Furthermore, the present invention relates to a completion method and a production method for producing hydrocarbon-containing fluid from a reservoir into a well tubular structure.
  • the screens are designed so that mounting of the completion system at the rig is very complicated as the commonly used tools for connecting the well tubular structure cannot be used. There is therefore a need for an alternative so that the well tubular structure of the completion can easily be mounted by the known tools at the rig.
  • a completion system for connecting several screens into a well tubular structure mounted from base pipe sections comprising:
  • the well tubular structure may have an opening for letting the fluid into the well tubular structure.
  • one of the base sections may have an opening for letting the fluid into the well tubular structure.

  • the internal thread of the tubular member connector may at least partly engage the external thread of the screen element fixation part.
  • tubular member may not be directly connected to the assembly connection part.
  • tubular member may have a distance to the outer face of the assembly connection part.
  • the assembly connection part may have an outer diameter which is larger than the outer diameter of the base pipe section.

  • the flow section may be mounted between two screen assemblies.
  • the flow section may have a first end mounted to one screen assembly and a second end mounted to another screen assembly.
  • Said flow section may have an opening for letting fluid from the screen assemblies into the well tubular structure.
  • the completion system as described above may further comprise a second tubular member arranged opposite the flow section so that fluid flowing in through the tubular screen element of one of the screen assemblies flows on the outside of the base pipe section and in through the flow section, or vice versa.
  • completion system as described above may further comprise at least one annular barrier assembly comprising:
  • the completion system may comprise a plurality of screen assemblies.

  • the first tubular member connector having the left hand thread may be arranged closest to the top of the well in relation to the tubular member which is fastened to the second tubular member connector, and the second tubular member connector having the right hand thread may thus be arranged on the other side of the tubular member, and as the well tubular structure is rotated while it is run in hole, the first and second tubular member connectors may then be further tightened instead of being unscrewed.
  • the assembly connection part may have a solid massive wall.
  • a solid massive wall is meant that the wall has no channels or openings.
  • tubular member may comprise a screen.
  • tubular member may comprise at least one radially extending projection part.
  • the projection part may be a dimple.
  • tubular member may be solid or massive, meaning that it has no openings or channels.

  • the base pipe sections 3 can be mounted by assembly connection parts 8 being standard casing collars or casing couplings.
  • assembly connection parts 8 do not have to be complicated, specially designed couplings which have to undergo separate qualifications, and such specially designed couplings may also increase the overall costs associated with the completion system 1 and thus the well.

  • the assembly connection part 8 has a solid massive wall and the tubular member 11 is solid or massive, and the wall of the assembly connection part and tubular member is thus unperforated, meaning that the assembly connection part and the tubular member have no openings or channels.
  • the thread of the first tubular member connector 12a is a left hand thread and the thread of the second tubular member connector 12b is a right hand thread.
  • the first tubular member connector 12a having the left hand thread is arranged closest to the top of the well in relation to the tubular member 11 which is fastened to the second tubular member connector 12b, and the second tubular member connector 12b having the right hand thread is thus arranged on the other side of the tubular member.
  • the well tubular structure is often rotated clockwise, and the first and second tubular member connectors 12, 12a, 12b are then further tightened instead of being unscrewed when run in hole. In situations in which the tubluar sturcture has to be rotated anti-clockwise, the arrangement of the left handed and right handed connectors would be swapped.

  • the centralisers 25 are arranged close to the screen assemblies to protect them while the well tubular structure is run in hole.
  • the centralisers ensure a certain distance from the well tubular structure to the wall of the borehole, so that projections or ledges in the borehole wall do not harm the function of the screen assemblies while the screen assemblies pass down the borehole.
  • the annular barrier assembly is shown in its unexpanded position and is arranged between the centraliser and one of the screen assemblies.
  • the tubular member connector 12 could also be a centraliser, besides functioning as a tubular member connector.
