FIGURE 4.6 The alternative usage of federally owned crude helium as a source of last resort. The colored bars show the helium capacity of the various potential sources of helium; the green line shows actual (2005-2008) and estimated (2009-2020) worldwide demand.

FIGURE 4.7 Amount of crude helium in the Bush Dome Reservoir under the current scenario (Case A), where 2.1 Bcf of helium is withdrawn from the reservoir each year, compared with the amount under the alternative scenario (Case B), in which the Bush Dome Reservoir is treated as a source of last resort, drawn on only to meet the needs of helium users not satisfied by other sources.
