connecting device 30, and the first expansion device.
