Theory of differential offset continuation |

The simplest and most important example is the case of a plane dipping
reflector. Putting the origin of the axis at the intersection of
the reflector plane with the surface, we can express the reflection
traveltime after NMO in the form

According to equations (28-29), the time rays in this case are defined by

The geometry of the OC transformation is shown in Figure 3.

the reflection traveltime curves in the OC process: the case of a
plane dipping reflector. Left: Time coordinate before the NMO
correction. Right: Time coordinate after NMO. The solid lines
indicate traveltime curves at different common-offset sections; the
dashed lines indicate time rays.
