... we consider more automated handling of the acquisition footprint in FWI projects. We introduce a footprint removal method, that is computationally efficient and requires little or no parameterization. This means it can be deployed as part of an automated FWI workflow, requiring minimal user...

... to reconstruct the missing seismic records. Using linear-type (zigzag or sinusoidal) geometries can lead to fewer seismic cutlines compared to the conventional orthogonal surveys and hence can substantially reduce the environmental footprints of seismic surveys. However, it is important to increase the trace...

The results suggest that given...

... Ocean Bottom Node/Ocean Bottom Seismometer (OBN/OBS) data are currently sparse due to the acquisition costs in offshore oil-gas seismic exploration. Sparse spatially sampling of OBN/OBS highlights the problem of imaging acquisition footprints, poor phase continuity, and low signal-to-noise (S/N...

ABSTRACT This abstract present a local morphological component analysis (MCA) based acquisition footprint suppression method, which is based on adapted dictionary sparse representation of time slices. Firstly, the time slice of seismic data is divided into many patches, and all these patches...

... ABSTRACT When studying elastic wave anisotropy it is important to understand the relation between rock fabric (e.g. layering) and the elastic waves sensors in terms of their footprint and emitting wavelengths. We show that sensors with a small footprint (e.g. laser-ultrasonics) can probe...

... ABSTRACT Acquisition footprint often poses a major problem for 3D seismic data interpretation. Ideally, footprint from acquisition can be processed through more careful attention to trace balancing statics, noise reduction, and velocity analysis (Hill et al., 1999; Gülünay, 2000...

... ABSTRACT Acquisition footprint manifests itself on 3D seismic data as linear grid pattern of noise on time or horizon slices. Ideally, footprint suppression should be handled in the processing workshop. Unfortunately this is not an option for vintage poststack volumes where no pre-stack data...

We demonstrate that 5D interpolation/regularization for converted-waves, either in the sense of surface-consistent or ACP-consistent, is an important processing step in generating PS PSTM gathers in COV domain, resulting in reduced footprint and migration artifacts. The ACP-consistent...
