- W1968046459 abstract "Migration—the correction positioning of reflector elements—is as old as reflection seismics itself; Karcher’s observation of the Viola limestone was correctly migrated in x and z. Today, perhaps, we would call this process “post‐picking event migration.” First, reflections (i.e., segments of reflection hyperbolae) were identified (“picked”) on the raw paper record. Next, the position of the corresponding reflector element was determined from the geometry of shot and receivers, from the arrival times of the reflections, and from velocity information. Finally, the reflector elements were posted on the section and connected to the reflector." @default.
