Abstract
A method of passive surveying comprises generating one or more detected signals by passively detecting a signal generated within a subsurface earth formation due to a seismoelectric response or an electroseismic response in at least one porous subsurface earth formation containing at least one fluid, and processing the one or more detected signals to determine at least one property of the subsurface earth formation.
Claims30
A system for surveying, comprising:
- an electromagnetic sensor configured to detect an electromagnetic signal generated by a subsurface earth formation in response to a passive-source electromagnetic signal, wherein the electromagnetic signal is generated by an electroseismic or seismoelectric conversion of the passive-source electromagnetic signal;
- a seismic sensor configured to detect a seismic signal generated by the subsurface earth formation in response to a passive-source electromagnetic signal, wherein the seismic signal is generated by an electroseismic or seismoelectric conversion of the passive-source electromagnetic signal;
- and
- a signal processor configured to:
- receive the electromagnetic signal from the electromagnetic sensor;
- receive the seismic signal from the seismic sensor;
- and
- process the electromagnetic signal and the seismic signal to determine at least one property associated with the subsurface earth formation.
