Abstract
Method for efficient inversion of controlled-source electromagnetic survey data to obtain a resistivity model of the subsurface of the survey area. The method extracts the dimensions and location of sub-surface structures as they may be revealed by existing seismic or other available high resolution survey data from the subsurface area (). This structure geometry information is used to construct a discretization (grid, or mesh) for the inversion computation () that is different from the mesh used for the forward modeling calculations () in that (a) it has fewer and hence larger cells; and (b) the cells honor the assumed structural information. The inversion need only extract resistivity information (), the geometry of the resistive structures being specified by the inversion mesh.
