MultiFocusing 3D Diffraction Imaging
Berkovitch Alex, Deev Konstantin, Pelman Danil, Rauch - Davies Marianne
The new algorithm of 3D diffraction imaging is based on a MultiFocusing methodology and consists of optimal summation of seismic data in accordance with a diffraction-moveout formula. The diffraction-oriented stacked sections can be used for reliable interpretation of non-smoothed geological interfaces and for identification of local heterogeneities such as faults, karsts, fractures etc.
MultiFocusing based multiple attenuation
Berkovitch Alex, Landa Evgeny
The proposed MultiFocusing based multiple attenuation procedure is valid for surface-related as well as for interbed types of multiples. It is robust and simple. It is easy to implement and it can predict all kinds of multiples defined by the picked corridors in the MF domain. The multiple suppression approach with MF attributes is not dependent on the regularity of the data.
