Definitions
- This invention relates to bore liner, and in particular to expandable bore liner.
- expandable bore-lining tubing Recent developments in the oil and gas exploration and extraction industries have included the provision of expandable bore-lining tubing.
- One such system proposes expandable bore liner being run into a section of open hole, below a cased section of bore, such that the upper end of the liner overlaps with the lower end of the existing casing, as described in GB 2 344 606 A.
- the lower end of the liner is anchored in the bore, and cement slurry is circulated into the annulus between the liner and the bore wall, displaced fluid from the annulus passing through the gap between the lower end of the casing and the upper end of the unexpanded liner.
- the liner is run into the bore with an expansion cone or swage located at the lower end of the liner and, once the cement slurry is m place, the expansion cone is urged upwardly through the liner, by supplying hydraulic fluid at an elevated pressure behind the cone. This expands the liner to a larger inner and outer diameter, and brings the outer face of the upper end of the liner into contact with the inner face of the lower end of the casing. The cement then cures, sealing and securing the expanded liner in the bore.
- the expansion cone moves upwardly from the lower end of the liner, such that any expansion problems may result in the cone becoming stuck part way through the liner. Access to remedy the problem is then restricted by the presence of the cone and the smaller diameter unexpanded liner above the cone. Circumferential expansion of the liner using a cone results in axial shrinkage of the liner.
- difficulties may be experienced if the liner becomes differentially stuck in the bore, that is if there is a differential pressure between the bore and a formation intersected by the bore, and this pressure differential acts on the liner to hold the liner against a portion of the bore wall.
- the axial shrinkage of the liner will thus be resisted between the differentially stuck portion of the liner and the anchor at the lower end of the liner. This may result in the liner breaking, or in the expansion process being curtailed with the cone onlv part-wa ⁇ through J the liner .
- a method of lining a drilled bore comprising: running an expandable first tubular of an external first diameter into a bore; locating the first tubular in an unlined section of the bore with an upper end of the first tubular overlapping a lower end of an existing second tubular of an internal second diameter larger than said first diameter; securing the upper end of the first tubular relative to the lower end of the second tubular while retaining fluid outlets to permit displacement of fluid from an annulus between the first tubular and the bore wall; running an expansion device down through the first tubular to expand the first tubular to a larger diameter; circulating cement into the annulus between the expanded first tubular and "the Pore wall; sealing the upper end of the first tubular to the lower end of the second tubular.
- the liner may be expanded to conform to the surrounding bore wall, or the liner may carry or be provided with a sleeve of deformable or expanding material, such as an elastomer which may be formulated to swell on exposure to selected fluids or temperatures.
- a sleeve of deformable or expanding material such as an elastomer which may be formulated to swell on exposure to selected fluids or temperatures.
- the first tubular is expanded by rotary or rolling expansion, that is an expansion device featuring one or more rotatable expansion members, the device being rotated within the tubular as the device is axially advanced there through.
- rotary expansion devices are described in applicant's O00 ⁇ 37766 and US 09 ⁇ 469,690, the disclosures of which are incorporated herein by reference.
- Such expansion devices operate using a different expansion mechanism than cones and swages, that is by reducing the wall thickness of the tubular and thus increasing the diameter of the tubular, rather than simple circumferential extension of the tubular wall.
- Such devices may be controlled to limit the degree of axial shrinkage or contraction of the tubular during expansion, and thus the impact of any differential sticking is x ⁇ du e .,- .and. the different yield mechanism .of iotajri expansion is also better able to accommodate localised differential sticking.
- the rotary expansion device may be compliant, that is be capable of expanding a variable diameter, or of fixed- diameter.
- expansion cones or swages may still be utilised to expand the first tubular, or an axial compliant expander may be utilised, such as the tool sold under the ACE trade mark by the applicant, or the tool as described in the PCT and United States patent applications filed on 30 November 2002, based on applicant's UK patent application 0128667.3.
- the first tubular may be expanded by a combination of mechanical and hydraulic means, as described in applicant's PCT patent application O02 ⁇ 081863.
- the upper end of the first tubular is expanded to an internal diameter sufficient such that there is little or no reduction in internal diameter between the second tubular and the expanded first tubular.
- the lower end portion of the second tubular may describe a larger diameter than an upper portion of the tubular, to create a "bell-end" or the like, such that the first tubular may be expanded into the Peii- end.
- the upper end of the first tubular may be expanded within the lower end of the second tubular and induce expansion and deformation of the second tubular.
- the_ upper end of the first tubular is expanded to secure the upper end of the first tubular relative to the lower end of the second tubular.
- the upper end of the first tubular is further extended to seal the upper end of the first tubular to the lower end of the second tubular.
