Abstract

A method of deploying a tool in a wellbore includes installing a tool body at an upper end of a tubular string extending from a wellbore, the body having at least one control line groove formed on its outer surface with the at least one control line housed therein. The method also includes providing an assembly strung on the at least one control line. The assembly includes an element with at least one ring on each end thereof; at least one ring on each end of the element; a locking ring at an upper end of the assembly. The method further includes installing the assembly over the body to house the at least one control line between the body and the assembly.

First claim

The invention claimed is:

1. A method of deploying a tool in a wellbore, comprising:
installing a tool at an upper end of a tubular string extending from a wellbore, wherein the tool comprises:
a body having an outer surface with at least one longitudinal groove formed therein; and
an insert disposed in each of the at least one longitudinal groove, the insert having at least one control line groove formed on an outer surface for housing at least one control line, the at least one control line housed therein;

providing an assembly, the assembly strung on the at least one control line and including:
an element having at least one longitudinal groove formed in an inner surface, wherein the at least one longitudinal groove of the element aligns with the at least one control line groove of the insert; and
at least one ring on each end of the element; and

installing the assembly over the body, the at least one control line housed between the body and the assembly.

2. The method of claim 1 , further comprising providing a lower locking ring at a lower end of the body and an upper locking ring at an upper end of the body, whereby the element and rings are retained on the body between the lock rings.

3. The method of claim 2 , wherein the at least one ring includes a metal ring and a deformable ring at each end of the element.

4. The method of claim 3 , wherein the at least one ring further includes a pair of castellated rings at each end of the element.

5. The method of claim 2 , further comprising running the tool into the wellbore on the tubular string.

6. The method of claim 5 , further comprising installing a second tool comprising a body, assembly and upper locking ring at a second location along the tubular string.

7. The method of claim 6 , further including installing a fracking tool in the tubular string between the two tools, the fracking tool constructed and arranged to treat a zone defined as an area of the well between the tools.

8. The method of claim 7 , further including setting the tools in the wellbore, thereby causing the element of each tool to be compressed and expanded outwards in the direction of a wall of the wellbore, thereby isolating the zone.

9. The method of claim 8 , further including treating the zone by fracking.

10. The method of claim 9 , further including collecting and transmitting data from the zone via the at least one control line.

11. The method of claim 10 , wherein the data includes at least one of pressure, temperature, and flow rate of fluid in the zone.

12. The method of claim 5 , further comprising setting the tool in the wellbore at a predetermined location, thereby causing the element to be compressed and expanded outwards in the direction of a wall of the wellbore.

13. A downhole tool, comprising:
a body having an outer surface with a longitudinal groove formed therein;
an insert disposed in the longitudinal groove, wherein the insert includes a control line groove constructed and arranged to house a portion of a control line;
an element, the element having a longitudinal groove in an inside surface thereof, the groove constructed and arranged to house a portion of the control line when the element is installed over the body;
a lower locking ring at a lower end of the element and an upper locking ring at an upper end of the element; and
at least one ring at each end of the element, the at least one ring housed between the locking rings.

14. The tool of claim 13 , wherein the at least one ring is constructed and arranged to deform when the tool is set.

15. The tool of claim 13 , wherein the element is selectively compressed in a wellbore to expand outwards in the direction of a wall of the wellbore.

16. A downhole tool, comprising:
a tubular body having a longitudinal groove formed on an outer surface;
a linear insert disposed in the longitudinal groove on the tubular body, wherein the linear insert includes a control line groove extending a length of the control line groove;
a cylindrical sealing element disposed around the tubular body, wherein the sealing element has a longitudinal groove formed on an inner surface, and the longitudinal groove of the sealing element is aligned with the control line groove of the linear insert to house a control line therebetween;
a lower locking ring configured to couple to the tubular body at a lower end of the sealing element; and
an upper locking ring configured to couple to the tubular body on at an upper end of the sealing element.

17. The downhole tool of claim 16 , wherein the linear insert is made of an elastomeric material.

18. The downhole tool of claim 17 , wherein the sealing element is made of a resilient elastomeric material.

19. The downhole tool of claim 16 , wherein each of the upper locking ring and lower locking ring includes a slot to permit the control line to extend along an outer surface of the locking ring to an inner surface of the locking ring.

20. The downhole tool of claim 16 , further comprising:
an upper metal ring;
an upper deformable ring, wherein the upper metal ring and the upper deformable ring are disposed on the tubular body between the upper end of the sealing element and the upper locking ring;
a lower metal ring; and
a lower deformable ring, wherein the lower metal ring and the lower deformable ring are disposed on the tubular body between the lower end of the sealing element and the lower locking ring.
