Imaging with surface-related multiples to overcome large acquisition gaps
A Nath, DJ Verschuur - Journal of Geophysics and Engineering, 2020 - academic.oup.com
To get the best result for seismic imaging using primary reflections, data with densely-
spaced sources and receivers are ideally preferred. However, dense acquisition can …

On the role of multiples in Marchenko imaging
Marchenko imaging can produce seismic reflection images in which artifacts related to
multiples are suppressed. However, in state-of-the-art implementations, multiples do not …

Imaging strategies using surface-related multiples for incomplete seismic data
A Nath, D Verschuur - SEG Technical Program Expanded Abstracts …, 2016 - library.seg.org
Seismic surveys are often restricted due to finite number of receivers as well as missing near
and far offsets, thus affecting the illumination of subsurface. Surface-related multiples are …
