The reflected seismic wave 24 propagates upward until it is detected by receiver 11 on streamer 12. The seismic wave 18 propagates downward, toward the seafloor 20, and penetrates the seafloor until, eventually, a reflecting structure 22 (reflector) reflects the seismic wave. The vessel 10 also tows a seismic source array 16 configured to generate a seismic wave 18. The streamers may be disposed horizontally, i.e., lying at a constant depth relative to the ocean surface 14, or may have spatial arrangements other than horizontal, e.g., variable-depth arrangement. 1, a vessel 10 tows an array of seismic receivers 11 located on streamers 12. Thus, providing a high-resolution image of the subsurface is an ongoing process for the exploration of natural resources, including, among others, oil and/or gas.ĭuring a seismic gathering process, as shown in FIG. While this image/profile does not provide a precise location for oil and gas reservoirs, it suggests, to those trained in the field, the presence or absence of oil and/or gas reservoirs. Marine seismic data acquisition and processing generate an image of a geophysical structure (subsurface) under the seafloor. Embodiments of the subject matter disclosed herein generally relate to methods and systems and, more particularly, to mechanisms and techniques for redatuming and binning seismic data collected with different datums for improving a final image of a surveyed subsurface in a time-lapse or 4D project.
