Abstract: A method for using an offset vector tile gather to image a subsurface defines an offset vector tile gather by selecting a plurality of seismic traces from recorded seismic data. Each seismic trace in the offset vector tile includes reflections from subsurface reflectors and reflection points at depths below the surface of the subsurface. Each reflection point is in a given seismic trace, and each given seismic trace extends from a seismic source to a seismic receiver. The reflection points define an offset vector tile having a source line span and a receiver line span. The source line span is equal to or greater than a distance between adjacent seismic receiver lines, and the receiver line span is less than a distance between adjacent seismic source lines. The offset vector tile gather is used to produce a three dimensional image of the subsurface.

Abstract: Systems and methods for reducing survey time while enhancing acquired seismic data quality are provided. Data corresponding to plural source lines are acquired simultaneously, using sources at cross-line distance at least equal to their illumination width, with at least one source being towed above a streamer spread.
