Unfortunately, this approach still lacks the possibility of modeling, which is not possible straightforward with the demigration process. In this book, a new modeling technique is presented using demigration. Thus for the first time, a link is established between Kirchhoff reflection imaging and seismic forward modeling.
Compared to convetional modeling methods, modeling by demigration makes efficient use of the time-invariant parameters of a subsurface model and therefore the method is especially well suited for modeling time-lapse scenarios.
This book reviews on the one hand the underlying theory for the mentioned image transformations and focuses on the other hand on the development of a practical tool to perform modeling by demigration. applications of seismic image transformations using both migration and demigration as well as applications of modeling by demigration are presented.
