METHOD TO DISTORT GRADUALLY A STOCHASTIC MODEL OF A HETEROGENEOUS ENVIRONMENT SUCH AS A SUBSURFACE ZONE

摘要

method for deforming a gradual, or a local gaussian stochastic model of a heterogeneous medium or similar, such as an underground area.constrained by a set of parameters related to the structure of the environment.the method includes drawing a number p of at least two independent outputs of at least a part of the model of the environment,among all the possible outcomes, and a linear combination of these coefficients with p p outputs, such as the sum of the squares is equal to 1.this linear combination is a new realization of the stochastic model, and it is gradually when changing p coefficients.the method may include, more generally, several iterative steps of progressive deformation.with combination at each stage of a composite obtained in the previous stage, achieve new record with q independent from the overall performance.the method provides the possibility to deform gradually the achievements of a representative model of the environment by modifying the statistical parameters related to the structure of the environment.the method also allows incremental deformation of individual sections of the model while preserving the continuity between them.application to the construction of stochastic models of aircraft nonlinear data storage, data related to the flow of fluids.
