Definitions

  • the present invention relates to an annular barrier to be expanded in an annulus between a well tubular structure and an inside wall of a borehole downhole for providing zone isolation between a first zone and a second zone of the borehole.
  • the invention furthermore relates to a well system and to a method for maintaining a pressure within the annular barrier.
  • annular barriers are used for different purposes, such as for providing a barrier for flow between an inner and an outer tubular structure or between an inner tubular structure and the inner wall of the borehole.
  • the annular barriers are mounted as part of the well tubular structure.
  • An annular barrier has an inner wall surrounded by an annular expandable sleeve.
  • the expandable sleeve is typically made of an elastomeric material, but may also be made of metal. The sleeve is fastened at its ends to the inner wall of the annular barrier.
  • a second annular barrier In order to seal off a zone between an inner and an outer tubular structure or a well tubular structure and the borehole, a second annular barrier is used.
  • the first annular barrier is expanded on one side of the zone to be sealed off, and the second annular barrier is expanded on the other side of that zone, and in this way, the zone is sealed off.
  • annular barriers When expanded, annular barriers may be subjected to a continuous pressure or a periodic high pressure from the outside, either in the form of hydraulic pressure within the well environment or in the form of formation pressure. In some circumstances, such pressure may cause the annular barrier to collapse, which may have severe consequences for the area which the barrier is to seal off as the sealing properties are lost due to the collapse.
  • a similar problem may arise when the expandable sleeve is expanded by means of e.g. a pressurised fluid. If the fluid leaks from the sleeve, the back pressure may fade, and the sleeve itself may thus collapse.
  • the ability of the expanded sleeve of an annular barrier to withstand the collapse pressure is thus affected by many variables, such as strength of material, wall thickness, surface area exposed to the collapse pressure, temperature, well fluids, etc.
  • the collapse rating currently achievable by the expanded sleeve within certain well environments is insufficient for all well applications.
  • the collapse rating may be increased by increasing the wall thickness or the strength of the material; however, this would increase the expansion pressure, which, as mentioned, is not desirable.
  • annular barrier to be expanded in an annulus between a well tubular structure and an inside wall of a borehole downhole for providing zone isolation between a first zone and a second zone of the borehole, comprising
  • Said gas may be nitrogen, neon, argon, krypton, or xenon.
  • the compensation device may be arranged in the space between the expandable sleeve and the tubular part.
  • the compensation device may be arranged as part of a connection part connecting the expandable sleeve with the tubular part.
  • the annular barrier may comprise an additional connection part wherein a second compensation device is arranged.
  • the chamber of the compensation device may be annular, surrounding the tubular part.
  • Said compensation device may have several chambers in which pistons are arranged.
  • This plurality of chambers may be spaced along a circumference of the tubular part.
  • one end of the sleeve may be fixedly fastened to the tubular part and the other end may be slidably fastened to the tubular part, and the second chamber part containing the gas may be arranged closest to the fixedly connected end of the sleeve.
  • the second chamber part may comprise a valve accessible from the inside of the tubular part, allowing refill of the second chamber part with gas.
  • the piston may comprise sealing means to seal the second chamber part from the first chamber part.
  • the present invention also relates to a well system comprising the well tubular structure and the annular barrier described above.
  • the well system according the present invention may further have a tool comprising isolation means isolating an isolated part of the inside of the tubular part outside the aperture to pressurise the isolated part of the inside and the space to expand the expandable sleeve.
  • Said tool may further comprise a pumping device for pumping fluid from the inside of the tubular part being outside the isolated part and into the isolated part to expand the expandable sleeve.
  • the present invention relates to a method for maintaining a pressure within the annular barrier described above, comprising the steps of:
  • Fig. 1 shows an annular barrier 1 to be expanded in an annulus 2 between a well tubular structure 3 and an inside wall 4 of a borehole 5 downhole for providing zone isolation between a first zone 8 and a second zone 12 of the borehole 5.
