Device, medium and method for generating a multidimensional image of a subsurface of the earth. The method includes receiving (702) data related to the subsurface of the earth; generating (704) an ensemble of realizations associated with the subsurface based on the received data; applying (706) wavelet re- parametrization to spatial properties of the members of the ensemble to calculate a set of wavelet coefficients; reconstructing (708) the spatial properties of the ensemble based on a subset of the wavelet coefficients; applying (710) a forward simulator to the reconstructed spatial properties of the ensemble for estimating one or more physical parameters of the subsurface; applying (712) an ensemble-based optimization method to update the subset of the wavelet coefficients; and generating (712) multidimensional image of the subsurface based on the updated subset of the wavelet coefficients. |
