Method for running a continuous communication line through a packer
Techniques are provided for sealing a communication line within a device positioned in a wellbore. The communication line may be continuous and extends through a pass-through arranged generally longitudinally through the device. Swellable sealing material is positioned about and/or over the communication line which is placed in the pass-through of the device to form and maintain a secure seal once the device is submerged in a fluid that causes the swellable sealing material to expand.
1. A system for use in a well, comprising:
a packer having a pass-through region, the pass-through region comprising:
a generally axially oriented groove; and
a notch located within the groove;
a communication line extending through the pass-through region; and
a swellable material disposed along the communication line within the pass-through region.
2. The system as recited in claim 1 , wherein the groove is dove tail-shaped groove.
3. The system as recited in claim 1 , wherein the swellable material comprises a cover.
4. The system as recited in claim 3 , further comprising a stiffness member which is provided in the cover.
5. The system as recited in claim 3 , further comprising using an adhesive for sealing the cover.
6. The system as recited in claim 1 , wherein the packer comprises a packer mandrel along which the communication line extends, and the swellable material comprises sleeve segments wrapped around the communication line and the packer mandrel.
7. The system as recited in claim 6 , further comprising gripping members on the packer mandrel at a location where the sleeve segments are placed on the mandrel.
8. The system as recited in claim 6 , further comprising clamps for securing the sleeve segments on the mandrel.
9. The system as recited in claim 1 , wherein the packer comprises a sleeve having splits to receive the communication line.
10. The system as recited in claim 1 , wherein the communication line is continuous.
11. A method of providing communication in a wellbore, comprising:
providing a packer with a pass-through region comprising a groove and a notch defined at least partially within the groove;
routing a communication line through the pass-through region; and
sealing the communication line in the pass-through region with a swellable material that swells upon exposure to specific fluids, wherein the packer comprises:
a cover disposed about the swellable material; and
a stiffness member disposed within the cover and received into the notch.
12. The method as recited in claim 11 , wherein the pass-through region is formed along a mandrel of the packer.
13. The method as recited in claim 11 , wherein the pass-through region is formed as cut-outs in sleeve segments disposed about a packer mandrel.
14. The method as recited in claim 11 , wherein the swellable sealing material comprises a plurality of layers of swellable sealing material.
15. The method as recited in claim 11 , wherein the groove is generally axially oriented.
16. The method as recited in claim 11 , wherein the groove is generally axially oriented and dove tail-shaped.
17. The method as recited in claim 11 , wherein the communication line is continuous.