- the lower end of the first tubular may be expanded to a larger internal diameter, to accommodate the upper end of a subsequent tubular.
- the first tubular is liner and the second tubular is casing.

- Figures 1 to 7 of the drawings are schematic illustrations of steps in the process of lining a drilled bore in accordance with a preferred embodiment of the present invention.
- Figure 1 of the drawings illustrates the lower end of a bore 10 including an open or unlined bore section 12. Above the unlined section 12, the bore 10 has been lined with casing 14, which has been sealed relative to the adjacent bore wall using conventional cementation techniques. It will be noted that the lower end of the casing 14 features a larger diameter end section 16, or bell-end.
- Figure 2 shows a section of expandable liner 18 which has been run into the bore 10 on an appropriate running string 20. The liner 18 is initially coupled to the running string 20 via a setting tool 22 (the tool 22 will be described in greater detail below, following the description of the process, with reference to Figure 8 of the drawings) .
- the liner 18 is run into the bore 10 on the string 20 and located in the bore such that the upper end of the liner 18 overlaps the larger diameter casing end section 16.
- the setting tool 22 includes a fluid pressure actuated compliant, rolling, expansion device 23 which _is_ rotatably coupled to the string 20 but which is rotatable relative to the setting tool 22 and liner 18.
- the expansion device 23 When actuated and rotated, the expansion device 23 extends at least a portion of the upper end of the liner 18 into contact with the casing end section 16, thus providing an anchor 24 for the liner 18.
- An axial push and pull is then applied to the tool 22 from surface to ensure that the liner 18 is firmly anchored to the casing 14.
- the setting tool 22 is then released from the now anchored liner 18 and the compliant rolling expansion device 23 utilised to expand the section of liner 18 above the anchor 24, to locate the liner 18 more securely relative to the casing 14.
- an elastomeric seal sleeve 25 below the anchor 24 remains inactive, and a number of fluid ports 27 in the liner remain open to allow fluid to pass from the annulus 26 between the liner 18 and the bore wall between the overlapping ends of the casing 14 and liner 18.
- the setting tool 22 is moved downwardly through the liner 18 and a fixed diameter expansion device 25 is utilised to expand the liner 18 to a larger diameter, such that the expanded inner diameter of the liner 18 corresponds to the inner diameter of the casing 14.
- the expansion of the liner 18 is achieved using a rolling expansion device 25 but may equally feature one or both of fixed and compliant rolling -elements-. -If jco pl .i ant- r_o11 i ng, aLer ⁇ an ⁇ 3_axa -pxej ⁇ Le ,- t ese. are actuated to extend radially outwardly of the tool body by hydraulic pressure supplied to the tool 22 via the running string 20.
- the lower end of the liner 18 is provided with an expandable drillable float shoe 28, of a suitable material such a composite or aluminium alloy.
- the shoe 28 incorporates a float collar with a flapper valve, and the check valves normally found in a shoe.
- a sealed connection is formed with the float collar, the flapper valve is opened and a cement port in the setting tool 22 is opened, such that cement slurry may be pumped down the running string 20, through the setting tool 22, through the float shoe 28, and into the annulus 26, as illustrated in Figure 5. .
- the fluid from the annulus displaced by the cement 30 passes through the flow ports 27 in the liner 18 below the anchor 24.
- the setting tool 22, with the compliant expansion device 23 retracted, is pulled out of the lower end of the expanded liner 18 and the flapper valve in the float shoe closes. Cleaning fluid is then circulated through the liner 18 and casing 14, via the tool 22, to clean out any remaining cement residue.
- the compliant expansion device 23 is then pulled out until the device 23 is located adjacent the liner seal 25.
- the expansion device 23 is then actuated to further expand the upper end of the liner 18 into contact with the surrounding casing 14 to activate the seal 25 and close the liner flow ports 27, and thus form a fluid seal between the liner 18 and the casing 14.
- the setting tool 22 is then pulled out of the bore 10.
- the casing 14 is provided with a larger diameter lower end section 16, into which the upper end of the liner 18 is expanded, such that the expanded liner 18 has the same internal diameter as the casing 14.
- 7% inch liner 18 may be run through a 9% inch casing 14. The 7% inch liner 18 may then be expanded to provide the same internal dimensions as the 9% inch liner.
- Figure 8 of the drawings illustrates details of a setting tool 22 as may be utilised in the above-described method.
- the tool 22 will be described from the top down, starting with Figure 8a.
