How can we generate a synthetic seismogram?
January 14, 2009 10:28AM
The procedure to create a synthetic seismogram is as follows:
- Multiply the velocity (calculated from the sonic log) and density logs to generate an acoustic impedance (AI) log. When a density log is not available, the densities can be calculated from the velocities with Gardner's rule: the density is proportional to the ¼ power of the P-wave velocity. - Calculate from the AI log the reflection coefficients (using Zoeppritz' equation) - Determine the wavelet from the seismic data - Convolve the wavelet with the reflection coefficient trace to generate the synthetic trace
