Title: APPARATUS AND METHOD FOR GALVANICALLY REMOVING FROM OR DEPOSITING ONTO A DEVICE A METALLIC MATERIAL DOWNHOLE
Abstract:
In one aspect, a method of performing a wellbore operation is disclosed that in one embodiment may include: deploying a device in the wellbore containing a conductive fluid, wherein the device is configured to disintegrate upon application of electrical current thereto; and applying current to the device in the wellbore using a tool to controllably disintegrate the device. In another aspect, an apparatus for use downhole is provided that in one embodiment may include a device placed at a selected location in a wellbore, wherein the device is made from a material that disintegrates when electric current is induced in to device and a tool placed proximate to the device configured to induce electric current into the device to cause the device to disintegrate.
