Table 1 shows the gas-field-size requirements and typical world-scale plant sizes for some of the gas utilization options. The gas-field-size requirements are based on a single-train plant with a 20-year life. A combination of different gas monetization options also can be used depending on the available gas reserves. Table 2 compares the total market size for the different products for year 2001. Figure 1 depicts the impact of an additional 1,000 MMscf/D of gas on the product market.
