Claim 15:
16. A method for determining a permeability field architecture of at least a portion of a fluid reservoir, the method comprising the steps of:
establishing a seismic array in the vicinity of a wellbore in fluid communication with said fluid reservoir; wherein said seismic array is operable to acquire seismic energy emission data and said seismic array comprises a plurality of seismic energy sensors;
generating a change in fluid pressure in said fluid reservoir;
continuously acquiring seismic energy emission data from said seismic array during said change in fluid pressure;
processing a selected portion of said seismic energy emission data to generate a plurality of voxels corresponding to three dimensional spatial representations of fluid flow through said portion of said fluid reservoir, wherein said processing step includes identifying a semblance band for said data utilizing semblance filtering techniques;
generating a value of the permeability scalar K from a velocity of a fluid pressure wave through said portion of said fluid reservoir;
determining a permeability field architecture of said portion of said fluid reservoir based on said fluid flow; and
identifying at least one high permeability pathway in said fluid reservoir, wherein said high permeability pathway corresponds to a medial surface of said fluid reservoir.
