Natural field electromagnetic acquired conventionally, at a number of sparsely spaced single sites, can suffer from spatial aliasing and significant distortive shallow effects which severely limit its geophysical applications. A new mode of data acquisition which measures the electric field continuously along a profile has been developed by F.X. Boxtick. These data can be processed to remove shallow effects while maintaining the deep penetration characteristics of the natural electromagnetic (EM) fields. Processing and modeling techniques for such data are discussed and demonstrated on both synthetic and field data. Very good agreement with actual borehole data is demonstrated.
