WebThe two main approaches to seismic imaging produce models for the underground velocities: the first is a process called time migration, which takes seismic data in time coordinates, and produces images and time-migration velocities, which are an averaged velocity of a particular type. The second, depth migration, takes seismic data in depth ... WebThe depth conversion itself is simply a matter of multiplying out the various functions and stacking up the layers to get the depth at each horizon. At this stage a depth converted surface is arrived at, which is optimal but may not tie …

WebDepth conversion, ideally, is an iterative process that begins with proper seismic processing, seismic velocity analysis and study of well data to refine the conversion. … WebStep 1. You slice out the reflector event (in a trace) you want to find the velocity for. Step 2. Take a correlation with the respective trace in other time/depth domain part and find the max correlation time/depth. Here you may assume this time corresponds to the respective depth so you get total travel time. Step 3.
