.... Based on this study, we suggest that land acquisition geometry can also be designed as one-sided, rather than split-spread, to get maximum offsets. Utilizing reciprocity principle, the number of DPW components needed for DPW migration can be reduced by half, which increases the migration efficiency. DPW...

... dimension in 3-D land data creates a unique problem when statics corrections are to be estimated. Typical 2-D surveys normally provide sufficent fold so that an effective statics estimation can easily be made. However, in the case of 3-D data, details of the acquisition geometry become of crucial importance...

... on the spread. Modern wide-azimuth land acquisition geometries typically involve acquiring source points in small salvos of between 8 and 16 vibrator points (VPs). After completing a salvo the fleet moves to the next salvo; this results in a large number of crossline move-ups. To ensure maximum efficiency we...
