Abstract

We present a novel approach for integrating electrical conductivity in 3D seismic inversion based on Gramian constraints. In the framework of this approach, the P-wave velocity inversion is guided by an electrical conductivity model. In order to introduce a structural coupling between the two models, we minimize the corresponding Gramian functional, which is included in the Tikhonov parametric functional. We also demonstrate how this method can be incorporated in a standard minimization scheme. The method of integral equations was exploited as the forward modeling operator. The developed new approach of electrically guided inversion of seismic data was validated by inverting synthetic pressure response for a number of models.
