1. Good Migration Enhances Resolution
SLIDE 17
Here is a seismic line with two types of migration:
On the left a standard (fast,cheap) migration algorithm was used
On the right, a more sophisticated (more time, money, people-hours) algorithm was used
Note the fault on each image
The termination of reflections are much sharper on the right; the fault can be more precisely drawn
On the left the reflection terminations are more “smeared” since the lateral resolution is much lower
