Three-dimensional visualization technology has been used in the oil industry for many years. However, until recently, it required powerful, expensive computer hardware that generally was not accessible to most geoscientists. More recently, much cheaper and much more powerful PC hardware hasmade 3-D visualization possible on every geoscientist’s desktop.
Seismic interpreters have always needed to visualize, simply because the Earth that we seek to study is three dimensional. The simplest form of visualization that 3-D data provides is one vertical section and one horizontal section, or time slice, side-by-side. This was discussed in Chapter 3. Early extensions of this idea included composite displays of one vertical and one horizontal section spliced together, chair displays and volumetric displays of various kinds, again discussed in Chapter 3. Color is of course vital to visualizing and understanding data, and this is discussed at length in Chapter 2. Visualizing amplitude and structure together is introduced in Chapters 4 and 5, and is further developed in Chapter 8. Visualization of large volumes using voxel display is introduced in Chapter 11. The current chapter extends all these ideas and demonstrates the full power of modern visualization technology to understand, interpret, and integrate seismic data better.
