This compression process produced gaseous hydrocarbons that expanded and formed pockets and fissures in the rock — formations that now hold natural gas.
The volume will only get larger, too: oil and gas producers use at least 7.5 million liters of water per well to fracture subterranean formations and release entrapped hydrocarbon fuels, a practice that has grown in the U.S. by at least 48 percent per year in the last five years, according to the Energy Information Administration.
