  • the downhole expandable tubular may be a patch to be expanded within a casing or well tubular structure in a well, a liner hanger to be at least partly expanded within a casing or well tubular structure in a well, or a casing to be at least partly expanded within another casing.
  • the metal tubular blank may have an outer blank diameter which is larger than the first outer diameter.
  • the metal tubular blank may have a blank thickness which is larger than a thickness of the expandable tubular when metalworking has been performed.
  • the present invention also relates to an annular barrier to be expanded in an annulus between a well tubular structure and an inside face of a casing or borehole downhole for providing zone isolation between a first zone and a second zone of the casing or borehole, the annular barrier having an axial extension and comprising:
  • the annular barrier according to the present invention may comprise an expansion opening in the tubular part through which fluid may enter the space in order to expand the expandable tubular.
  • the tubular part may be made of metal.
  • end sections of the downhole expandable tubular may be welded to the tubular part.
  • the end sections of the downhole expandable tubular may be shrinked onto the tubular part.
  • connection parts may be configured to protect the downhole expandable tubular when it is being submerged.
  • the annular barrier as described above may further comprise at least one sealing element surrounding the downhole expandable tubular.
  • a sleeve may be arranged between the downhole expandable tubular and the tubular part, the sleeve being connected with the tubular part and the downhole expandable tubular, thus dividing the space into a first space section and a second space section.
  • the downhole expandable tubular may have an opening providing fluid communication between the first or the second zone and one of the space sections.
  • the projection may be a ring-shaped projection of an increased thickness in relation to other parts of the downhole expandable tubular, the ring-shaped projection providing an enforcement of the annular barrier when the annular barrier is expanded.
  • the present invention also relates to a downhole completion system comprising
  • the tubular part of the annular barrier may be mounted as part of the well tubular structure.
  • the completion system may comprise a plurality of annular barriers.
  • the present invention furthermore relates to a manufacturing method for the manufacture of the downhole expandable tubular according to the present invention, comprising the steps of:
  • the step of metalworking may comprise the steps of cold-working the intermediate section to a thickness which is smaller than that of the end sections, heat treating the intermediate section and cold-working the end sections.
  • the step of metalworking may comprise the steps of cold-working the intermediate section and the end sections and heat treating the intermediate section.
  • the heat treatment of the intermediate section may be performed by annealing, e.g. induction annealing.
  • the method as described above may further comprise the step of machining the downhole expandable tubular, providing it with at least one circumferential projection or groove.
  • Fig. 1 shows a cross-sectional view of a downhole expandable tubular 1 to be at least partly expanded in a well 2 (as shown in Fig. 5 ) downhole from a first outer diameter D 1 to a second outer diameter D 2 (shown in Figs. 6 and 12 ) to abut against an inner face of a casing or borehole.
  • the downhole expandable tubular has an axial extension 22, and along the axial extention the downhole expandable tubular has a first end section 31 and a second end section 32, and an intermediate section 33 between the first end section and the second end section.
  • the downhole expandable tubular 1 is made from one metal tubular blank 6 (shown in Fig. 2 ) of one metal material.
  • the metal material of the blank has the same properties through-out the metal tubular blank.
  • the metal material of the end sections 31, 32 has a higher yield strength than the metal material of the intermediate section after after metalworking of the end sections 31, 32 and/or the intermediate section 33, so that when expanded, the end sections are more reluctant to expand.
  • connection parts 30 (shown in Fig. 12 ) connecting the expandable sleeve to the tubular part or base pipe and controlling the expansion of the ends of the expandable sleeve are no longer required, since the restriction in expansion is thus incorporated in the end sections of the downhole expandable tubular in the form of the expandable sleeve.
  • the end sections have a higher yield strength than the intermediate section, so the end sections restrict and control the expansion at the ends, while the intermediate section of the expandable sleeve/downhole expandable tubular 1 is not restricted during expansion and can therefore comply with the requested expansion ratio.
  • the ends of the downhole expandable tubular 1 can therefore be fastened by a simple welded connection 39 (shown in Fig. 6 ) to the tubular part of the annular barrier and the end sections having a higher yield strength thus prevents these ends from departing from the tubular part and destroying the welded connection.
