Abstract

A penetrator for a Puncture Communication Tool includes a base; a body extending from the base and terminating at a tip; and a fluid bypass disposed in the body. Communicating a hydraulic chamber.

First claim

What is claimed is:

1. A Puncture and Communication Tool, comprising:
a ramp axially translatable within a tubular structure of a wellbore system;
a penetrator in operable communication with the ramp, the penetrator responsive to axial translation of the ramp to extend radially to breach a hydraulic fluid chamber of the tubular structure, the penetrator including:
a penetrator base;
a penetrator body extending from the base and terminating at a penetrator tip; and
a fluid bypass disposed in the penetrator body.

2. A puncture and communication tool as claimed in claim 1 wherein the fluid bypass is a narrowed neck of the body.

3. A puncture and communication tool as claimed in claim 1 wherein the body is hourglass shaped.

4. A puncture and communication tool as claimed in claim 1 wherein the fluid bypass is one or more recesses in the body.

5. A puncture and communication tool as claimed in claim 1 wherein the recess is positioned in the side of the body.

6. A puncture and communication tool as claimed in claim 1 wherein the recess extends to the tip.

7. A puncture and communication tool as claimed in claim 1 wherein the fluid bypass includes one or more passageways extending from the tip toward the base and intersecting one or more cross passageways extending from a side of the body.

8. A puncture and communication tool as claimed in claim 7 wherein the one or more passageways are one or more of coaxial and non-coaxial with the body.

9. A puncture and communication tool as claimed in claim 7 wherein the one or more cross passageways are orthogonally positioned relative to the body.

10. A puncture and communication tool as claimed in claim 1 wherein the fluid bypass is one or more through bores extending from the tip to the base.

11. A puncture and communication tool as claimed in claim 10 wherein the one or more through bores are one or more of coaxial and non-coaxial with the body.

12. A puncture and communication tool as claimed in claim 1 wherein one or more of the one or more through bores are parallel.

13. A method for communicating a hydraulic chamber with a puncture and communication tool as claimed in claim 1 comprising:
urging the penetrator through a wall of a hydraulic fluid chamber to penetrate into the hydraulic fluid chamber;
registering a pressure change in the hydraulic fluid chamber without retracting the penetrator.

14. A method as claimed in claim 13 wherein fluid flow causing the pressure change flows through a fluid bypass of the penetrator.

15. A method as claimed in claim 14 wherein the fluid bypass is one or more recesses.

16. A method as claimed in claim 13 wherein the fluid bypass is one or more through bores.

17. A method as claimed in claim 13 wherein the fluid bypass is one or more passageways and cross passageways.

18. A method as claimed in claim 13 wherein the fluid bypass is a narrower neck portion of a body of the penetrator.
