Abstract
An adjacent well telemetry system for changing the operational state of a downhole device and a method for use of the system is disclosed. The system comprises an electromagnetic transmitter disposed in a wellbore that transmits an command signal that is received by an electromagnetic receiver disposed in an adjacent wellbore. The electromagnetic receiver sends the command signal to an electronics package that generates a driver signal in response to the command signal that prompts the downhole device to change operational states.
