摘要： A method and system for forming a seismic image of a subterranean region are disclosed. The method includes determining an initial plan for a seismic survey with a value for each member of a set of acquisition parameters and acquiring a first seismic dataset from a first portion of the seismic survey based on the initial plan. The method further includes transmitting the first seismic dataset to a seismic processor, determining a first seismic image from the first seismic dataset by performing expedited seismic processing and determining a first updated plan for the seismic survey based on the first seismic image and acquiring a second seismic dataset from a second portion of the seismic survey based on the first updated plan. The method still further includes transmitting the second seismic dataset to the seismic processor and determining the seismic based on the first seismic dataset and the second seismic dataset.

摘要： A method may include determining various migrated azimuthal dip-angle gathers based on a migration function and seismic data from a seismic survey regarding a geological region of interest. The method may further include determining various partial dip-angle images using the migrated azimuthal dip-angle gathers. The method may further include determining various azimuthal bins that include the partial dip-angle images. The method may further include determining various wavefield components using an independent component analysis (ICA) function and the partial dip-angle images among the azimuthal bins. The method may further include determining a geological feature within the geological region of interest using the wavefield components.
