Method of subsurface imaging using superposition of sensor sensitivities from geophysical data acquisition systems

摘要

Volume imaging of geological structures and/or man-made objects having physical property using geophysical field sources and/or sensors mounted from at least one data acquisition system. The sources may include natural field sources and/or man-made sources. The sensors may measure at least one component of the geophysical field. The subsets of the geophysical survey formed by the at least one source of geophysical data are selected, and the integrated sensitivity subdomains for selected subsets of the survey are determined by determining the volumes where the integrated sensitivity of the subset is greater than a predetermined threshold. The total sensitivity is determined as the superposition of the sensitivities from all of the integrated sensitivity subdomains. The fields measured for each combination of source and/or sensors may be volume imaged where 3D inversion/imaging is based on the total sensitivity calculated as the superposition of the sensitivities from all of the integrated sensitivity subdomains.
