Abstract:
1. A system configured to sense a pressure in a subterranean environment, the system comprising: a signal generator configured to generate an electromagnetic signal; a sensor probe configured to be located within a region of the subterranean environment, the sensor probe including a resonant circuit portion that includes a capacitive element, the resonant circuit portion being further configured to receive energy from the electromagnetic signal and to generate a resonant signal in response to the electromagnetic signal, wherein the capacitive element of the sensor probe is responsive to a pressure condition in the region of the subterranean environment to modulate the resonant signal in accordance therewith; the capacitive element comprising: a receiver configured to receive the modulated resonant signal; and one or more processors configured to process the modulated resonant signal to obtain a measurement of the pressure condition.
