Abstract: <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> Study from seismic data migrated in the time domain will give us an information of reflector reposition, the problem will show when there is high lateral velocity changing. Pre-Stack Depth Migration can handle the problem of lateral velocity changing. Quality of velocity model must good to run Pre-Stack Depth Migration. <br /> <br /> <br /> <br /> <br /> <br /> <br /> The purpose of this paper is to analyze quality of velocity model which is used for Pre-Stack Depth Migration. To evaluate effect of quality velocity model for Pre-Stack Depth Migration, some synthetic model which is show lateral velocity changing needed to observe. This observation as a checking flow for Pre-Stack Depth Migration. Synthetic process flow is applied to Pre-Stack Depth Migration with real data. Velocity model building pure extracting from velocity analysis of seismic data. Horizon Velocity Analysis (HVA) using stack data from Post-Stack Time Migration as initial subsurface model to build migration velocity model. <br /> <br /> <br /> <br /> <br /> <br /> <br /> Quality of enhancement reflection energy and reflector reposition, compare between Pre-Stack Depth Migration and Pre-Stack Time Migration <br />
