And you drill through hard rock to get to the hydrocarbons. But Stu is right – it’s one of the more interesting massively parallel (but not necessarily embarrassingly) problems, because the propagation medium is anisotropic. By comparison SAR (Synthetic Aperture Radar), tomography,and finite element electromagnetics processing are a doddle. Some mechanical FEM codes are tricky, and non-linear flow (shock waves, etc.) are complex.
Everyone who deals with these sorts of problems is all about efficiency and “good approximations” – you typically start with a linearized approximation, and then iterate with something to get the nonlinear solution – all of this takes lots o’ cycles.
