WebWEDGE MODEL Calculating seismic reflection responses across a bed that thins continuously is a useful modeling technique for developing the principles of thin-bed interpretation that will be emphasized in this module. Such a wedge model is displayed below. Figure 3. WebThe wedge model used to generate the synthetic seismograms. The variation in the velocity is shown as well as the mean trend in wedge thickness (white dotted line). Figure 2. The zero-offset synthetic seismogram data set. In this wedge, with a mean velocity of 2500 m/s, a 30 Hz signal has a wavelength of approximately 83 m.
