... The high productivity blended acquisition technique greatly improves the acquisition efficiency. However, this also introduces serious interference noise from adjacent sources. An deblending method based on sparse inversion is used to separate the effective major source signal from the massive...

... Conventional seismic data acquisition surveys usually require a firing time delay from each source to prevent energy overlaps between the numerous shot records. Recent advancements in continuous seismic recording systems and data separation workflows have enabled us to acquire seismic data from...

... We introduce a new filtering method for both detrending and local separation of potential field anomalies. The method is based on the modelling of a set of equivalent sources with the smallest possible volume, a sort of “atoms” selected among the many possible model that satisfy the potential...

... Ocean bottom node (OBN) seismic data processing commonly uses the combination of hydrophone (P) and vertical geophone (Z) components to separate upgoing and downgoing wavefields while attenuating ghosts and multiples. Because the vertical components are often contaminated by strong converted...

... Simultaneous source acquisition significantly reduces the acquisition time and cost in comparison with conventional single source acquisition. However, the blended data require deblending to separate them into that equivalent of the single source wavefield. In this work, we devise a denoising...
