Innovative Explorationsmethoden in der Gravimetrie und Reflexionsseismik

A survey on multiscale mollifier decorrelation of seismic data

“…The aforementioned wavelet construction is particularly powerful because of its "geophysical relevance", i.e., it forms a compromise reflecting the underlying physics (in accordance with the underlying differential equation) while still delivering an adequate multiscale decorrelation of geological signatures. Blick et al (2018b) strata can be detected, but of course not the specific geological formations themselves. Nevertheless, the structure of the geological configuration and even the faults become visible by mollifier decorrelation.…”

“…In the case of gravimetry, the mollifier method has been worked out and was realized by Freeden (2021), Freeden and Bauer (2020), Freeden and Nashed (2020), Freeden and Sansò (2020), Berg et al (2020), Blick et al (2018a), Freeden and Nashed (2018c), Freeden and Nashed (2018d), Blick et al (2017), Möhringer (2014), and Freeden and Gerhards (2013) (see also the references therein). A similar technique applied to migration results via the Helmholtz equation is discussed in Blick et al (2018b) and Augustin et al (2014). For a summary of both methods, the reader is referred to Freeden et al (2019), Freeden and Nutz (2015), and Freeden (2010).…”
