Abstract
The present invention is directed to processes (methods) for harnessing flow-induced electrostatic energy in an oil and/or gas well and using this energy to power electrical devices (e.g., flowmeters, electrically-actuated valves, etc.) downhole. The present invention is also directed to corresponding systems through which such methods are implemented.
