 | Zhdanov, Michael S. | Integral electric current method in 3-D electromagnetic modeling for large conductivity contrast | Abstract-We introduce a new approach to 3-D electromagnetic (EM) modeling for models with large conductivity contrast. It is based on the equations for integral current within the cells of the discretization grid, instead of the electric field or electric current themselves, which are used in the c... | Electromagnetic modeling; integral electric current method; 3-D modeling; high conductivity contrast; integral equations | 2007-05 |

 | Zhdanov, Michael S. | Novel approach to the model appraisal and resolution analysis of regularized geophysical inversion | The existing techniques for appraisal of geophysical inverse images are based on calculating the model resolution and the model covariance matrices. In some applications, however, it becomes desirable to evaluate the upper bounds of the variations in the solution of the inverse problem. It is possib... | Geophysical inversion; electromagnetic modeling; cauchy inequality; resolution analysis; lanczos decomposition method; SLDM; voisey's Bay; 3-D modeling | 2006 |

 | Zhdanov, Michael S. | Integral equation method for 3D modeling of electromagnetic fields in complex structures with inhomogeneous background conductivity | We present a new formulation of the integral equation (IE) method for three-dimensional (3D) electromagnetic (EM) modeling in complex structures with inhomogeneous background conductivity (IBC). This method overcomes the standard limitation of the conventional IE method related to the use of a horiz... | 3-D modeling; integral equation method; marine controlled-source electromagnetic data; MCSEM; gemini prospect; Gulf of Mexico | 2006 |

 | Zhdanov, Michael S. | Fast numerical modeling of multitransmitter electromagnetic data using multigrid quasi-linear approximation | Multitransmitter electromagnetic (EM) surveys are widely used in remote-sensing and geophysical exploration. The interpretation of the multitransmitter geophysical data requires numerous three-dimensional (3-D) modelings of the responses of the receivers for different geoelectrical models of comple... | multitransmitter electromagnetic data; numerical modeling; multigrid quasi-linear approximation; quasilinear approximation; geophysical exploration; 3-D modeling | 2006-06 |
