Abstract

An object removal enhancement arrangement including a seat, a volume movable with the seat, the volume being protected in a first condition of the seat and unprotected in a second condition of the seat, and a material disposed within or as a part of the volume, the material degradative of an object.

First claim

What is claimed is:

1. An object removal enhancement arrangement comprising:
a seat;
a volume movable with the seat, the volume being protected in a first condition of the seat and unprotected in a second condition of the seat; and
a material disposed within or as a part of the volume in the first condition and movable with the seat, the material degradative of an object.

2. The arrangement as claimed in claim 1 wherein the volume is in a recess in the seat.

3. The arrangement as claimed in claim 1 wherein the volume is of a component other than the seat while remaining movable with the seat.

4. The arrangement as claimed in claim 1 wherein the volume is protected by a closure member.

5. The arrangement as claimed in claim 4 wherein the closure member is a rupture member.

6. The arrangement as claimed in claim 4 wherein the closure member includes a seal.

7. The arrangement as claimed in claim 4 wherein the closure member is a sleeve.

8. The arrangement as claimed in claim 1 wherein the material is an acid.

9. The arrangement as claimed in claim 1 wherein the material is polyglycolic acid.

10. The arrangement as claimed in claim 1 wherein the material is polylactic acid.

11. A resource recovery system comprising:
a tubular string disposed in a formation;
a seat disposed in the tubular string;
a volume moveable with the seat, the volume being protected in a first condition of the seat and unprotected in a second condition of the seat; and
a material disposed within or as a part of the volume in the first condition and movable with the seta, the material degradative of an object.

12. A method for enhancing response time for degrading degradable objects in a system comprising:
landing a first object on a first seat;
pressuring against the first object;
landing a second object on a second seat uphole of the first object;
exposing a material moveable with the second seat to an environment between the first seat and the second seat, the material being degradative to an object.

13. The method as claimed in claim 12 wherein the pressuring against the first object includes fracturing a formation.

14. The method as claimed in claim 12 wherein the exposing includes shifting the second seat.

15. The method as claimed in claim 12 wherein the exposing includes rupturing a closure member.

16. The method as claimed in claim 12 wherein the exposing includes moving a sleeve disposed about the second seat.

17. The method as claimed in claim 12 wherein exposing the material includes migrating the material to the first object.

18. The method as claimed in claim 12 wherein exposing the material includes degrading the first object.
