摘要
Systems and methods for acquiring and processing electromagnetic data in subsurface formations. In one example, a system includes an electromagnetic source, a plurality of electromagnetic receivers, and an electromagnetic data processor. The electromagnetic source is configured to generate an electromagnetic pulse that induces electromagnetic energy in subsurface formations. The electromagnetic receivers are configured to detect the electromagnetic energy reflected by the subsurface formations, and to output signals corresponding to detected electromagnetic energy reflected by the subsurface formations. The electromagnetic data processor configured to process, based on differences in travel times of the electromagnetic energy between the subsurface formations and the electromagnetic receivers, the signals output by the electromagnetic receivers. The electromagnetic data processor is further configured to produce a representation of the subsurface formations based on processed signals output by the electromagnetic receivers.
