Abstract:
Three-axis velocity data, obtained along with pressure data in a marine seismic survey, are rotated to a ray direction. Plane wave decomposition is applied in the ray direction to the rotated velocity data. The pressure data and the velocity data are combined to generate at least one of up-going and down-going wave fields. The at least one of up-going and down-going wave fields are used in a time-space domain to image the earth's subsurface.
