Method and apparatus for releasing a coiled tubing internal conduit from a bottom hole assembly

1. A system to selectively connect an internal line within coiled tubing to a bottom hole assembly connected to the coiled tubing, the system comprising:

an anchor assembly connected to the internal line, the anchor assembly being selectively connected to the bottom hole assembly;

a piston movable between a first position and a second position, the piston being selectively connected to the anchor assembly; and

at least one shearable device configured to retain the piston in the first position;

wherein at a predetermined pressure the piston is adapted to shear the shearable device and move to the second position;

wherein the movement of the piston releases a portion of the anchor assembly and the internal line from the bottom hole assembly.

2. The system of claim 1 , wherein the internal line is a conduit, wire, capillary tube, cable, hydraulic line, fiber optic, or solid rod.

3. The system of claim 1 further comprising a seat adapted to retain an object to prevent flow through the bottom hole assembly.

4. The system of claim 3 wherein the seat is a ball seat adapted to retain a ball pumped down the coiled tubing.

5. The system of claim 4 wherein the ball seat is located on a portion of the bottom hole assembly.

6. The system of claim 1 further comprising the internal line provides communication between the bottom hole assembly and a surface.

7. The system of claim 6 , wherein the communication is bidirectional.

8. A method of releasing an internal line within coiled tubing from a bottom hole assembly connected to the coiled tubing, the method comprising:

pumping an object down the coiled tubing;

seating the object on a seat portion of the bottom hole assembly, wherein the seated object prevents fluid flow through the bottom hole assembly;

pumping fluid down the coiled tubing to increase pressure within the coiled tubing;

releasing the internal line from the bottom hole assembly at a predetermined pressure within the coiled tubing.

9. The method of claim 8 wherein the internal line is a conduit, wire, capillary tube, cable, hydraulic line, fiber optic cable, or solid rod.

10. The method of claim 8 further comprising removing the internal line from the coiled tubing.

11. The method of claim 8 wherein the object pumped down the coiled tubing is a ball.

12. The method of claim 8 wherein releasing the internal line further comprises the predetermined pressure moving a piston of an anchor assembly releasing the anchor assembly from the bottom hole assembly, wherein the anchor assembly is connected to the internal line.

13. The method of claim 12 wherein moving the piston of the anchor assembly further comprises shearing a shearable device releasing the piston from an initial position.

14. The method of claim 8 further comprising the internal line provides communication between the bottom hole assembly and a surface.

15. The method of claim 14 , wherein the communication is bidirectional.
