Abstract:
1. A supercapacitor device configured to be disposed in a wellbore through a fluid-producing formation, the supercapacitor device comprising: a body configured to be disposed in the wellbore; a supercapacitor disposed in the body and configured to store energy; at least two terminals disposed at least partially outside the body, the at least two terminals configured to be electrically connected with the supercapacitor, wherein an electrical connection between the supercapacitor and the at least two terminals is adapted to cause the energy to be discharged from the supercapacitor in response to a conductive material providing an electrical path between the at least two terminals; and an actuation mechanism configured to selectively prevent discharge of the energy from the supercapacitor when the supercapacitor device is deployed into the wellbore, wherein the actuation mechanism comprises at least one compressible actuation mechanism, wherein the at least one compressible actuation mechanism is adapted to apply a force to at least one terminal in a direction away from the body, the force causing the at least one terminal to be electrically disconnected from the supercapacitor.
