Natural gas futures hit nearly $15 in 2005. Chemical and metals manufacturers were shutting U.S. factories and moving overseas, where gas was abundant and cheaper. Farmers in need of fertilizer were turning to inexpensive imports from Canada, Trinidad and Asia. But over the next few years, drillers perfected methods first tried in 1981 that now allow them to profitably extract gas trapped in shale formations
-- layers of fine-grained rock that in some cases have trapped ancient organic matter that has cooked into oil and natural gas. Engineers combined the ability to drill horizontally into shale with a technique called hydraulic fracturing. Millions of gallons of water, sand and chemicals are pumped into wells to break rock and create escape routes for the gas. In doing so they unlocked natural gas deposits deep underground across the East, South and Midwest that are large enough to supply the U.S. for decades. This eventually turned the shortage into a glut, and reversed the fortunes of some industries. An ammonia plant owned by CF Industries in Donaldsville, La., that was shuttered by its former owner in 2004 is running again. Steel maker Nucor Corp. is building a factory in Louisiana; Shell Oil Co. is planning a petrochemical plant in Appalachia; and Dow Chemical is building a type of chemical feedstock plant it hasn't built in the U.S. since 1995. "A whole slice of American industry is benefiting," says Steve Wilson, the CEO of CF Industries, which makes ammonia and other fertilizer ingredients. CF Industries, which is based in Deerfield, Ill., has seen its daily natural gas costs fall from $6 million to $2 million over the past few years. The company is planning to spend more than $1 billion expanding its U.S. plants. While industrial customers are betting on low prices for years to come, things could change if demand increases sharply because of extreme weather or faster-than-expected economic growth, or if the U.S. begins exporting gas. It's also possible that natural gas drilling could be curtailed by environmental regulations designed to protect drinking water from hydraulic fracturing. Legislators in New York and New Jersey have banned hydraulic fracturing temporarily, and the Environmental Protection Agency is studying it and may propose national regulations. The most likely near-term scenario is that prices keep falling, according to Rusty Braziel, an analyst at Bentek Energy. "This ain't the bottom," he says.
