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 influenced 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.

  • the compensation device may be arranged in the space between the expandable sleeve and the tubular part.
  • any leak of gas from the second chamber will result in gas accumulating inside the space defined by the expandable sleeve.
  • the gas By retaining any leaking gas, the gas will still have the ability to expand and thus equalise the pressure in the space to maintain the expandable sleeve in a sealing position and ensure the sealing capabilities of the annular barrier.
