Claim One:
1. A method for determining a value of a designated rock or fluid property in a subterranean geologic volume, the method comprising: assigning a first predicted value of a rock or fluid property to a cell within a multi-dimensional layered model that is correlated to a subterranean geologic volume; calculating a first predicted value of a seismic response for said cell from a response model using said first predicted value of said rock or fluid property, wherein said response model is responsive to changes in predicted values of said rock or fluid property; comparing at least one synthetic trace that is generated from said first predicted value of seismic response to the corresponding trace obtained from one or more sets of actual seismic data corresponding to the subterranean geologic volume to ascertain a difference between said synthetic trace and said corresponding trace, said step of comparing involving maintaining consistency between the types, scales and dimensions of said first predicted value of a designated rock or fluid property and said actual seismic data; adjusting said first predicted value of said designated rock or fluid property in response to said difference to create a second predicted value of said designated rock or fluid property, wherein said second predicted value generally reduces said difference.
