Future natural gas supply

Natural gas supplies nearly one-third of the nation's total energy and is of particular importance to the household-commercial and industrial sectors. Despite relatively large conventional reserves of 216 Tcf and inferred reserves of nearly 200 Tcf, annual production decreases yearly and not only fails to meet annual demand but also does not meet peak loads, which leads to winter curtailments. The most significant indicator is the declining ratio of reserve additions to production. Apparently intrastate reserves additions far outstrip interstate, suggesting a real supply sensitivity to price. Modest additions to supply now come from synthetic natural gas (SNG) derived from light hydrocarbon liquids and LNG. Future supplies may come from increases in overland imports from Mexico and the Arctic, continued S. Canada imports, and SNG derived from coal. Mostly untried gas sources exist; these include underground coal gasification, methane occluded in coal seams, gas hydrates in the Arctic and in the deep-sea basins, and gas from biomass, landfills, low-permeability sandstones and shales, and geopressured reservoirs.
