Interval zero-offset two-way travel time
WebIn a constant velocity medium V, the offset travel time T may be used to define the length of the raypath, i.e. S-G i = VT, and the corresponding half distance by CMP-N = VT/2. Similarly the length of the zero-offset raypath is CMP-R 0 = VT dm /2. These two times are plotted on the trace below CMP with the appropriate time scale.

WebJan 1, 2014 · Then the recording time for an event from an exploding reflector is the same as the two-way zero-offset reflection time, with the actual velocity, from the same reflector. This thought experiment (Loewenthal et al., 1976 ) provides the basis for a poststack migration imaging principle, breaking migration into two parts: downward continuation … WebThe offset at the nearest downstream intersection is determined by adding the travel time to the offset of the adjacent upstream intersection. The travel time is estimated by dividing distance between the intersections by the average speed on the link. This process continues until the offsets of all intersections in the group have been determined.
