oa Salt Around the World - Similarities and Differences

Subsalt imaging is seen as one of the most difficult imaging challenges in seismic processing. Although that is a discussion in itself, no one will question the fact that processing seismic for subsalt exploration is very complicated due to the structural complexities associated with salt, the complex multiples, as well as the associated velocity contrasts. When people discuss subsalt imaging challenges, they almost immediately associated these with the deepwater Gulf of Mexico issues. However, each salt basin has its own characteristic set of problems. In this paper we will discuss and illustrate different salt ‘types’ in different parts of the world, each of which has a specific set of issues and potential seismic solutions. We will discuss differences and simularities.
