A method and device for processing a seismic survey data set including: an actual source location, an actual receiver location, and an actual reflection event location is provided. The actual source location and actual receiver location are over a first layer having a first layer velocity and a first layer ray parameter, and over a second layer having a second layer velocity different from the first layer velocity and a second layer ray parameter different from the first layer ray parameter. The actual reflection event location is located below the first layer. The method comprises: providing the first layer velocity; providing the second layer velocity; providing the first layer ray parameter; providing the second layer ray parameter; determining a correction factor for the position of a ray path end dependant upon the first and second layer velocities and the first and second layer ray parameters; and applying the correction factor to the ray path end, wherein a ray path-corrected ray path end is provided. The ray path end comprises a member of the group consisting of: the actual source location, the actual receiver location, and the actual reflection event location. The ray path corrected ray path end comprises a member of the group consisting of: the ray path corrected source location, the ray path corrected receiver location, and the ray path corrected reflection event location. |
