Abstract

Summary

Passive seismic interferometry is a relatively new image method and has been applied for many engineering and exploration geophysical investigations. It includes two major methods which are cross-correlation and autocorrelation. The cross-correlation of ambient noise record between two receivers will generate a virtual shot at one receiver location. Autocorrelation of a passive seismic data trace can be considered to yield a conventional zero-offset trace. The autocorrelation of all traces in the passive seismic gather can be considered as a zero-offset section. Both methods could be used in the passive seismic data imaging. In this study, we apply both methods to a passive data set acquired at a well-known geological storage site, Ketzin. We processed the passive data sets by autocorrelation and cross-correlation. We compared the stack sections obtain by autocorrelation, processing of shot gathers got by cross-correlation and active survey. The autocorrelation sections surprisingly have a very good agreement with the active stacked section. The stack sections obtain by processing virtual shot gathers obtained by cross-correlation show some similar features compared with the active stacked section but much worse than the autocorrelation section.
