Definitions

  • the pressure envelope of a well is governed by the burst rating of the tubular and the well hardware etc. used within the well construction.
  • the expandable sleeve of an annular barrier may be expanded by increasing the pressure within the well, which is the most cost-efficient way of expanding the sleeve.
  • the burst rating of a well defines the maximum pressure that can be applied to the well to expand the sleeve, and it is desirable to minimise the expansion pressure required for expanding the sleeve in order to minimise the exposure of the well to the expansion pressure.
  • 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 is to be sealed off by the barrier, as the sealing properties are lost due to the collapse.
  • expansion means 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 annular barrier is capable of withstanding an outside pressure that is higher than the pressure in the well tubular structure without changing the pressure inside the well tubular structure since the diaphragm seals off the inside of the well tubular structure from the outside of the well tubular structure.
  • the diaphragm may be made from a deformable material.
  • the diaphragm may be made from an elastically/plastically deformable material.
  • the diaphragm may be cylindrical or corrugated.
  • the annular barrier may further comprise a connection part connecting the expandable sleeve to the tubular part.
  • the annular barrier may comprise a spacer which may be a part of the connection part, a part of the expandable sleeve or a separate part.
  • the annular barrier may further comprise a restriction element arranged on an outside of the expandable sleeve, restricting the sleeve from expanding freely.
  • the restriction element may be arranged on the inside of the sleeve.
  • the annular barrier may further comprise sealing elements arranged on an outside of the expandable sleeve for sealing against the inside wall of the borehole.
  • the diaphragm in an unexpanded state may substantially be shaped as a hollow cylinder.
  • the expandable sleeve may be capable of expanding to an at least 10% larger diameter, preferably an at least 15% larger diameter, more preferably an at least 30% larger diameter than that of an unexpanded sleeve, and it may have a wall thickness which is thinner than a length of the expandable sleeve, the thickness preferably being less than 25% of its length, more preferably less than 15% of its length, and even more preferably less than 10% of its length.
  • the expandable sleeve may have a varying thickness along its periphery and/or length.
  • more than one sealing member may be arranged between the slidable fastening means and the tubular part.
  • connection parts may be fixedly fastened to the tubular part or be part of the tubular part.
  • the sealing elements may have a sealing surface facing the inner side of the borehole.
  • the sealing surface may be serrated or be another kind of deformable surface.
  • the sealing elements may be made of polymers, elastomers, natural or synthetic rubber or silicone.
  • one of the two connection parts may be slidably connected with the tubular part and the other of the two connection parts may be fixedly connected with the tubular part.
  • the present invention may further relate to an annular barrier system comprising:
  • system may comprise a second annular barrier, wherein the inflow control section is arranged between the two annular barriers.
  • the present invention may further relate to a method of placing an annular barrier according to the invention in an annulus, the method comprising the steps of:
  • said method may comprise the step of opening the inflow control section.
  • the present invention may further relate to a zone isolation method for providing and maintaining zone isolation between a first zone and a second zone of the borehole, comprising the steps of:
  • the annular barrier 1 is used for a variety of purposes, all of which require that an expandable sleeve 3 of the annular barrier 1 is expanded so that the sleeve abuts the inside wall 101 of the borehole.
  • the annular barrier 1 comprises a tubular part 2 surrounded by the expandable sleeve 3.
  • the unexpanded sleeve has a cylindrical shape and at its ends it is connected with the tubular part.
  • the expandable sleeve 3 is expanded by letting pressurised fluid through an expansion opening 9 of the tubular part into an annular barrier space 6 between the expandable sleeve 3 and the tubular part 2.
  • the annular barrier 1 When the annular barrier 1 has been expanded using a pressurised fluid and abuts the inside of the borehole wall 101, the annular barrier provides a seal between a first zone 102 and a second zone 103 of the borehole.
  • the first zone 102 is on one side of the annular barrier 1 and the second zone 103 is on the other side of the annular barrier 1.
  • the annular barrier 1 When the pressure P expansion of the pressurised fluid is released in order to start production, the annular barrier 1 must be capable of withstanding a certain pressure P100 from the borehole 100 in order to prevent a collapse which would lead the barrier to become leaky.
  • the annular barrier 1 is used to seal off a production zone 400 (shown in Fig. 17 ), and a pressure P400 in the production zone might build up inside the production zone 400 when a fluid, such as oil, starts to enter the production zone 400 from the surrounding formation 200.
  • a fluid such as oil
  • the annular barrier 1 comprises a barrier compartment 7 which is in fluid communication with the borehole 100 through a first barrier opening 10, and since the barrier space 7 is in fluid communication with the first zone 102 of the borehole, the pressure P7 in the barrier compartment will build up as fluid flows from the first zone 102 and into the barrier compartment 7 (illustrated by an arrow), equalising the pressure in the barrier compartment 7 with the pressure in the first zone P102.
  • the diaphragms may abut each other, the outermost diaphragm being supported by an abutting element, such as the tubular part 2 or the expandable sleeve 3.
  • the deformation of a diaphragm material may be elastic, plastic or a combination thereof.
