Large-Scale Seismic Modeling

This session addresses large-scale seismic modeling, the algorithms, the computational resources, the model parameters, and current issues. Seismic model studies are used extensively to validate geological concepts and test seismic inverse algorithms. Realistic two and three dimensional synthetic seismic models are both expensive to compute and time consuming. The speakers will address the relevant issues of algorithms, wave equations, numerical approximations, and computational science. Industrial examples will be discussed.
