METHOD FOR OBTAINING AN OPTIMAL MODEL OF A PHYSICAL CHARACTERISTIC LOAD IN A HETEROGENEOUS MEDIUM, SUCH AS SUBSURFACE SOIL

摘要

a method for the inversion process.an optimum model of a physical characteristic in a heterogeneous medium, the impedance of an underground zone relativu00e9ment in transmitted wave in the soil, for example).based on a priori model of the magnitude that are optimized by minimizing a cost function depending on the differences between the desired and known data.in view of the a priori model.the construction of the a priori model includes a correlation between the values of the aim of physical quantity in different points of the middle of discontinuities (directions of scapacity).the uncertainties in the values of the physical quantity in the a priori model compared to the corresponding values in the community are a model of covariance control, morequantitative parameters of inversion, the characteristics of the model are defined in conjunction with the covariance structure of the measured or observed data in the field.the guiding shells is better in the selection of inversion parameter. applications for the location of hydrocarbon reservoirs for example.
