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.
