Abstract

A tool for use in a wellbore that includes a mandrel having an interior and an exterior with a plurality of keyed ring members along the exterior of the mandrel having an external line that runs the length of the tool. The tool may include a packing element positioned between at least a first keyed ring member and a keyed second ring member. A line is run between the exterior of the mandrel and an interior of the packing element, through an inner bore of the first ring, and through an inner bore of the second ring. Key members may be removed from the ring members to permit the insertion of the line through the packer system. The key members may be removed to removal of a ring component from the packer system. The key members and ring component enable a tool to be constructed onsite at a wellbore.

First claim

What is claimed is:

1. A packer system for use in a wellbore comprising:
a mandrel having an interior and an exterior;
a packer assembly including a packing element positioned between a first ring and a second ring, the packer assembly being configured to slide onto the exterior of the mandrel, wherein the first ring includes a first gap along the first ring between a first end and a second end;
a line configured to run between the exterior of the mandrel and an interior of the packing element, through an inner bore of the first ring, and through an inner bore of the second ring; and
a first key member, wherein the first gap is configured to receive the first key member, wherein removal of the first key member from the first gap enables the line to pass from the inner bore of the first ring to an exterior of the first ring.

2. The packer system of claim 1 , wherein the packer assembly is configured to slide onto the exterior of the mandrel onsite at the wellbore.

3. The packer system of claim 1 , wherein insertion of the first key member into the first gap selectively interlocks the first key member with the first and second ends of the first ring.

4. The packer system of claim 1 , wherein the first key member comprises a metal, a polymer, a thermoplastic, an elastomeric, or a combination thereof.

5. The packer system of claim 1 , further comprising a second key member and a second gap configured to receive the second key member, the second gap being along the second ring between a first end and a second end, and wherein the insertion of the second key member into the second gap selectively interlocks the second key member with the first and second ends of the second ring.

6. The packer system of claim 5 , wherein the first key has a first cross-sectional geometry and the second key has a second cross-sectional geometry, the second geometry differing from the first geometry.

7. The packer system of claim 5 , wherein removal of the second key member from the second gap enables the line to pass from the inner bore of the second ring to an exterior of the second ring.

8. A method of providing a packer system comprising:
providing a packer assembly on a mandrel, the packer assembly including a first ring, a packing element, and a second ring, wherein the packing element is positioned between the first and second rings;
installing a line between an exterior of the mandrel and an inner surface of the packing element, through an inner bore of the first ring, and through an inner bore of the second;
wherein the line may be installed through a first gap along the first ring and a second gap along the second ring;
inserting a first key member into the first gap and inserting a second key member into the second gap after installing the line; and
removing the first key member from the first gap and removing the first ring from the packer assembly, wherein the line passes from the inner bore of the first ring through the first gap.

9. The method of claim 8 , wherein the packer assembly is provided on the mandrel onsite at a wellbore location.

10. The method of claim 8 , wherein the first key member is inserted in a longitudinal direction with respect to a longitudinal centerline of the mandrel.

11. The method of claim 8 , wherein the first key member is inserted in a transverse direction with respect to a longitudinal centerline of the mandrel.

12. The method of claim 8 , wherein the first key member interlocks with the first ring and wherein the second key member interlocks with the second ring.

13. A packer system for use in a wellbore comprising:
a mandrel having an interior and an exterior;
a packer assembly including a packing element positioned between a first ring and a second ring, the packer assembly being configured to slide onto the exterior of the mandrel, wherein the first ring includes a first gap along the first ring between a first end and a second end;
a line configured to run between the exterior of the mandrel and an interior of the packing element, through an inner bore of the first ring, and through an inner bore of the second ring;
a first key member, wherein the first gap is configured to receive the first key member; and
a second key member and a second gap along the first ring, the second gap between a third end and a fourth end and the second gap being configured to receive the second key member, wherein the insertion of the second key member into the second gap selectively interlocks the second key member with the third and fourth ends of the first ring.

14. The packer system of claim 13 , wherein the first gap and the second gap are approximately 180 degrees apart along the first ring.

15. The packer system of claim 13 , wherein the removal of the first key member from the first gap and the removal of the second key member from the second gap separates the first ring into two separate components.
