Line 17: − The knowledge required for working with seismic data is built of several layers like an onion. The figure below illustrates the idea. At the heart of the onion are 1-D seismic concepts like wavelet, convolution, traveltime, and reflection coefficient. All this shows up in the next layer, 2-D seismic, plus arrays, offset, dip, and lateral velocity variation. The next layer, 3-D seismic, includes all of 2-D plus azimuth, bins, and the data volume. Finally, 4-D seismic is time-lapse 3-D, which introduces repeatability, fluid flow, and difference volume. − + + +

The knowledge required for working with seismic data is built of several layers like an onion. [[:file:interpreting-seismic-data_fig12-1.png|Figure 1]] illustrates the idea. At the heart of the onion are 1-D seismic concepts like wavelet, convolution, traveltime, and reflection coefficient. All this shows up in the next layer, 2-D seismic, plus arrays, offset, dip, and lateral velocity variation. The next layer, 3-D seismic, includes all of 2-D plus azimuth, bins, and the data volume. Finally, 4-D seismic is time-lapse 3-D, which introduces repeatability, fluid flow, and difference volume.
