Abstract
This disclosure presents computational systems and methods for obtaining high-resolution, three-dimensional seismic images of a region of a subterranean formation using separated up-going and down-going wavefields that include primary and multiple reflections obtained by processing dual-sensor towed streamer seismic data. The inclusion of multiple reflections reduces acquisition footprints in migration of the seismic data. The computational systems and methods produce high-resolution images in a region of a subterranean formation that lies below a body of water. The methods and systems employ a digitally encoded wavefields constructed from a discrete sampling of a two-dimensional slice of a three-dimensional wavefield and stored in one or more tangible, physical data-storage devices.
