TEMPORAL ANALYSIS SYSTEM FOR THE SPECTRAL ENERGY OF SEISMIC WAVES INTENDED FOR THE DETECTION AND VISUALIZATION OF ZONES OF FLUID MOVEMENT AND ALTERATION IN A GEOLOGICAL SUBSURFACE

Abstract

The invention relates to a time-domain analysis system for the spectral energy of seismic waves, intended for the detection and visualization of areas of fluid movement and weathering in a geological subsurface. Spectral energy is the distribution of the energy of a wave as a function of a plurality of frequencies. The system is characterized in that it comprises an integer number M of sensors greater than or equal to 3. These sensors are configured to measure at least one wave propagating in the geological subsurface during an observation period to obtain at least one measurement signal. The sensors form sensor pairs, with a first sensor and a second sensor forming a sensor pair. The system also includes a controller for implementing a time-domain analysis method for the spectral energy of seismic waves, intended for the detection and visualization of areas of fluid movement and weathering in a geological subsurface.
