Figure F51. Comparison figure for synthetic seismogram generation for Hole C0001D. Source wavelet is 256 ms long with a 4 ms lag that was extracted at the borehole using a deterministic algorithm based on the power spectrum. A. Check shot allowing conversion from time to depth. TWT = two-way traveltime. B. Calibrated sonic log in slowness (DT). C. Spliced density log with real-time data above 192 m LWD depth below seafloor (LSF) and pseudodensity data to total depth. RHOB* = spliced bulk density measurement. D. Five identical traces showing the computed synthetic seismogram (Synth.). E. Reflection coefficients (Refl. coeff.) calculated from the sonic and density values at each depth. F. Source wavelet. G. Ten seismic traces on either side of the borehole from Inline 2680 of the three-dimensional volume. H. Gamma ray (GR) log.
