1. A computer-implemented method comprising: obtaining a one-dimensional voxel vector for a voxel from multiple voxels associated with a formation of interest; obtaining spectral data generated from well-log data associated with an attribute of interest; coupling the spectral data with the one dimensional voxel vector to determine whether a resonance event occurs; when a resonance event occurs, producing an output indicating that the voxel has the attribute of interest; and when the resonance event does not occur, producing an output indicating that the voxel does not have the attribute of interest.
