Abstract
Sealing devices such as packers comprise an expandable sealing element that is inflated and/or deflated by an electrically-activated pump disposed in a wellbore so that the sealing element can be set and retrieved from the wellbore. The pump is disposed downhole in close proximity to the expandable sealing element and is electronically associated with a surface processing unit located at the surface of the wellbore. In certain embodiments, an electric motor electronically associated with the surface processing unit drives the pump to flow a fluid into a chamber of the expandable sealing element to inflate the expandable sealing element and pumps the fluid out of the chamber of the expandable sealing element to deflate the expandable sealing element. Multiple sealing elements can be disposed on a tool or work string and all can be addressable and individually and separately controlled by the surface processing unit.
