Abstract
Method for estimating fluid heterogeneity in a subsurface region from seismic wave attenuation or velocity dispersion that is either measured or extracted from geophysical data (). A rock physics model in the form of a mathematical relationship is selected that relates attenuation or velocity to frequency and to physical properties that are related to fluid heterogeneity (). The model, or asymptotes () representing the model's behavior at frequency extremes, is inverted () and that relationship is used to obtain () one or more of the physical properties related to fluid heterogeneity, such as characteristic length scale for fluid saturation heterogeneities () and relative volume fractions of the fluids saturating the pore space ().
