DOWNHOLE TOOL WITH A DISSOLVABLE COMPONENT
First Claim
1. A method for fracturing a well, comprising:
- running downhole tool into a wellbore, the downhole tool comprising a ball seat including a dissolvable material and a protective layer that substantially prevents the dissolvable material from dissolving;
deploying an obstructing member into the wellbore, wherein the obstructing member is caught by the ball seat;
performing one or more fracturing operations while the obstructing member engages the ball seat, wherein performing the one or more fracturing operations comprises introducing an abrading fluid to the ball seat, and wherein the abrading fluid erodes at least a portion of the protective layer from the ball seat; and
after eroding the at least a portion of the protective layer, causing the dissolvable material of the ball seat to at least partially dissolve.

Abstract
A downhole tool and a method for fracturing a well, of which the method includes running downhole tool into a wellbore, the downhole tool including a ball seat including a dissolvable material and a protective layer that substantially prevents the dissolvable material from dissolving, and deploying an obstructing member into the wellbore. The obstructing member is caught by the ball seat. The method also includes performing one or more fracturing operations while the obstructing member engages the ball seat. Performing the one or more fracturing operations comprises introducing an abrading fluid to the ball seat, and the abrading fluid erodes at least a portion of the protective layer from the ball seat. The method also includes, after eroding the at least a portion of the protective layer, causing the dissolvable material of the ball seat to at least partially dissolve.

12. A downhole tool, comprising:
a dissolvable component comprising a dissolvable material and at least one protective outer layer at least partially enveloping the dissolvable material, wherein the at least one protective outer layer is configured to be eroded by an abrading fluid so as to allow introduction of the abrading fluid to the dissolvable material, wherein the dissolvable material dissolves in the presence of the abrading fluid. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A method of removing a component in a wellbore, the method comprising:
-
deploying the component into the wellbore, the component comprising a dissolvable material and a protective layer at least partially enveloping the dissolvable material, wherein the protective layer substantially prevents the dissolvable material from dissolving until the protective layer is at least partially removed by an abrading fluid; pumping the abrading fluid into the wellbore to remove at least a portion the protective layer of the component; and removing the component by dissolving the dissolvable material exposed by removing the at least a portion of the protective layer. - View Dependent Claims (21)