  • the tubular structure 3 may be a production casing.
  • the annular barrier 1 comprises a tubular part 6 mounted as part of the well tubular structure 3.
  • the tubular part 6 has a longitudinal axis 14 coaxial with the longitudinal axis of the well tubular structure 3.
  • the annular barrier 1 comprises an expandable sleeve 7 surrounding the tubular part 6 and defining a space 13 which is in fluid communication with an inside 23 of the tubular part 6.
  • Each end 9, 10 of the expandable sleeve 7 is connected with the tubular part 6, one end being fixedly fastened to the tubular part and the other end being slidably fastened with the tubular part.
  • the annular barrier 1 has an aperture 11 for letting fluid into the space to expand the sleeve, the aperture 11 being arranged in the tubular part 6 so that the fluid is let directly into the space.
  • the aperture may be arranged so that the fluid is let from the inside of the tubular part through a connection part 15 fastening the expandable sleeve 7 with the tubular part.
  • a valve may also be arranged in the aperture, such as a one-way valve, and when the aperture is the connection part also a two-way valve or three-way valve.
  • the expandable sleeve is typically expanded by pressurising the well tubular structure 3 from the top of the well and in this way inflate several annular barriers at a time.
  • the annular barrier further comprises a compensation device 16 having a chamber 17 in which a piston 18 is arranged dividing the chamber 17 in a first chamber part 19 and a second chamber part 20.
  • the first chamber part 19 is in fluid communication with the space 13 through an opening 21 and the second chamber part 20 comprises gas, such nitrogen.
  • the gas may also be neon, argon, krypton, or xenon.
  • the compensation device 16 is arranged in the space 13 between the expandable sleeve 7 and the tubular part 6.
  • the annular barrier 1 has been expanded by pressurising the inside of the tubular part and thus fluid is flowing into the aperture to pressurise the space 13 to expand the expandable sleeve 7.
  • the pressure in the space may drop accordingly and thus cause a pressure drop in relation to the formation pressure and the pressure in the annulus.
  • the temperature drop may cause the expandable sleeve to collapse locally, undermining its strength, and the pressure to make it collapse, also called the collapse pressure, is somewhat decreased.
  • the piston 18 of the compensation device moves towards the opening, as shown in Fig.
  • the compensation device lets fluid out into the space to equalise the pressure until it is the same as the pressure before the temperature drop.
  • the piston When the temperature increases in the borehole, the piston is forced to move to reduce the second chamber part 20, 20B due to the fact that the gas in the second chamber part diminishes to equalise the pressure inside the space.
  • the annular barrier 1 is arranged in a vertical part of the well.
  • the second chamber part 20 is arranged closest to the fixedly connected end of the expandable sleeve 7.
  • the annular barrier 1 may also be arranged in the horizontal part of the well and then the gas will accumulate underneath the expandable sleeve closest to the borehole wall 4 and will, in the same way as in Fig. 4 , have the ability to expand and thus equalise the pressure.
  • the compensation device is arranged as part of the fixed connection part 24 connecting the expandable sleeve 7 with the tubular part 6, since the slidable connection part 25 slidably connecting the expandable sleeve with the tubular part moves during expansion and thus moves in relation to the aperture in the tubular part if the aperture is arranged in connection with the connection part, and thus the expansion fluid is let in through that connection part.
  • the position of the aperture is thus optional.
  • the annular barrier comprises an additional connection part being the slidable connection part 25 in which a second compensation device 16B is arranged.
  • the second compensation device 16B comprises a chamber 17B in which a piston 18B is arranged dividing the chamber 17B in a first chamber part 19B and a second chamber part 20B.
  • the first chamber part 19B is in fluid communication with the space 13 through an opening 21B and the second chamber part 20B also comprises gas, such nitrogen.
  • the gas may also be neon, argon, krypton, or xenon.
