Problem 1, back scattered energy, causes much noise in the data. This is especially a problem because 80–90% of the energy of a surface source can end up in the near surface waveguide rather than imaging reflections. Problem 2, complex structure below the surface, distorts the down going wavefield and makes stacking and imaging challenging. These velocity variations are often too deep for refraction statics methods or do not adhere to the statics model. These shallow velocity variations are often very strong and small scale so they are difficult to resolve with refraction or reflection tomography methods. The combination of these two problems, much noise and complex structure, can make improving on a basic image very challenging. Passive seismic interferometry can address these two basic problems with the following: 1) The ability to record the very low frequencies (< 3Hz) that are necessary to resolve the strong, small scale velocity variations in the shallow part of the section, and 2) Cost effective use of 2D areal arrays to filter out back‐scattered energy at the source and receiver. The most direct way of using the very low frequencies to resolve shallow part of the section is with full waveform inversion, which has been shown to be robust with these low frequencies. It is often challenging to acquire these very low frequencies with land data in high quality with conventional sources. Although receiver technology has improved dramatically in recent years and can record very low frequencies, sources have difficulty putting significant energy in the ground at these low frequencies. Passive seismic interferometry avoids this low frequency source problem by using the existing passive energy already in the earth. Studies of the passive energy in the earth show that it is very energetic in this low frequency band. The technique for using the passive energy in the earth to generate conventional seismic reflection data is seismic interferometry. Acquiring the very low frequencies with seismic interferometry can be a significant complement to conventional seismic reflection data and can aid several imaging shortfalls with the existing frequency content of conventional data.Permalink: https://doi.org/10.1190/1.3255531FiguresReferencesRelatedDetails SEG Technical Program Expanded Abstracts 2009ISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2009 Pages: 4338 publication data© 2009 Copyright © 2009 Society of Exploration GeophysicistsPublisher:Society of Exploration Geophysicists HistoryPublished: 14 Oct 2009 CITATION INFORMATION Christof Stork, (2009), Addressing key land data quality challenges with passive seismic interferometry, SEG Technical Program Expanded Abstracts : 3238-3243. https://doi.org/10.1190/1.3255531 Plain-Language Summary PDF DownloadLoading ..." @default.
