Abstract
A monochromatic seismic source and seismic receivers are used to monitor the real-time dynamic behavior of a subsurface region. A seismic source is used to emit a monochromatic wave into the subsurface region and multiple seismic receivers are positioned within the subsurface region to receive the monochromatic wave. Phase variations in the monochromatic wave are measured using a phase-sensitive detection tool and the phase variations are used to determine changes in subsurface properties of the subsurface region.

A system for monitoring subsurface properties, the system comprising:
- a seismic source configured to emit a monochromatic wave into a subsurface region;
- seismic receivers configured to receive the monochromatic wave after the monochromatic wave has traveled through the subsurface region;
- and
- one or more physical processors configured by machine-readable instructions to:
- monitor phase variations in the monochromatic wave received by the seismic receivers using a phase-sensitive detection tool;
- and
- determine changes in one or more properties of the subsurface region based on the phase variations in the monochromatic wave received by the seismic receivers.
A method for monitoring subsurface properties, the method comprising:
- emitting, via a seismic source, a monochromatic wave into a subsurface region;
- receiving, via seismic receiver, the monochromatic wave after the monochromatic wave has traveled through the subsurface region;
- and
- monitoring, via one or more processors, phase variations in the monochromatic wave received by the seismic receivers using a phase-sensitive detection tool;
- and
- determining, via the one or more processors, changes in one or more properties of the subsurface region based on the phase variations in the monochromatic wave received by the seismic receivers.
