In this abstract some examples will illustrate the importance of analyzing illuminating beams for accurate imaging and locating important target zones in the subsurface. The analysis of illuminating beams through subsurface models provides insight to optimally acquire all necessary seismic data with the objective to image more accurately the subsur...

... the situation that the subsurface model is more complex e.g. the SEG/EAGE salt model ( Aminzadeh et al., 1995Aminzadeh et al., , 1996, the following illustration will show the effect of the salt body to the illuminating beam and its appearance and complexity. Figure 2 shows an illuminating beam from a point source in depth (see arrow for location of the point source). ...
Context 2
... this example, a point source was chosen in the subsurface and the illuminating beam was calculated for the waves propagating from the depth to the surface. This example was chosen to provide insight to the importance of a b data acquisition for subsalt imaging : e.g. if point sources would have been selected at the surface (including the two specific locations at the surface of Figure 2), then those point sources would optimally contribute to the imaging of the subsurface point (shown by arrow in Figure 2); this is the reciprocal situation of exchanging sources and receivers. ...

In this paper a strategy is outlined to analyze illuminating beams for optimally locating target zones, and optimally acquiring all necessary seismic data. Illumination analysis of wave propagation through the earth s subsurface plays a very important role, in locating shadow zones and target prospects, to optimize the success of exploration wells....