  • a simple welded connection 39 shown in Fig. 6
  • Such simple design with welded ends is especially useful when manufacturing an annular barrier having a small outer diameter, since the connection parts take up more space than the downhole expandable tubular 1 which is welded directly to the tubular part.
  • the metalworking is performed by means of one of the following processes: cold-working, heat treating, annealing, induction annealing or any combination thereof.
  • the end sections are cold-worked and/or the intermediate section is heat-treated, annealed or induction-annealed.
  • the end sections may be metalworked so that the metal material of the end sections has a higher yield strength than the metal material of the intermediate section.
  • the yield strength of the metal material of the end sections is at least 25% higher than the yield strength of the material of the intermediate section, preferably at least 40% higher than the yield strength of the material of the intermediate section, and more preferably at least 50% higher than the yield strength of the material of the intermediate section.
  • the yield strength of the metal material of the end sections is at least 350 MPa at room temperature.
  • the metal tubular blank may be cast, such as made by spin or centrifugal casting. As the material cools down or is quenched, the metal tubular blank is formed as shown from one end in Fig. 2 . Impurities 18 in the material are located near the surface of the blank, and as the blank is machined and material is removed to form the downhole expandable tubular having projections as shown in Fig. 3 , the impurities are also removed, leaving a tubular to have a very low content of impurities.
  • This tubular made of a very uniform material or "pure" material with a low content of impurities is indicated with the dotted lines 19 in Fig. 2 .
  • the material with the low content of impurities has a higher ductility than the border material having a higher impurity content.
  • the metal tubular blank may also be cold-worked or heat treated without the blank first being machined.
  • One way of obtaining a downhole expandable tubular with end sections having a higher yield strength is to cold-work the intermediate section of the metal tubular blank into a thickness which is smaller than that of the end sections, then heat treat the intermediate section, and subsequently cold-work the end sections into having a higher yield strength than the intermediate section.
  • Another way of obtaining a downhole expandable tubular with end sections having a higher yield strength is to cold-work the intermediate section and the end sections of the metal tubular blank into a thickness which is smaller than that of the blank, and then heat treat the intermediate section, e.g. by means of annealing or induction annealing, whereby the intermediate section obtains a lower yield strength than the end sections.
  • the yield strength along the axial extension of the downhole expandable tubular is thus controlled so as to match the need to control the radial expansion of e.g. an annular barrier providing isolation of a zone 103, such as a production zone 400 as shown in Fig. 5 .
  • annular barrier providing isolation of a zone 103, such as a production zone 400 as shown in Fig. 5 .
  • two annular barriers 100 are used to isolate the production zone 400.
  • a fracturing valve or section 600 also called a frac port, is arranged between the annular barriers, so that when the annular barriers have been expanded, the frac port 600 is opened and fluid is let into the formation for creating fractures in the formation to ease the flow of hydrocarbon-containing fluid, such as oil, into the well tubular structure.
  • the fracturing valve or section 600 may also comprise an inlet section which may be the same as the frac port.
  • a screen may be arranged so that the fluid is filtered before flowing into the casing.
  • Both annular barriers have downhole expandable tubulars as expandable sleeves, which downhole expandable tubulars are connected to the tubular part of the annular barrier by means of a welded connection in each end.
  • the annular barriers are expanded by pressurising the well tubular structure 4 and allowing the pressurised fluid to enter through expansion openings 23 in the tubular part and thus hydraulically expand the downhole expandable tubular.
  • the end sections of the downhole expandable tubular 1 form the transition from a fully extended sleeve to the welded connection to the tubular part.
  • the downhole expandable tubular After processing the downhole expandable tubular with end sections having a higher yield strength by means of cold-working and/or heat treatment, the downhole expandable tubular may be machined, providing it with at least one circumferential projection or groove 8 as shown in Fig. 4 .
  • the downhole expandable tubular 1 has six projections 7 and two grooves 8, and the blank is indicated with dotted lines illustrating the material which has been metalworked and maybe also machined away to form the downhole expandable tubular 1 in one piece without subsequent use of connection parts or welded connection of rings creating projections and grooves.
  • the downhole expandable tubular is merely fastened at its ends to the tubular part by a simple welded connection.
  • the downhole expandable tubular By machining the downhole expandable tubular from a blank having a substantially larger wall thickness, the downhole expandable tubular can be made with increased thickness, projections and grooves without having to weld rings onto the downhole expandable tubular, which may result in the subsequent deterioration of the expansion ability of the downhole expandable tubular.
