Abstract:
A method for forming a representation generated by sequential simulation, of a stochastic model, which is not limited to a Gaussian stochastic model, of a physical quantity z in a heterogeneous medium, in order to constrain the stochastic model to data collected in the heterogeneous medium by means of previous measurements and observations, relative to a state or the structure of the heterogeneous medium, comprising applying a stochastic model gradual deformation algorithm to a Gaussian vector (Y) with N mutually independent variables that is connected to a uniform vector U with N mutually independent uniform variables by a Gaussian distribution function (G), so as to form a chain of realizations u(t) of vector U, and using the chain of realizations u(t) to generate realizations z(t) of the physical quantity that are adjusted to the data with.
