Abstract

An anchor and seal system including a slip, a cone in radially expanding communication with the slip, an element in loadable communication with the cone, and a pusher configured to radially displace the element to reside on an element retention surface of the pusher. A method for treating a borehole including running an anchor and seal system above to depth, activating a setting arrangement to anchor and seal the anchor and seal system.

First claim

What is claimed is:

1. An anchor and seal system comprising:
a slip;
a cone in radially expanding communication with the slip;
an element in axially loadable but not radially loadable communication with the cone; and
a pusher configured to radially displace the element to reside on an element retention surface of the pusher wherein the pusher further includes a plug seat.

2. An anchor and seal system comprising:
a slip;
a cone in radially expanding communication with the slip;
an element in loadable communication with the cone;
a backup between the cone and the element; and
a pusher configured to radially displace the element to reside on an element retention surface of the pusher which presents the element for loaded contact between the pusher and a separate tubular when the element is disposed on the element retention surface wherein the pusher includes a plug seat.

3. The system as claimed in claim 2 wherein the element retention surface is textured.

4. The system as claimed in claim 2 wherein the element is polymeric.

5. The system as claimed in claim 2 wherein the element is elastomeric.

6. The system as claimed in claim 2 further comprising the backup ring being at only one axial end of the element.

7. The system as claimed in claim 2 wherein the pusher includes an angled pusher surface.

8. The system as claimed in claim 2 wherein the element includes an element chamfer surface.

9. The system as claimed in claim 2 wherein the cone includes a chamfer.

10. The system as claimed in claim 2 further comprising a backup ring at only one axial end of the element.

11. A method for treating a borehole comprising:
running an anchor and seal system to depth, the system comprising
a slip;
a cone in radially expanding communication with the slip;
an element in loadable communication with the cone; and
a pusher configured to radially displace the element to reside on an element retention surface of the pusher, the pusher prior to setting lacking direct contact with the cone and then upon setting having direct contact with the cone;

activating a setting arrangement to anchor and seal the anchor and seal system;
deploying a plug to land in a seat of the anchor and seal system; and
pressuring the borehole against the plug in the seat to effect a borehole operation.

12. The method as claimed in claim 11 wherein the borehole operation is fracturing.

13. The method as claimed in claim 11 wherein the borehole operation is another setting operation.
