Definitions
- the invention relates to a method and system for cladding an inner surface of an underground wellbore passage.
- the invention further relates to a sleeve for cladding an inner surface of an underground wellbore passage .
- US 2011/0297400 discloses an inflatable packer for use in wellbores to isolate specific wellbore regions.
- the inflatable packer has an expandable bladder which is expanded, e.g. inflated, into sealing engagement with a surrounding surface inside the wellbore (such as the wellbore wall surface) .
- the expandable bladder is pre-manufactured with a radially enlarged section relative to the axial ends of the expandable bladder when the bladder is in relaxed state.
- the radially enlarged section offers a reduction in required expansion ratio that is required to transition the packer into sealing engagement with the surrounding surface by inflating. Inflating can be accomplished by excersising an axial force along the packer.
- the packer of US 2011/0297400 is not suitable for some applications, as it requires continuous energizing to maintain the packer into sealing engagement with the surrounding surface .
- a method for cladding an inner surface of an underground wellbore passage comprising:
- an elastic sleeve comprising a stretching device within the sleeve which stretching device is connected to opposite ends of the sleeve;
- an elastic sleeve for cladding a inner surface of an underground wellbore passage the sleeve having a larger outer width than the width of the inner surface and being:
- the underground wellbore passage may be formed by the wellbore itself, or by a wellbore tubular arranged within the wellbore.
- a system for cladding an inner surface of an underground wellbore passage comprising an elastic sleeve as defined above and a stretching device arranged within the sleeve, which stretching device is releasably connected to opposite ends of the sleeve.
- Fig. 1 schematically shows a longitudinal section A-A through a system for cladding an underground wellbore passage
- Fig. 2 schematically shows a top view of the system of Fig. 1 in the longitudinal direction;
- FIG. 3 schematically shows a perspective view of the system of Fig. 1;
- Fig. 4 schematically shows a longigudinal section of a wellbore after cladding with the system of Fig. 1;
- Fig. 5 schematically shows the same view on the wellbore after inserting a cement slurry.
- An inner surface of an underground wellbore passage (which can be the wellbore itself or a wellbore tubular) is cladded by an elastic sleeve, which is placed by:
- the elastic sleeve When detached from the stretching device, the elastic sleeve has an outer width that exceeds the inner width of the inner surface of the wellbore passage in a location where cladding is desired.
- Figures 1, 2 and 3 show an elastic sleeve 1, as example, which has end sections 1A, IB in which tensioning rods 2 are embedded at regular
- the tensioning rods 2 are configured to be coupled to a stretching device 4.
- the sleeve 1 is stretchable by longitudinal expansion of the stretching device.
- the stretching device 4 comprises two flanges 7,8 longigudinally spaced from each other and between which the sleeve can be
- the tensioning rods 2 are configured with heads 6 at their distal ends relative to the sleeve 1.
- the tensioning rods 2 are held in the longitudinal slots 5 with the heads 6 preventing slipping of the tensioning rods 2 through the slots in longitudinal direction.
- the flanges 7,8 are longitudinally moved away from each other to stretch the sleeve 1 by creating longitudinal tension.
- the outer diameter of the flanges is smaller than the outer diameter of a middle section of the sleeve.
- the stretching device 4 may automatically slide out of the slots 5 in radial direction. This way, the stretching device 4 may automatically detach from the sleeve 1 upon releasing the longitudinal tension.
- the tension rods 2 may be kept in place by virtue of friction between the heads 6 and the flanges 7, 8.
- some recesses may be provided on the flanges 7, 8 for retaining the heads 6.
- a V-shaped groove 3 may be present to mitigate formation of ridges in between the rods 2 during stretching of the sleeve 1.
- a V-shaped groove may be arranged in each interval of each end section.
- the sleeve may comprise an elastic elastomer and a swelling agent that induces the elastomer to swell upon contact with water and/or another wellbore fluid.
- the swelling agent may be a water absorbing agent such as a super absorbent polymer or a hygroscopic salt which is dispersed in the elastic elastomer as an array of finely divided solid particles.
- the sleeve 1 may be made of a rubber or other elastomeric material and comprise an additive that swells upon contact with water or another well fluid as described in Patent
- a self-healing elastomer sleeve 1 An objective of the use of a self-healing elastomer sleeve 1 is to seal any micro-annuli and/or other leak paths on a cement casing interface directly after placing a cement plug inside the steel casing, liner or pipe. Any leak paths that may subsequently occur during the life of a well, e.g. induced by temperature or pressure changes, will be restored by the self-healing
- the elastomer sleeve 1 may swell in the presence of oil, water, brine and/or water condensed from an wet natural gas phase.
- the elastomeric sleeve 1 Before running into a wellbore the elastomeric sleeve 1 according to the invention is longitudinally stretched by a mechanical stretching tool 4 that pulls the opposite sets of rods 2 in longitudinal direction away from each other.
- the increase in length of the sleeve 1 causes a significant decrease in its Outer
- the stretched elastomer sleeve 1 can be Run Into Hole (RIH) to the desired downhole location within the wellbore. At the required downhole location the tension is released by longitudinal contraction of the stretching tool 4, which reduces the distance between the opposite sets of rods 2 thereby inducing the elastomer sleeve 1 to radially re-expand and regain its original length and Outer Diameter (OD), thereby creating a clad on the inner surface of the surrounding casing, liner, pipe or the formation.
- RHIH Rich Hole
- OD Outer Diameter
- the elastomer sleeve 1 detaches from the stretching device 4, after which the stretching device 4 may be withdrawn from the elastomer sleeve 1 and optionally retrieved from the wellbore 10 as shown in Fig. 4.
- the elastomer sleeve 1 stays behind in the wellbore.
- the sleeve may be cladded against the inner surface of an uncased wellbore section or of a well casing, liner or other well tubular.
- the sleeve may suitably be configured to swell upon contact with water and/or another wellbore fluid.
- the wellbore 10 may be a wellbore of an abandoned
- the sleeve 1 may be induced to swell and thereby seal any micro-annuli between the cement plug and the inner surface.
- the self-healing elastomer sleeve 1 allows the use of ordinary (low cost) Portland class G cement slurries to provide long-term zonal-isolation.
- Other types of cement or well bore plugging materials for example bentonite, barite or resins, may also be used.
