Slanted waves

 

In this final chapter of the book are gathered together imaging concepts that have been published, but have not yet come into routine industrial use. The first part of this chapter develops the mathematical concept of linear moveout and how it relates to velocity analysis. Data can be focused so that the interval velocity can be read directly. The latter part of the chapter is about multiple reflections. Here too linear moveout helps to define the problem. You will see basic mathematical tools that have the power to deal with multiple reflections and lateral velocity variations. This chapter has many data processing proposals. They are not descriptions of production processes!
