Natural Gas

It was discovered by a French explorer in 1626, but it was not until 1785 that he knew how to use natural gas. The UK was the first product to commercialize natural gas and it was used to fire fire stations and street lights, but the gas was produced by coal. It is called Edwin Drake. William Hurt excavated the first method of special gas exploration in Fredonia, New York.

Unrelated natural gas, also known as gas well gas, is defined as natural gas that is not in contact with large amounts of crude oil in the reservoir. The EIA believes that most shale gas and all coal seam gas are unrelated natural gas. In 2017, irrelevant natural gas accounted for nearly three quarters of the production in the United States. The proved reserves of unrelated natural gas in the US increased by 95.9 trillion cubic feet in 2017, 36% higher than in 2016. Estimated production of unrelated natural gas in the US increased by 2% from 22.7 trillion cubic feet in 2016 to 23.2 trillion cubic feet in 2017. The largest increase (28.3 trillion cubic feet) of unrelated natural gas proved reserves in 2017 is from Marcellus Shale. The largest decline in unrelated natural gas proved reserves (0.4 trillion cubic feet) in 2017 was in Oklahoma (the proved reserves for total natural gas reserves in Oklahoma increased by 4.2 trillion cubic feet in 2017) .

In 2017, proven natural gas reserves increased for each of the largest eight natural gas reserves in the United States (Figure 3). In all provinces of Pennsylvania, proven natural gas reserves are increasing the greatest, with proven natural gas reserves of 28.1 trillion cubic feet added in Marcellus and Utica shale areas. On December 13, 2017, EQT completed the longest landscape for any business among the Marcellus shale area - Haywood H18 Well in Washington County, Pennsylvania with a horizontal length of 17,400 feet (3 miles or more) It announced. - The company plans to drill over 27,000 feet of 27 Marcellus wells in 2018

Shale gas is natural gas produced by Cher. Since shale matrix permeability is too low to allow the gas to flow in an economical amount, the shale gas allows the gas to flow depending on the fracture. Early shale gas wells were dependent on the natural crushed material through which the gas flows; almost all shale gas wells today require artificially constructed crushed materials by hydraulic crushing. Since 2000, Shale gas has become a major source of natural gas in the United States and Canada. Due to the increase in shale gas production, the United States is currently the world's largest producer of natural gas. After the success of the United States, Shale gas exploration began in Poland, China and South Africa.
