AbstractAbout the AuthorReferences
The article discusses the method of extended correlation for vibroseis data, which enhances the depth of investigation without the need for additional field surveys. Two main modifications of the method are described: fixed-bandwidth and self-truncating extended correlation. Examples of successful international applications are provided, along with the results of its testing on the Yuryuzano-Sylvensky area using vibroseis profiling data. The study demonstrates that the method increases the correlogram duration up to 22 seconds, enabling the acquisition of new information about the deep structure of the Earth’s crust.
