3-D Structurally Constrained Inversion of the Controlled-Source Electromagnetic Data Using Octree Meshes

In this article, we propose a structural constraint method to improve the resolution of 3-D frequency-domain controlled-source electromagnetic (CSEM) data imaging. The subsurface interfaces can be obtained from high-resolution seismic imaging data or reliable geological information. First, we assume...
