Abstract
A novel ocean bottom high-resolution magnetotellurics station is integrated with advanced nonlinear seismic tomography to build a high resolution, geologically accurate upper crust model characterized by a high level of spatial resolution. The integrated model provides the degree of accuracy needed by depth migration to properly image under highly variable covers and severe topography/bathymetry. The resolution of the final depth migration shows the potential of the proposed strategy to increase the value of seismic data and de-risk complex plays exploration programs. Technology has been successfully applied in Gulf of Mexico, North Sea Barents Sea and other oil and gas offshore provinces.
