Abstract
Seismic simulation technology has been developed for many years. Recent trend that targets of exploration have become deeper and more complicated recalls demand of the seismic simulation technology. However, it has been only used for limited study due to various technical reasons. In recent years, the seismic simulation technology is rapidly advanced with new simulation methods and parallel computers. We have developed the wave propagation methods and applied to various exploration problems. We will show some results of seismic simulation in this paper.The first example is related to the Marmousi model. This simulation result shows that the wave propagation is very complicated and is beyond our image. The second example is a virtual seismic survey related to the sub-salt play. The virtual exploration shows the problems and solutions for sub-salt seismic imaging. The third example is the difference between acoustic and elastic modeling. This result shows the problem in onshore seismic data and the future direction.Using a seismic simulation, we can recognize various pitfalls and limitation in seismic processing and seismic interpretation. Seismic simulation can be used as potential tools for virtual explorations. We can gain the knowledge and the virtual experience through the virtual explorations.
