Abstract

A setting assembly including a settable member. A housing including a chamber and a setting material disposed in the chamber and having a first phase of matter and a second phase of matter. The setting material occupying a greater volume in the second phase than in the first phase. The setting material arranged to exert a setting force on the settable member during transition of the setting material from the first phase to the second phase. Also included is a method of setting a settable member.

First claim

The invention claimed is:

1. A setting assembly comprising:
a settable member;
a housing including a chamber;
a piston including a piston head movably disposed within the chamber, and a piston rod connected to the piston head and extended exteriorly of the chamber, the piston head dividing the chamber into a first area and a second area; and,
a setting material disposed in the second area of the chamber and restricted from the first area of the chamber by the piston head, the setting material having a first phase of matter and a second phase of matter, the setting material occupying a greater volume in the second phase than in the first phase, the setting material arranged to exert a force on the piston head to move the piston head within the chamber during transition of the setting material from the first phase to the second phase;
wherein movement of the piston rod effects setting and unsetting of the settable member.

2. The setting assembly of claim 1 wherein the first phase of the setting material is solid and the second phase is liquid.

3. The setting assembly of claim 1 wherein the settable member is a compression packer.

4. The setting assembly of claim 1 wherein the housing is arranged on a wireline device.

5. The setting assembly of claim 1 wherein the setting material is a paraffin material.

6. The setting assembly of claim 1 further comprising a heat source to transition the setting material from the first phase to the second phase.

7. The setting assembly of claim 6 wherein the heat source is steam from a steam assisted gravity drainage system.

8. The setting assembly of claim 6 wherein the heat source is a heating element adjacent the housing, the heating element selectively controlled by a control line.

9. The setting assembly of claim 1 , wherein the piston rod includes a first end and an opposite second end, the first end connected to the piston head and the second end including an engagement feature.

10. A setting assembly of comprising;
a settable member;
a housing including a chamber;
a setting material disposed in the chamber and having a first phase of matter and a second phase of matter, the setting material occupying a greater volume in the second phase than in the first phase, the setting material arranged to exert a setting force on the settable member during transition of the setting material from the first phase to the second phase; and,
a movable piston head within the chamber and dividing the chamber into a first area and a second area, the setting material disposed in the second area and restricted from the first area by the piston head, and a piston rod extending from the piston head and exteriorly of the chamber to effect setting and unsetting of the settable member, wherein transition of the setting material from the first phase to the second phase moves the piston head.

11. A method of setting a settable member, the method comprising:
enclosing a phase changeable setting material within a chamber of a housing in a solid state, a piston head of a piston dividing the chamber into a first area and a second area, the setting material disposed in the second area and restricted from the first area by the piston head;
heating the setting material to melt the setting material to a liquid state to expand a volume of the setting material;
harnessing the expansion of the setting material as a setting force to move the piston head within the chamber; and,
utilizing the piston rod of the piston to engage with and set the settable member.

12. The method of claim 11 wherein heating the setting material includes injecting steam into a steam assisted gravity drainage system.

13. A downhole system employable within a borehole, the downhole system including:
a tubular structure having a flow path; and,
the setting assembly of claim 1 , wherein the chamber is disposed exteriorly of the flow path.
