The best sources of natural gas in the U.S. include shale gas, tight gas, and conventional gas. Shale gas is a form of natural gas that can be extracted from shale rock formations by hydraulic fracturing. Tight gas is a type of shale gas that is trapped within impermeable rock layers. Conventional gas is natural gas that is produced through drilling wells into underground reservoirs.
