Three-Dimensional Anisotropic Inversion for Direct Current Resistivity Method Using Unstructured Tetrahedral Discretization

Many rocks exhibit electrical anisotropic characteristics, leading to artifacts in isotropic inversion of dc resistivity data. To mitigate this issue, we employ the flexible unstructured finite element (FE) method for 3-D anisotropic forward modeling and anisotropic inversion for dc resistivity data...
