Americans use a lot of energy. In fact, the is the second largest consumer of energy in the world, and the seventh largest per capita. Most energy in the U.S. comes from fossil fuels.

The gas sources. Ohio has two such shale deposits: the chemicals they contain — and carbon Marcellus and Utica shales. The Utica shale formed — form petroleum, or natural gas. These are during the Ordovician period (480–442 million years typically burned to provide energy.1 ago) and the Marcellus shale formed during the Devonian period (417–354 million years ago).

Usually, a system of pipeline is installed to move the oil and gas to refineries. There are two types of natural gas. “Dry” gas is primarily methane and “wet” gas contains oil and natural gas such as ethane, pentane, and butane, in addition to methane. Much of the Ohio shale gas is expected to be wet gas. As such, it needs to be sent to a refinery, such as a fractionator or cracker, where the different components are separated and sent to the various industries that use them.

After a well is drilled, the shale is hydraulically fractured in a process commonly called fracking. Fracking involves pressurizing the wells up to 15,000 pounds per square inch and injecting water, sand, and a variety of other chemicals to break the shale and create channels that allow the gas and oil to escape. Fracking a horizontal well can use five million gallons of water or more, 20 percent of which is returned to the surface. The water, sand and chemical mixture that returns is called flow back.
