Attacking localized high amplitude noise in seismic data – A method for AVO compliant noise attenuation

Xinxiang Li and Rodney Couzens

…Summary The method of time-frequency adaptive noise suppression, or T-FANS, is designed to isolate and attenuate localized high-amplitude noise in seismic data. By “localized” we mean not only that the noise has a limited range in the space and time domain but also in the frequency domain. Strong ground roll…

Single Arrival Kirchhoff Prestack Depth Migration of complex faulted folds from the Zagros Mountains, Iran

Behzad Alaei and Jan Pajchel

…Abstract Migration is an important stage in seismic imaging that focuses the recorded seismic data and generates a true structural image of the subsurface. In complex fault and fold thrust belts with rough topography, migration is difficult owing to lateral velocity changes and also very steep dips. The geometry of…
