DETAILED DESCRIPTION OF THE DRAWINGS [0034] Reference is first made to FIG. 1 of the drawings, which illustrates apparatus for facilitating coupling and cementing of downhole tubulars, the apparatus being in the form of an expandable shoe 10 adapted for location on the lower end of a section of expandable bore liner 12 (FIG. 3). As will be described, the shoe 10 permits circulation of fluid while the liner 12 is being run into the bore and then permits selective filling of the annulus 14 (FIG. 3) surrounding the liner 12 with cement before expansion of the liner 12. [0035] The shoe 10 is tubular and includes an expandable coupling 16 at its upper end for connecting the shoe 10 to the liner 12. The lower end of the shoe 10 is provided with a float shoe 18 which is releasably mounted on the shoe 10. Cement outlets in the form of louvred vents 20 are provided in the wall of the shoe 10 and, as will be described, allow cement to be passed from the interior of the shoe 10 into the annulus 14. Three rows of swab cups 22 are provided on the exterior of the shoe 10 below the vents 20 and restrict cement access to the area of the annulus 14 occupied by the swab cups 22. [0036] Reference is now also made to FIG. 2 of the drawings, which is a cross-sectional view of part of the shoe 10 in the vicinity of the cement vents 20. Initially, the vents 20 are isolated from the interior of the shoe 10 by a sleeve 24. Thus, as the shoe 10 and liner 12 are being run into a bore, fluid may be circulated through the supporting drill pipe 26 (FIG. 3), the liner 12, the shoe 10, and the float shoe 18, to facilitate passage of the liner 12 into the bore. [0037] [0037]FIG. 3 of the drawings shows the liner 12 after it has been run into the bore, with the upper end of the liner 12 overlapping the lower end of an existing section of casing 28. If a ball 30 is then dropped from surface and through the drill pipe 26 and liner 12, the ball 30 closes a flow port 32 in the sleeve 24, and an increase in fluid pressure above the sleeve 24 then releases the sleeve from its initial position, and allows fluid communication through the cement vents 20; the sleeve 24 is caught in the shoe 10, below the vents 20. [0038] A predetermined volume of cement slurry is then passed down the drill pipe 26 and into the liner 12 and shoe 10, the cement flowing from the shoe 10 into the annulus 14, via the vents 20. The cement displaces the fluid occupying the annulus 14, which is free to pass upwardly between the upper end of the liner 12 and the casing 28. However, the swab cups 22, which are dimensioned to engage the bore wall 33, prevent cement from flowing into the portion of the annulus occupied by the swab cups 22. Further, as the ball 30 has closed the sleeve 24, cement cannot flow down through the lower end of the shoe 10. [0039] The cement slurry is followed through the drill pipe 26 by a drill pipe wiper dart 34, as illustrated in FIG. 4, which is adapted to engage a liner wiper plug 36 provided at the upper end of the liner 12. On the dart 34 engaging the plug 36, the plug 36 is released and passes down through the liner 12 with the dart 34. The plug 36 and dart 34 move downwardly through the shoe 10 until encountering the isolation sleeve 24, the plug 36 and dart 34 being positioned relative to the vents such that the wiper blades on the plug 36 prevent further passage of cement slurry or fluid from the shoe 10 through the vents 20. [0040] A rotary expander 40 which serves to mount the liner 12 on the drill string 26 is then activated to expand the liner 12 to provide initial engagement with the casing 28, and then by rotating and advancing the expander 40 the liner 12 is expanded to a larger diameter, while the cement slurry is still liquid. The expander 40 is a rotary expandable device, as described in our applications Nos. WO00\37772 and U.S. Ser. No. 09\469,526, the disclosures of which are incorporated herein by reference. [0041] As illustrated in FIG. 5, on the expander 40 reaching the vents 20, the expansion of the liner 12 closes the vents 20, creating a seal between the cement slurry in the annulus 14 and the interior of the shoe 10. As the expander 40 continues, it engages the plug 36 and dart 34, and the isolation sleeve 24, which are together pushed into the float shoe 18. Continuing advancement of the expander 40 shears the shoe 18 from the end of the liner 12, and the expander 40 engages the shoe 18. If the expander 40 is then deactivated, the drill pipe 26 may be retrieved, together with the expander 40 and the float shoe 18 containing the sleeve, dart and plug 24, 34, 36. [0042] As may be clearly seen from FIG. 5, the described cementation process leaves the annulus surrounding the lower end of the shoe 10 clear of cement and occupied only by the deformable swab cups 22. Thus, when a further length of expandable liner or tubing is run into the bore, and placed in overlapping relation with the lower end of the shoe 10, the upper end portion of the further liner may be expanded and in turn expand the lower end of the shoe 10 to create a secure, sealed coupling between the liner sections. [0043] Reference is now made to FIG. 6 of the drawings, which is a schematic sectional view of an arrangement 50 for facilitating expansion of cemented tubing in accordance with an embodiment of a further aspect of the present invention. The arrangement comprises a tubing section; in this case a section of metal bore-lining casing 52, carrying a sleeve 54 of a deformable material. Cement slurry 56 has been circulated in the annulus 58 between the casing 52 and the bore wall 60; around the sleeve 54, the cement 56 is kept spaced from the outer surface of the casing 52, however there is sufficient spacing between the surface of the sleeve 54 and the bore wall 60 to allow circulation of cement slurry 56 past the sleeve 54. Indeed, the sleeve 54 may serve as a centraliser, as the tubing section is being run in and may for example define external flutes. [0044] As with the first described embodiment, the casing 52 may be expanded before the cement slurry 56 has set. Further, the provision of the sleeve 54 allows for further subsequent expansion of the casing 52 in the region of the [0045] sleeve 54 after the cement has hardened; such expansion of the casing 52 is accommodated by deformation and flow of the sleeve material, as illustrated in FIG. 7 of the drawings. [0046] [0046]FIG. 7 illustrates a profile 62 which has been created by expansion of the casing 52 into the volume occupied by the sleeve, which profile 62 may be utilised for mounting a tool or device in the casing 52. [0047] In other embodiments, a number of spaced deformable sleeves may be provided on a casing section, or a sleeve may be provided over the length of the casing section. With the latter embodiment, this arrangement would allow the expansion or further expansion of the cemented casing at any point on its length. This would allow for the creation of an overlapping expanded coupling at any part of the casing such that, for example, if a subsequent section of casing became jammed or could not otherwise be run in to the anticipated depth, the subsequent casing section could be expanded to its full diameter, even in the event that there was extensive overlap with the existing casing. [0048] It will be apparent to those of skill in the art that the above described embodiments are merely exemplary of the present invention and that various modifications and improvements may be made thereto without departing from the scope of the invention. In particular, both aspects of the invention have application in a wide range of tubulars in addition to the forms described above.
