SYSTEM AND METHOD FOR APPLICATION OF ELASTIC PROPERTY CONSTRAINTS TO PETRO-ELASTIC SUBSURFACE RESERVOIR MODELING

摘要

An information processing system having a processor and a memory device coupled to the processor, wherein the memory device includes a set of instruction that, when executed by the processor, cause the processor to receive a multi-dimensional grid of acoustic or elastic impedances determined from seismic survey data associated with a subterranean formation, receive elastic property data that describes elastic property characteristics used to sort pseudo-components, and wherein the respective pseudo-components are formed of a combination of two or more lithologies. The instructions, when executed by the processor, further cause the processor to define select design variables using the impedance arrays, perform optimization operations for optimizing select design variables by applying the elastic property data as a part of a constitutive relation, and output a distribution of the pseudo- components to characterize volumetric concentrations of spatially grouped lithologies in a control volume of the subterranean formation.
