Synthetic seismograms, synthetic sonic logs, and synthetic core

Laurence R. Lines, Mahbub Alam

In geophysics, we often model or “synthesize” measurements in order to enhance our interpretation of geophysical data. Synthetic seismograms often utilize sonic and density logs to produce impedance profiles in order to model seismograms in order for us to pick reflections on seismic data. Synthetic sonic logs, as initially described by Lindseth (1979), utilize seismic data in order to estimate acoustical impedance. Synthetic core uses well log data and geological templates of depositional features in a field to produce rock properties.