  • the deformation of both diaphragms and sleeves may also be referred to as expansion or expandable, since compared to the relaxed position, the material of the sleeve and diaphragms will be expanded during use.
  • the diaphragms and the sleeve may be connected with the tubular part 2 by means of a connection part 12.
  • the connection part may be connected with the sleeve and the diaphragms by means of welding or thread connections.
  • 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.
  • the expandable sleeve 3 has an outside diameter D and is capable of expanding to an at least 10% larger diameter, preferably an at least 15% larger diameter, more preferably an at least 30% larger diameter than that of an unexpanded sleeve.
  • the expandable sleeve 3 has a wall thickness t which is thinner than a length L of the expandable sleeve, the thickness preferably being less than 25% of the length, more preferably less than 15% of the length, and even more preferably less than 10% of the length.
  • a section 14 of the sleeve 3 In order to increase the thickness of a section 14 of the sleeve 3, additional material is applied onto an outer face 33 of the expandable sleeve, e.g. by adding welded material onto the outer face.
  • This section 14 is also referred to, in some embodiments, as a reinforcement ring 14.
  • the thickness of the section 14 of the sleeve 3 is increased by fastening a ring-shaped part onto the sleeve.
  • the ring-shaped part is the section 14 and is fastened to the inner surface by means of welding or a similar suitable fastening process.
  • a production zone 400 on one side of the annular barrier is a first zone 102 of the borehole with a first zone pressure P102, and on the other side of the annular barrier is the second zone 103 of the borehole, not forming part of the production zone 400.
  • the second zone pressure P103 suddenly increases substantially may be due to a gas leak further down the borehole 100, and the annular barrier 1 may suddenly experience an unexpected high pressure from the second zone pressure P103 even though the barrier was set up to seal a high production zone pressure P400.
  • the second diaphragm 5 is provided in the annular barrier 1.
  • the expansion compartment 6 is in fluid communication with an inside 302 of the well tubular structure 300 through an expansion opening 9, and the first barrier compartment 7 is in fluid communication with the first zone 102 of the borehole through a first barrier opening 10, and the second barrier compartment 8 is in fluid communication with the second zone 103 of the borehole through a second barrier opening 11.
  • the second zone pressure P103 builds up as shown in Fig. 7 , fluid will flow (illustrated by an arrow) into the second barrier compartment 8, forcing the first diaphragm to abut the expandable sleeve 3 and the second diaphragm 5 to abut the tubular part 2, thereby obtaining the second zone pressure P103 inside the annular barrier 1.
  • FIG. 7 shows the situation in which the second zone pressure P103 is the highest pressure, thereby forcing the second diaphragm 5 to abut the expandable sleeve 3 and the first diaphragm 4 to abut the tubular part 2.
  • Fig. 8 shows the situation in which the first zone pressure P102 is the highest, thereby forcing a fluid to enter the first barrier compartment 7 from the first zone 102 of the borehole 100 (illustrated by the arrow).
  • the first diaphragm 4 is forced towards the tubular part in that the first diaphragm 4 is forced to abut the second diaphragm 5 which is forced to abut the tubular part 2.
  • Fig. 9 shows the first and second diaphragms 4, 5 in intermediate positions, not abutting each other, nor abutting the expandable sleeve 3 or the tubular part 2.
  • a typical annular barrier has a length of 5 to 15 metres, and preferably 10 metres, to match standard well tubular parts and equipment for inserting well tubular parts into boreholes.
  • the difference between the diameter of an expanded and an unexpanded annular barrier may typically be less than 10 centimetres, and even less than 5 centimetres, which over a length of 5 to 15 metres applies very little stress to the diaphragm.
  • the diaphragms are shaped as hollow cylinders fastened at their ends to the connection parts and surrounding the tubular part which is surrounded by the expandable sleeve.
  • Figs. 10A and 10B show the annular barrier 1 having two diaphragms, and each diaphragm is shaped as a hollow cylinder fastened at its one end to a connection part and at its other end to the tubular part 2.
  • the tubular part 2 has an expansion opening 9 arranged in a middle part, and the ends of the diaphragms are connected with the tubular part 2 on opposite sides of the expansion opening 9 when seen in cross-section.
  • the diaphragms are welded to the tubular part, and at its other ends the diaphragms are connected with the connection parts by means of a thread connection.
  • the diaphragms may also be welded to the connection parts.
  • both the first barrier opening 10 and the second barrier opening 11 penetrate the connection part, the expansion sleeve 3 and the diaphragm providing fluid communication between the first zone 102 and the first barrier compartment and the second zone 103 and the second barrier compartment, respectively.
  • the first barrier opening 10 and the second barrier opening 11 penetrate only the connection part. In this way, the expandable sleeve 3 and the diaphragms are not penetrated, resulting in a more simple design.
  • the diaphragms in Figs. 10A and 10B may also be manufactured from one cylinder fastened at its ends to the connection parts and at a middle part welded to the tubular part, and subsequently, the expansion openings are provided therein through the tubular part.
