Fig. 6. Seismic line from 1989 survey with revised 3-D time migration and reduced velocity field, based on 260-1 and 1ST1 checkshot velocities. Note better positioning of amplitude anomaly. However, the steeply dipping reflections from top and base of salt are now undermigrated. Note amplitude increase caused by constructive interference where the reservoir intersects undermigrated, salt-base reflector. |
