SYSTEM AND METHOD FOR TIME-DISTANCE CHARACTERISTICS IN ACQUISITION, PROCESSING AND IMAGING OF T-CSEM DATA EXPLOITING CONTROLLED SOURCES IN TIME DOMAIN

摘要

There is provided herein a system and method of acquiring, processing, and imaging transient Controlled Source ElectroMagnetic (t-CSEM) data in ways that are similar to those used for seismic data. In particular, the instant invention exploits the time- distance characteristics of t-CSEM data to permit the design and execution of t-CSEM surveys for optimal subsequent processing and imaging. The instant invention illustrates how to correct t-CSEM data traces for attenuation and dispersion, so that their characteristics are more like those of seismic data and can be processed using algorithms familiar to the seismic processor. The resulting t-CSEM images, particularly if combined with corresponding seismic images, may be used to infer the location of hydrocarbon reservoirs.
