Modeling and sensitivity analysis of marine controlled-source electromagnetic fields in two-dimensional general anisotropic media

摘要：

　　In this paper, we implement the numerical simulations of marine controlled-source electromagnetic (CSEM) fields in the general case of anisotropy by using an adaptive finite element approach.The adaptive finite element method is employed to obtain numerical solutions on a sequence of refined unstructured triangular meshes, which allows for arbitrary model geometries including bathymetry and dipping layers.The sensitivity analyses show both the anisotropy strike and dipping angles have great influence on the marine CSEM responses.
