Seismic exploration using non-impulsive vibratory sources activated by stationary, Gaussian codes, and processing that results in distortion- free final records particularly useful in stratigraphic trap determination

摘要

The disclosed invention is a method of seismic exploration using non- impulsive vibratory sources activated by stationary, Gaussian codes. The method has the channel-capacity economy of sign-bit recording and the distortion-free quality of full-waveform seismic records, even through zero memory, non-linear representations ("ZNL's") are employed either during the collection or the processing steps that produce such final records. As a result, stratigraphic facies can be both economically and surprisingly indicated.
