| 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.

| 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. Vail<ref name=ch21r44 />) recommends that seismic sequence analysis and well log sequence analysis be started independently so that boundaries be interpreted as objectively as possible before they are tied together by a synthetic seismogram. | | The composite synthetic seismic trace from a synthetic seismogram relates depth information from logs to seismic time.
