In traditional seismic surveys the firing time between shots is such that the shot records do
not interfere in time. In the concept of blended acquisition, however, shot records do overlap …

Blended source arrays are historically configured with equal source units, such as
broadband vibrators (land) and broadband air-gun arrays (marine). I refer to this concept as …

Dense, wide‐aperture and broad frequency band acquisition improves seismic imaging and
potentially allows the use of full waveform inversion for velocity model building. The cost of …

Recently much attention has been given to the possibility of shooting in an overlapping
fashion, the so‐called blended or simultaneous acquisition. In conventional acquisition the …

Blended or simultaneous sources have been the focus of a good deal of interest recently. In
conventional acquisition the time intervals between successive sources are large enough to …

When in the fall of 2008 I was chosen as the 2011 Distinguished Instructor Short Course
lecturer on seismic acquisition, I felt honored, puzzled, and worried. Of course I felt honored …

Pseudorandom vibroseis sweeps have long been suggested as an alternative to standard
linear sweeps due to their potential for having superior orthogonality, a lower likelihood for …

If simultaneous shooting is carried out by incoherent source arrays, being the condition of
blended acquisition, the deblending process generates shot records with a very low residual …

We introduce the distance‐separated dithered slip‐sweep vibroseis acquisition technique
with the objective of maximizing acquisition productivity for land data whilst maintaining the …

Conventional multichannel surveys provide good images in 2D and 3D of the Earth in depth,
which are successfully used for the oil and gas industries. However, their cost and …
