Claim Text:
1. A method, comprising: drilling a well into a subterranean reservoir; estimating an initial structure of the reservoir layers and a spatial distribution of resistivity parallel to a bedding and perpendicular to the bedding along a trajectory of the well; conducting a surface electromagnetic survey; causing a processor to run an inversion of the surface electromagnetic survey using the estimated structure of the reservoir layers and the estimated spatial distribution of the resistivity; causing a logging while drilling tool to make logging while drilling measurements while drilling the well into the subterranean reservoir; generating a calibrated structure and/or a spatial distribution of resistivity parallel to the bedding and perpendicular to the bedding along the trajectory of the well being drilled based upon the logging while drilling measurements made while drilling the well; and causing the processor to run a subsequent inversion of the surface electromagnetic survey using said calibrated structure and/or spatial distribution of resistivity to obtain an improved inversion.
