Abstract

Summary

As the effect of acquisition geometry can be evaluated by calculating illuminations of different shooting patterns, it is an important methodology to analyze imaging shadow and acquisition footprint, and optimize acquisition geometry design to improve the imaging quality of prestack depth migration. However, the illumination analysis based on wave equation is time-consuming. So the methodology is not widely used in practical survey design. In this paper, we present a new illumination methodology which combines sources to improve the computational efficiency of seismic illumination without losing wave field characteristics, a real seismic data from the survey which was optimized by the methodology indicate that the phase wave-sources-based seismic illumination analysis is a highly efficient tool to evaluate the effects of the designed seismic geometry.
