Abstract
Abstract A technique for providing auxiliary conduits in multi-trip completions is disclosed. The technique has particular applicability to liner mounted screens which are to be gravel packed. In the preferred embodiment, a protective shroud is run with the gravel pack screens with the auxiliary conduits disposed in between. The auxiliary conduits terminate in a quick connection at a liner top packer. The gravel packing equipment can optionally be secured in a flow relationship to the auxiliary conduits so as to control the gravel packing operation. Subsequent to the removal of the specialized equipment, the production tubing can be run with an auxiliary conduit or conduits for connection down hole to the auxiliary conduits coming from the liner top packer for a sealing connection. Thereafter, during production various data on the well can be obtained in real time despite the multiple trips necessary to accomplish completion. The various completion and/or production activities can also be accomplished using the auxiliary conduits such as actuation of down hole flow control devices, chemical injection, pressure measurement, distributed temperature sensing through fiber optics, as well as other down hole parameters.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
109 words
1 . A method of completion of a well, comprising: attaching at least one auxiliary conduit or cable to a downhole assembly; providing an upper connection to said conduit or cable; running in said downhole assembly with said cable or conduit to a desired location in the well; tagging into said downhole assembly and said upper connection of said conduit or cable downhole on at least one subsequent trip into the well with a tubular having at least one auxiliary cable or conduit extending along its length from the surface; communicating through said auxiliary cable or conduit between the surface and the downhole assembly on a real time basis.
Claim 2
Dependent Claim
109 words
1 . A method of completion of a well, comprising: attaching at least one auxiliary conduit or cable to a downhole assembly; providing an upper connection to said conduit or cable; running in said downhole assembly with said cable or conduit to a desired location in the well; tagging into said downhole assembly and said upper connection of said conduit or cable downhole on at least one subsequent trip into the well with a tubular having at least one auxiliary cable or conduit extending along its length from the surface; communicating through said auxiliary cable or conduit between the surface and the downhole assembly on a real time basis.
Claim 3
Dependent Claim
67 words
2 . The method of claim 1 , further comprising: tagging into said downhole assembly on a subsequent trip with production tubing having at least one auxiliary cable or conduit which is also connectable to said upper connection of said cable or conduit on the downhole assembly; communicating during production through auxiliary cable or conduit between the surface and the downhole assembly on a real time basis.
Claim 4
Dependent Claim
37 words
3 . The method of claim 1 , further comprising: plugging said upper connection during said running in of the downhole assembly and auxiliary cable or conduit; unplugging said upper connection with another trip into the well.
Claim 5
Dependent Claim
16 words
4 . The method of claim 1 , further comprising: performing said tagging in without rotation.
Claim 6
Dependent Claim
19 words
5 . The method of claim 4 , further comprising: selectively locking said connections resulting from said tagging in.
Claim 7
Dependent Claim
38 words
6 . The method of claim 1 , further comprising: configuring said auxiliary conduit or cable adjacent said downhole assembly in a manor which permits monitoring or altering adjacent well conditions or the functioning of the downhole assembly.
Claim 8
Dependent Claim
33 words
7 . The method of claim 6 , further comprising: using a gravel pack screen and packer for said downhole assembly extending said cable or conduit through said packer to said upper connection.
Claim 9
Dependent Claim
19 words
8 . The method of claim 7 , further comprising: delivering gravel through said at least one of conduits.
Claim 10
Dependent Claim
16 words
9 . The method of claim 1 , further comprising: using fiber optic as said cable.
Claim 11
Dependent Claim
21 words
10 . The method of claim 9 , further comprising: using said fiber optic to measure strain on said downhole assembly.
Claim 12
Dependent Claim
26 words
11 . The method of claim 1 , further comprising: using said auxiliary cable or conduit to operate at least a portion of said downhole assembly.
Claim 13
Dependent Claim
26 words
12 . The method of claim 7 , further comprising: running in an outerjacket, assembled over said cable or conduit, together with said screen and packer.
Claim 14
Dependent Claim
33 words
13 . The method of claim 7 , further comprising: running in at least one fiber optic cable on said screen; using said fiber optic to determine fluid conditions flowing to said screen.
Claim 15
Dependent Claim
27 words
14 . The method of claim 13 , further comprising: providing a winding inlet channel for inflow to said screen; locating said fiber optic in said channel.
Claim 16
Dependent Claim
69 words
15 . The method of claim 1 , further comprising: running said auxiliary conduit or cable in a U-shaped path so as to provide a pair of upper connections; extending said U-shaped path to the surface as a result of said tagging, an auxiliary conductor or cable attached to a tubular run in from the surface, into each of said upper connections on a subsequent trip into the wellbore.
Claim 17
Dependent Claim
