Figure 2: Well to seismic tie for PS data. (a) S-velocity well log curve, (b) the measured density curve in red, the estimated pseudo density curve in blue, (c) re ectivity derived from these two curves. (d) The blue traces are the synthetic traces derived from the re ectivity and using the wavelet shown on the top right. The red seismic traces are the PS data at the location of the well. Most of the re ection events seem to correlate well on the blue and the red traces, except at the locations marked with yellow arrows. (e) Re ectivity calculated from the pseudo density and S-velocity, which in turn is used for generating the blue synthetic traces in (f). The PS seismic data is shown in (g). Notice the differences between the re ection amplitudes indicated with the yellow arrows. The correlation with pseudo density re ectivity seems to be better as indicated by the correlation coef cient increase from 76 percent with (d) and 78 percent in (f).
