| Summary: | Geologic models like point difractor, high velocity layer, and dipping layer, can produce phenomena of seismic such as bow tie, and difraction. That can make miss interpretation of seismic section. Migration is one kind solution to minimum this error. In this final project has used Reverse Time Migration Method to result Poststack Time Migration.<p> <br />

Synthetics seismogram data consist vertical and horizontal components record, result from forward modelling with finite difference scheme. Processing of vertical component data by doing with standard seismic data processing. Horizontal component data is processed with prosedur Asymptotic Conversion Point (ACP) Binning, and construction P-S data velocity, uses value Vp/Vs ratio and velocity analysis of vertical component.<p> <br />

Extrapolation time reverse from vertical and horizontal components record, run respectively with constant phase shift from record (t=tmax) to initial time (t=0). Migration of synthetics seismogram Marmousi model produce good image for vertical component. On horizontal component, the use of variation value Vp/Vs ratio is to show horizontal and vertical structure at this model. |
