Title
(EN) Harvesting vibration for downhole power generation
Abstract
(EN)
A method usable with a well comprises deploying wireless tags 220 in the well to measure properties of the well as the tags flow through the well, and using vibrational energy transferred to the tags 220 during the flowing through the well to activate and power the tags 220. The tags 220 can be used to monitor various downhole conditions. The tags 220 can include a processor and the information gained by the tags 220 can be transmitted to an external reader.
