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.
Claims23
A system for subsurface surveying comprising:
- one or more of an electromagnetic sensor and a seismic sensor located near or above the surface of the earth, wherein the electromagnetic sensor is 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 and wherein the seismic sensor is 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;
- a processor;
- and
- a memory, wherein the memory includes executable instructions that, when executed, cause the processor to:
- receive data corresponding to one or more of the electromagnetic signal generated by the subsurface earth formation in response to the passive-source electromagnetic signal and the seismic signal generated by the subsurface earth formation in response to the passive-source electromagnetic signal;
- and
- determine at least one property of the subsurface earth formation, based, at least in part, on one or more of the detected electromagnetic signal generated by a subsurface earth formation and the detected seismic signal generated by a subsurface earth formation.
