After well logs and seismic sections have been analyzed for sequences, well log and [[seismic interpretation]]s should be tied together by generating a synthetic seismogram from log information. There are two primary objectives to this step:<ref name=ch21r44 />

The composite synthetic seismic trace from a synthetic seismogram relates depth information from logs to seismic time. The plots of individual wavelets in a synthetic seismogram show how each impedance interface contributes to the individual reflections.
