Patent ID: 6894949

Claim:
A method of determining a parameter of interest of a portion of a reservoir in earth formations comprising: (a) deploying a first plurality of seismic receivers in a first well and a second plurality of receivers in a second well, said first well and said second well disposed on opposite sides of said portion of the reservoir; (b) generating seismic waves at a plurality of locations at or near the surface and propagating said seismic waves in said earth formations at at least one epoch; (c) receiving first signals indicative of said propagating seismic waves at said first and second plurality of seismic receivers at said at least one epoch; (d) receiving second signals indicative of seismic waves reflected from a boundary below said portion of the reservoir at a third plurality of receivers at or near said surface; and (e) performing a tomographic analysis of said first and second signals for obtaining said parameter of interest at said at least one epoch.
