Abstract: A method and system includes acquiring a seismic dataset while fluids are injected into the subsurface with seismic data recorded at multiple sensor locations. Seismic travel times are computed between sensors and subsurface locations using a velocity model. Travel times and travel time delays between pairs of sensors may be used as input to determine a similarity coefficient associated with subsurface positions. The similarity coefficients are determined using cross correlation, semblance calculations or eigenstructure decomposition. The coefficient values are related to the acoustic response at each subsurface position and may be summed together for each position for comparison with other subsurface positions to determine the position of a fluid front moving through the subsurface. The values may be displayed to illustrate the position of fluids in the subsurface and displayed to show the time variance of the fluid position.

Abstract: The disclosure teaches an interactive 3 dimensional microseismic event color visual display method comprising the steps of displaying an interactive 3D visual image of 3 dimensional data of microseismic event data occurring from geologic stimulation and manipulating the visual display by changing a blend mode of microseismic event data among alpha blending, additive blending, and opacity by factors comprising color, size, event location, and translucency wherein such factors correlate to amplitude, location, depth, probability, direction, time, distance from wellbore and combinations thereof.
