oa A Perspective on the Evolution of Processing Seismic Primaries and Multiples for a Complex Multidimensional Earth

Seismic reflection events are typically catalogued as primary or multiple depending on whether the arriving energy at<br>the receiver has in its history experienced one or more upward reflections, respectively. We can trace the evolution<br>of progress and effectiveness in seismic processing by following the physics used to describe what the wave<br>experiences between source and receiver. More realism and completeness in the physics, when applied<br>appropriately, has an associated improvement in prediction and reduction in risk. Hence, there is alignment between<br>providing step-change improvement in seismic effectiveness and a central need of the petroleum industry.
