Abstract: Systems and methods of performing a seismic survey are described. The system can receive seismic data. The system receives seismic data from one or more seismic data sources. The system propagates the seismic data forward in time through a subsurface model to generate a first wavefield. The system propagates the seismic data backward in time through the subsurface model to generate a second wavefield. The system combines the first wavefield with the second wavefield using a time gate imaging condition to produce subsurface images and image gathers.

Abstract: The present disclosure is directed to detecting subsurface features via a seismic survey. A system can obtain seismic data from nodes separated from each other by at least a threshold distance on a ground surface. The seismic data can include image trace data based on field trace data detected from each of the plurality of seismic data acquisition units. The system retrieves a sample interval and a parameter. The system configures a bandlimited binning function with the sampling interval and the predetermined parameter. The system applies the bandlimited binning function to a plurality of image traces of the image trace data to generate a bandlimited angle gather value for a bin in an angle gathers grid. The system generates an image based on the angle gathers grid and provides the image for display.
