Abstract
Predicting elastic parameters of a subsurface includes modelling changes in the shear modulus and changes in the bulk modulus of the subsurface as a combination of a host medium shear modulus and host medium bulk modulus and a plurality of inclusion shear moduli and inclusion bulk moduli. Each inclusion shear modulus and inclusion bulk modulus associated with a unique inclusion geometry. An inclusion-based rock physical model is used to solve the models for changes in shear modulus and changes in bulk modulus to predict an effective shear modulus of the subsurface and an effective bulk modulus of the subsurface.
