Abstract

Because no exact method exists for multiparameter, multidimensional seismic inversion, approximate methods based on variations of the Born approximation are significant. Artifacts which result from its linear nature limit the usefulness of multiparameter Born inversion. These artifacts can be identified by inferring from the differential equation that portion of the Fourier transformed data that is most consistent with the approximate linear Born relationship. When this portion of the data is inverted, the true parameter changes may be distinguished from linear artifacts.
