Abstract
Marine seismic data are acquired, using a seismic vessel. The acquired marine seismic data are transferred in near-real time to a programmable computer. The programmable computer is used to perform the following. An acoustic 3-D full-waveform inversion is applied to the transferred marine seismic data, generating a high-resolution 3-D velocity field in near-real time. The velocity field is used to apply migration to the transferred marine seismic data, generating an image of the earth's subsurface in near-real time.