- the upper end of the tool 22 extends above the upper end of the liner 18 and features a location device in the form of a spring-loaded latch 50 which is shaped to locate in a profile (not shown) provided in the lower end of the casing 14. This serves to indicate when the tool 22, and thus the liner 18, has been correctly located relative to the casing 14; once the latch 50 has engaged the casing profile, an over-pull or additional weight is required to iii.alcLdge- the- la ⁇ _ch_ 5fL_ from . the. _px ⁇ fi le .
- _____L__e__ coxxe t location of the tool 22 and the liner 18 in the casing 14 is important as, for example, if the overlap between the liner 18 and casing 14 is not as intended, it may not be possible to fully expand the liner 18, leaving a restriction in the liner bore.
- the location device may take other forms, and may utilise sensors relaying signals to surface rather than relying on mechanical engagement .
- the fixed diameter expansion tool 25 which in this example features three rollers 52 mounted on inclined spindles.
- a pair of torque anchors 56, 58 which are rotatably fixed relative to the arrangement for supporting the liner on the tool 22 ( Figure 8c), in the form of liner- supporting dogs 60, but which are mounted to the remainder of the tool 22 via a swivel.
- the anchors 56, 58 comprise rollers 62 which define circumferentially extending teeth.
- the rollers are mounted on pistons and are each rotatable about an axis which lies parallel to the axis of the tool 22 and the liner 18.
- the anchors 56, 58 may be hydraulically actuated to extend radially into contact with the inner surface of the casing 14.
- the liner-supporting dogs 60 initially extend through windows 64 in the upper end of the liner 18, which will form the liner hanger.
- the dogs 60 may be released by a-ppi-i-ca-tio-n- -of- -an- ithi .
- the_ -tj-L 2-2 - Xn_ this example such an over-pressure shears a disc which then creates an impulse pressure on a dog-supporting sleeve, to move the sleeve to a position in which the dogs may radially retract.
- the dogs may be released by some other means, for example by rotating the tool 22 to the left relative to the anchored liner 18.
- the liner-supporting dogs 60 and the torque anchors 56, 58 operate in concert when the compliant expansion device 23 ( Figure 8d) is first activated; the elevated pressure utilised to activate the expansion device 23 also serves to activate the anchors 56, 58 to engage with the casing 14, such that when the activated device 23 is rotated to expand the anchor C-ring 24, the liner 18 is held stationary.
- the rollers 62 allow the actuated anchors 56, 58 to move upwardly relative to the casing 14 as the activated device 23 is utilised to expand the liner 18 above the anchor 24.
- a cement stinger 70 ( Figures 8d and 8e) is provided below the expansion device 23, and is mounted to the remainder of the lower end of the tool 22 via a swivel 72.
- the stinger 70 stabs into an appropriate pack-off bushing at the liner shoe 28 fee- -a-l-l w- -c-eme-nt- to- fee- p-ump-e - -f-r-om- -sur-f-a-Ge--i-n-to- the- -a-n- nuisanceu-s- 26 .
- the compliant expansion tool 23 is utilised to further expand the upper end of the liner, and in particular to activate the seal 25 and close the liner flow ports 27. This follows the tool 22 being accurately located relative the upper end of the liner 18 and the casing 14 by means of the latch 50.
- FIGS 9 and 10 of the drawings illustrate an alternative arrangement, in which the casing 114 is initially of substantially constant diameter over its length.
- the lower end of the casing 116 is also subject to a degree of expansion, such that the upper end of the expanded liner 118 describes the same internal diameter as the unexpanded casing 114.
- the annulus around the lower end of the casing 114 is free of set cement or other incompressible materials.
- the casing has been provided with a shoe, such as described in applicant's PCT ⁇ GB01 ⁇ 04202 , the disclosure of which is incorporated herein by reference, to retain the lower portion of the casing annulus free of cement.
- FIG. 11 showing liner 218 which has been expanded in a similar manner to the first described embodiment.
- the lower end of the liner 220 is then subject to further expansion, to facilitate accommodation of a further expanded liner, and such that the further expandable liner may be expanded to a similar internal diameter to the first expanded liner 218 and the existing casing 214.
- the expansion of the lower end of the liner may be achieved by means of a compliant expansion tool 23, as described above.
- the cementation step may not be required, for example when the liner is provided with an elastomer on its outer face, which elastomer may be formulated to swell on contact with certain fluids to fill the annulus between the expanded liner and the bore wall.
- the cementation may be carried in stages, particularly when the liner is relatively long. In such a situation • the expansion may also be carried out in stages, that is a section of liner is expanded and then cemented, and this process is then repeated as many times as is necessary for subsequent sections.
- an exterior sleeve is provided around the ports, allowing fluid to flow through the ports. However, when the liner is expanded the liner is brought into contact with the sleeve and the sleeve closes the ports.
