Abstract

A seismic acquisition survey should be designed in a way<br>that fulfils the imaging requirements while satisfying the<br>economical constraints. Common Reflection (CRP) stack<br>on the surface is able to describe the true amplitude on the<br>subsurface. The computed forward modeling based on CRP<br>can be done efficiently by using wavefront construction<br>with two-point raytracing(Chang, Downie, 1995, 1996;<br>Chang, et al., 1997, 1998). The synthetic amplitude<br>information in the subsurface can also be put on the surface<br>based on the raypath information in the presence of<br>complex subsurface. The main contribution of this work is<br>to provide theoretical amplitude attributes based on CRP<br>stack on both the surface and target horizon for complex<br>models. These attributes can provide the valuable<br>information for an acquisition layout and an appropriate<br>depth imaging sequence. Ideally, the receivers should be<br>placed on the area with maximum energy return as shown<br>in Figure 1.
