Reliability Of Migration Velocity Model: Comparison Study Of Conventional And CRS Semblance Supergather Quality
Velocity is vital part in processing. The problem will be shown when there is curve, dip and lateral variation of velocity by reflector. Asssume reflector as a point is not optimal to solve the problem. CRS (Common Reflection Surface) method, consider curved and dipped reflector on its process. <...

| Summary: | Velocity is vital part in processing. The problem will be shown when there is curve, dip and lateral variation of velocity by reflector. Asssume reflector as a point is not optimal to solve the problem. CRS (Common Reflection Surface) method, consider curved and dipped reflector on its process. <br />

On this paper, low dominant frequency used in mermousi-2 data. Velocity analysis uses CRS semblance make picking velocity easier, its cause a trend signal of reflector more focus and has been separate signal and multiple noise. <br />

Pre-stack depth migration is used to evaluate quality of velocity model. Migration velocity built from Horizontal Velocity Analysis (HVA) with migration time domain section as a guide. |
