Method for determining specular information after seismic imagery prior to summation

Abstract From the Canadian patent

Method for determining the specular source/receptor pairs associated to seismic images produced based on a transformation of multi-offset recordings of seismic waves relative to time in the field of depth. When the depth migration algorithm is implemented before Kirchhoff summation the trajectory times required for the radii to get from the sources and the receptors of the acquisition device to the image points of the image to migrate are calculated and retained the parameters of the spokes of these radii are also calculated and retained as well as the quantities to which access is ultimately desired. Then once the migrated volume before summation is produced the slopes of local seismic …
