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.

WebTo determine this level, depth convert 1s level (time 2dgrid) and observe difference to known level of original datum (400m). eg Z = 400 - Z; should be around 1900m. - shift seismic up by one second to avoid negative times and to align with vel. model. - Use 2dgrid as floating datum for time depth conversion of seismic. include but notWebFeb 28, 2024 · In equation (4.2b) in part (b) is a time difference between two rays generated by the same source and is therefore a time interval due to the dip of the bed and the fact that the two receivers are a distance apart.
