Downhole supercapacitor device

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 and connected by a conductive material, 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 through an electrical path provided by the conductive material 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 conductive material is adapted to melt in response to the supercapacitor being discharged and to couple an object in the wellbore to the supercapacitor device and further comprising a retrieval mechanism configured to retrieve the supercapacitor device coupled to the object via the conductive material.