  • the tubular blank of Fig. 2 has an inner diameter D i and an outer diameter D o , and the blank may be machined so as to increase the inner diameter D i and decrease the outer diameter D o to remove the material with the highest content of impurities.
  • the machining is performed by means of milling, cutting, grinding, latheing or by means of similar machining methods for removing material from the blank to form the downhole expandable tubular.
  • metal material is being removed from the tubular blank in a lathe machine 50 to form the expandable tubular 1.
  • the tubular blank is fastened between two points 51, and a lathe bit 52 is machining material away from the blank 6. As shown in Fig.
  • the tubular blank may be a solid cylinder or a hollow cylinder as shown in Fig. 2 .
  • the tubular blank is made from any suitable metal material, such as steel or stainless steel.
  • the downhole expandable tubular has a length l, and the downhole expandable tubular 1 is machined along the entire length, thus removing material from the blank to form the downhole expandable tubular 1 of a "pure" material.
  • a sealing element 9 is arranged in the groove 8 and between two projections 7.
  • the thicknes t of the expandable tubular 1 is not the same in the groove as between two adjacent projections which are not adjacent the same groove.
  • the sealing element 9 may be arranged merely between two adjacent projections, so that the downhole expandable tubular 1 does not have grooves and thus has the same thickness t between the projections 7 and opposite the sealing element 9, as shown in Fig. 6 .
  • a ring-shaped retainer element 10 is arranged between two adjacent projections 7 or in the groove 8 for pressing the sealing element 9 in the axial extension towards an edge 11 of the projection or groove.
  • the retainer element 10 functions as a back-up ring for the sealing element, so that the sealing element 9 is not squeezed in between the expandable tubular and the inner face of the borehole or casing when the expandable tubular is expanded.
  • the retainer element is a split ring with several windings and is made of a metal material.
  • the retainer element 10 When the expandable tubular is expanded by 30%, the retainer element 10 is partly “unwound” by 30% of the circumference of the retainer element 10, and thus the retainer element decreases its number of windings so that it is still capable of pressing the sealing element against the edge of the groove or the projection.
  • a retainer element 10 is arranged on opposite sides of the sealing element 9 squeezing the sealing element along its circumferential edges.
  • Each retainer element 10 in Fig. 8 has approximately 3.5 windings, and after expansion of the expandable tubular, the retainer element 10 has approximately 2.7 windings and thus maintains its extension in the axial extension of the expandable tubular even though the retainer element has been partly unwound.
  • the retainer element may also be made of a spring material, so that when the downhole expandable tubular 1 is expanded, the retainer element is also expanded, resulting in an inherent spring force in the retainer element.
  • the spring effect of the metal is not essential to the operation of the retainer ring.
  • a back-up element 12 is arranged between the ring-shaped retaining element 10 and the sealing element 9.
  • the sealing element 9 is typically made of an elastomeric material and the retainer element is made of a metallic material, and in order to protect the sealing element, the back-up element arranged therebetween is made of non-metallic material which is less flexible than the sealing material.
  • the downhole expandable tubular 1 may be a patch which is expanded within a casing part of a well tubular structure in a well.
  • the patch is typically used for sealing off a leak or a perforated zone of openings in the casing.
  • the downhole expandable tubular is inserted into the casing having a first diameter, and when positioned opposite the openings, the expandable tubular is expanded to a second and larger diameter until the sealing elements are sqeezed in between the downhole expandable tubular and the inner face of the casing. Since the sealing elements are arranged between projections on opposite sites of the perforated zone of openings, the zone is sealed off and the well fluid from the formation is prevented from flowing in through the openings.
  • the downhole expandable tubular 1 may also be a liner hanger where the downhole expandable tubular has been partly expanded within an upper casing forming part of a well tubular structure in a well.
  • Fig. 6 shows a cross-sectional view of an annular barrier 100 which has been expanded in an annulus 101 between a well tubular structure 300 and an inside face 3 of the borehole 5.
  • the annular barrier provides zone isolation between a first zone 102 and a second zone 103 of the borehole.
  • the annular barrier has an axial extension 22 which coincides with the longitudinal extension of the casing and well tubular structure.