  • the annular barrier of Fig. 11 also has two diaphragms; a first diaphragm connected at its ends to the connection part and a second diaphragm which in its one end is connected with one connection part and in its other end is connected with the tubular part 2 near the expansion opening 9.
  • the expansion opening 9 is provided in the tubular part 2 near the connection part in which only the first diaphragm is fastened. Thus, the expansion opening 9 is not arranged in the middle part of the tubular as in Figs. 10A and 10B .
  • Figs. 10A and 10B show a first barrier opening 10 and a second barrier opening 11
  • the barrier openings may be replaced by a non-sealing connection between the connection part and the tubular part.
  • the first barrier connection may be replaced in the same way by a leaky connection between the connection part and the tubular part.
  • the first diaphragm shown in Fig. 11 allows that a completely tight sealing connection is not needed between the connection part 12 and the tubular part 2 at the end of the annular barrier 1 where the first diaphragm 4 is connected to the connection part.
  • the first diaphragm arranged in this way results in this connection part possibly being the sliding end of the annular barrier, thereby complying with the need for a movable end due to the shortening of the sleeve during expansion while still providing a seal between the outside pressure and the inside of the well tubular structure, and then the other end can be fixedly connected to the tubular part 2.
  • the first diaphragm of Fig. 11 has the ability to expand substantially the entire volume of the annular barrier 1, equivalently to if it was connected with both connection parts due to the fact that its connection with the tubular part 2 can be arranged so close to the connection part in which only the second diaphragm is connected that the first diaphragm can be expanded in substantially the entire volume of the annular barrier 1.
  • the projecting part 13 has the purpose of restricting the expansion of the expandable sleeve 3 so that the curvature of the expandable sleeve 3 when expanded is more S-shaped when seen in the cross-sectional view along the longitudinal extension of the sleeve. It is hereby obtained that the expandable sleeve 3 does not fracture during expansion and that the cross-sectional profile of the expandable sleeve 3 is capable of withstanding a higher collapse pressure than a known annular barrier. Thus, the expandable sleeve 3 is more restricted in expanding at the first point than at the second point. Furthermore, due to the fact that the projecting part 13 may be made from a less flexible metal alloy and tapers from the connection towards the second point, the expandable sleeve 3 is less restricted in expanding along with the decreasing thickness of the projecting part.
  • the first barrier opening 10 may also be arranged directly in the expandable sleeve 3, as shown in Fig. 13 , resulting in a very simple design which is easy to manufacture and implement in existing manufacturing procedures.
  • the diaphragms, the sleeve, the connection part 12 and the tubular part 2 may be welded as best suited in a specific annular barrier.
  • the diaphragms and sleeves may be welded if the connection part is slidably connected to the tubular part, or they may be welded to the tubular part if the connection part is fixedly connected to the tubular part etc.
  • the expandable sleeve and the diaphragm/-s may also be fastened directly to the tubular part without use of connection parts, as shown in Fig. 14 .
  • the expandable sleeve of the annular barrier may have one end fastened by means of a connection part and the other end welded directly to the tubular part together with a diaphragm.
  • both ends can be fixed by welding or both ends can be sliding along the tubular part 2.
  • Fig. 15 also shows the possibility of using a valve 19 instead of the barrier opening 10.
  • the expansion opening 9, the first barrier opening 10 and/or the second barrier opening 11 may in some embodiments be replaced by a valve to control the flow from the borehole into the barrier compartments or to control the flow from the inside of the well tubular structure 300 and into the expansion compartment 6. Also, the flow direction may be restricted using one-way valves.
  • additional material may be applied onto an inner or outer face of the sleeve, e.g. by adding welded material onto the inner face.
  • sealing elements 15 are arranged opposite the sections of the sleeve having an increased thickness.
  • the sealing elements 15 fill up the gap occurring during expansion.
  • the sealing elements 15 have a tapering or triangular cross-sectional shape.
  • annular barrier When the annular barrier is installed, it forms part of a well tubular structure, as shown in Fig. 17 , providing an annular barrier system 500.
  • the system comprises two annular barriers sealing a production zone 400.
  • the barriers are arranged in a horizontal part of the well and are seen in their expanded condition.
  • An inner ring may also be arranged between the expandable sleeve 3 and the tubular part 2 and may be welded to the connection part 12.
  • An expansion tool may be used to expand the annular barrier and may comprise an isolation device for isolating a first section outside the passage or valve between an outside wall of the tool and the inside wall of the well tubular structure.
  • the pressurised fluid is obtained by increasing the pressure of the fluid in the isolation device.
  • the tool may also use coiled tubing for expanding the expandable sleeve 3 of an annular barrier 1 or of 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 from the two annular barriers or barriers 1 to be operated.
  • the annular barrier system of the present invention may also employ a drill pipe or a wireline tool to expand the sleeve.
  • the tool comprises a reservoir containing the pressurised fluid, e.g. when the fluid used for expanding the sleeve 3 is cement, gas or a two-component compound.
  • An annular barrier 1 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 1 can be used both 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 1 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.
