Abstract
Disclosed is a method for characterizing the evolution of a subsurface volume over time. The method comprises providing a first and second surveys of the reservoir with a first and second sets of seismic traces, performing an inversion to obtain estimates of changes having occurred between said first time and said second time in terms of at least one model parameter; wherein the subsurface volume is divided into regions according to a high order discrete classification attributed in accordance with the region's geologic characteristics, and said inversion is constrained per region of subsurface volume. The regions of subsurface volume may be geological layers.