  • the annular barrier comprises a tubular part 20, which may be a separate tubular part or a casing part for mounting a part of the well tubular structure 300.
  • the annular barrier comprises the downhole expandable tubular 1 which surrounds the tubular part, and each end 31, 32 of the expandable tubular 1 is connected with the tubular part by means of welded connections.
  • the downhole expandable tubular 1 and the tubular part 20 enclose an annular barrier space 21, and an expansion opening 23 is provided in the tubular part through which fluid may enter the space in order to expand the expandable tubular as shown in Fig. 6 .
  • the downhole expandable tubular 1 is expanded until the sealing elements or the projections abut the inner face 3 of the borehole 5, so that fluid is prevented from flowing freely from the first zone 102 to the second zone 103.
  • the end sections 31, 32 and the intermediate section 33 have substantially the same thickness along the axial extension of the downhole expandable tubular 1.
  • the intermediate section 33 comprises subsections 38 having a higher yield strength than the intermediate section 33.
  • the subsections 38 do not expand as much as the rest of the intermediate section 33.
  • the subsections 38 therefore change the cross-sectional shape of the expanded downhole expandable tubular 1 into a more bulged shape, creating cavities between the downhole expandable tubular 1 and the inner face 3 of the borehole 5, strengthening the downhole expandable tubular 1 and substantially increasing the collapse rating of the annular barrier of Fig. 10 .
  • the yield strength of the subsections is lower than that of the end sections.
  • the subsections are distributed along the axial extension of the intermediate section with a predetermined distance between them, creating several cavities in which sealing elements 9 are arranged.
  • the intermediate section may extend between the subsections, so that the expandable tubular has varying yield strengths along the axial extension.
  • connection parts 30 may be configured to protect the downhole expandable tubular when it is being submerged, and the connection parts may also be provided with helical grooves to ease the insertion of the well tubular structure 4 into the borehole.
  • the annular barrier further comprises a sleeve 25 arranged between the downhole expandable tubular 1 and the tubular part 20.
  • the sleeve 25 is connected with the tubular part 20 and the downhole expandable tubular 1, thus dividing the space into a first space section 21a and a second space section 21b.
  • the sleeve is squeezed in between the tubular part and the downhole expandable tubular.
  • the sleeve 25 may also be connected with the tubular part in another manner, such as shrink-fitted onto the tubular part.
  • the downhole expandable tubular has an opening 24 providing fluid communication between the first or the second zone and one of the space sections, thus equalising the pressure between the space and that zone.
  • the pressure in one of the zones in which hydraulic fracturing is performed is increasing, and in order to prevent the expandable tubular from collapsing, the fluid is let in through the opening 24 and into the first space section 21a.
  • the sleeve 25 moves towards the tubular part, thus yielding to the increased pressure in the first space section 21a, and the first space 21a increases until the pressure equalises or the sleeve abuts the tubular part.
  • the annular barrier space of the annular barrier may comprise at least one thermally decomposable compound adapted to generate gas or super-critical fluid upon decomposition.
  • This compound may be thermally decomposable below a temperature of 400°C and above 100°C, preferably above 180°C.
  • the downhole expandable tubular of the annular barrier may be expanded by supplying heat to the annular barrier instead of pressurised fluid.
  • the compound may comprise nitrogen in the form of ammonium, nitrite, azide or nitrate or be selected from a group consisting of: ammonium dichromate, ammonium nitrate, ammonium nitrite, barium azide, sodium nitrate, or a combination thereof.
  • the metal material of the end sections after being metal worked has a yield strength of 250-1000 MPa at room temperature, preferably 300-700 MPa at room temperature.

  • blank is meant a preform or similar intermediate product.
  • Cold-working may be performed by rollers pressing on the outer face of the blank or downhole expandable tubular while the rollers are moved along the axial extension, extending the length of the blank or downhole expandable tubular along the axial extension and decreasing the thickness of the blank or downhole expandable tubular.
  • the expansion of the downhole expandable tubular may be performed by tool isolation of a section of the well tubular structure opposite the opening 23 in the tubular part 20 of the annular barrier of Fig. 6 , and then pressurising that section.
  • fluid or well fluid any kind of fluid that may be present in oil or gas wells downhole, such as natural gas, oil, oil mud, crude oil, water, etc.