  • the compensation device 16B is arranged in the space 13 between the expandable sleeve 7 and the tubular part 6.
  • the chamber is annular, surrounding the tubular part.
  • the first chamber part 19, 19B and the second chamber part 20, 20B is also annular and the piston 18, 18B moving inside the chamber 17, 17B is a ring-shaped piston surrounding the tubular part 6.
  • the compensation device 16, 16B has a plurality of chambers 17, 17B spaced along a circumference of the tubular part and the connection part 15.
  • a piston 18, 18B is arranged in each chamber 17, 17B diving the chamber into a first and a second chamber part as mentioned above.
  • Fig. 7 is a cross-sectional view of the connection part 15, and by having several chambers instead of one annular chamber, the connection part becomes more rigid and solid and thus capable of withstanding the pressure difference occurring downhole and the bumping when lowering the well tubular structure in order to complete the well.
  • Fig. 8 an embodiment of the compensation device is shown.
  • the piston 18, 18B comprises a sealing means 26, such as an O-ring to seal the second chamber part 20, 20B from the first chamber part 19, 19B.
  • the second chamber part comprises a valve 27 accessible from the inside 23 of the tubular part in order to be able to refill the second chamber part 20, 20B with gas if needed later.
  • the valve may be any kind of suitable valve.
  • the method for maintaining a pressure within the annular barrier 1 mentioned above is firstly to expand the expandable sleeve until the sleeve seals against the inside wall 4 of the borehole, and subsequently, when the temperature decreases or increases in the borehole, to equalise the pressure inside the space by moving the piston 18, 18B and let the gas in the second chamber part expand or diminish.
  • the expandable sleeve 7 has an outer face facing the wall 4 of the borehole. Different kinds of sealing elements may be arranged on the outer face to increase the sealing ability of the sleeve towards the wall of the borehole.
  • the invention also relates to a well system 100 comprising the well tubular structure 3 and the annular barrier 1.
  • the well system 100 further comprises a tool 29 having an isolation means 30 isolating an isolated part 28 of the inside 23 of the tubular part outside the aperture 11 to pressurise the isolated part 28 of the inside 23 and thus the space 13 to expand the sleeve.
  • the isolation means 30 may be an inflatable elastomeric element or a metal packer.
  • the tool further comprises a pumping device 31 for pumping fluid from the inside of the tubular part being outside the isolated part 28 and into the isolated part 28 to expand the expandable sleeve 7.
  • the well system may also have several annular barriers 1.
  • the tool may also use coiled tubing for expanding the expandable sleeve of one annular barrier or two annular barriers at the same time.
  • a tool with coiled tubing can pressurise the fluid in the well tubular structure without having to isolate a section of the well tubular structure.
  • the tool may need to plug the well tubular structure further down the borehole for the two annular barriers to be operated.
  • the tool comprises a reservoir containing the pressurised fluid, e.g. when the fluid used for expanding the sleeve is cement, gas, or a two-component compound.
  • the space 13 may also be prefilled with some kind of fluid, such as a hardening agent, cement or the like.
  • An annular barrier may also be called a packer or similar expandable means.
  • the well tubular structure can be the production tubing or casing or a similar kind of tubing downhole in a well or a borehole.
  • the annular barrier can be used both in between the inner production tubing and an outer tubing in the borehole or between a tubing and the inner wall of the borehole.
  • a well may have several kinds of tubing and the annular barrier of the present invention can be mounted for use in all of them.
  • the valve may be any kind of valve capable of controlling flow, such as a ball valve, butterfly valve, choke valve, check valve or non-return valve, diaphragm valve, expansion valve, gate valve, globe valve, knife valve, needle valve, piston valve, pinch valve, or plug valve.

  • the expandable sleeve 3 of the annular barrier 1 When the expandable sleeve 3 of the annular barrier 1 is expanded, the diameter of the sleeve is expanded from its initial unexpanded diameter to a larger diameter.
