FIGURE 8-1. World distribution of petroleum resources and reserves. [Source: W. Fulkerson et al., Scientific American, September 1990, p. 129.] Most of the world's petroleum is to be found in the Middle East, as shown in Figure 8-1 and in more detail in Figure 8-2. Figure 8-1 also illustrates the fact that the world reserves
