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. 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;
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.

2. The method as claimed in claim 1 wherein the borehole operation is fracturing.

3. The method as claimed in claim 1 wherein the borehole operation is another setting operation.

4. A method for treating a borehole comprising running an anchor and seal system to depth, the system comprising 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; and
activating a setting arrangement to anchor and seal the anchor and seal system; and
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.

5. A borehole system comprising:
a tubular string; and
an anchor and seal system comprising:
a slip;
a cone in radially expanding communication with the slip; and
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 further including a plug seat.

6. The borehole system as claimed in claim 5 wherein the pusher includes a
radially outwardly bowing section.

7. The borehole as claimed in claim 6 wherein the pusher further includes a shortenable section.

8. The borehole system as claimed in claim 7 wherein the shortenable section is a cylindrical structure with a plurality of openings therein weakening an axially crush resistance thereof.

9. The borehole system as claimed in claim 7 wherein the shortenable section is a bellows shaped structure.
