Regionalized data e.g. seismic data, spatial density index finding method for e.g. petrol reservoir characterization, involves providing ratio between combination of standard deviations of estimation errors and coherent components, as index

摘要

The method involves calculating standard deviations of estimation errors (2`, 5`) respectively associated to first order coherent components (2) and first order residues considered as second order coherent components (5). A ratio between all combination of the standard deviations and components provides a spatial density index (SDI). Anomalistic data is located with respect to their spatial samples from the SDI.
