Adequate velocity model as a basis for effective seismic imaging when mapping hydrocarbon traps associated with salt domes

This paper is the second one in a series of tutorials on the usage of modern migration methods for seismic imaging in areas of intense salt tectonics. In the paper, it is shown the importance of building an adequate velocity model for effective seismic imaging and subsequent mapping of hydrocarbon t...
