New Albany Shale

It is predominantly brownish to grayish black, finely layered, pyrite, carbonaceous shale (Lineback 1980). Grassy Creek Shale is one of the most organic carbon cities of New Albany Group (Lineback 1980). These thick black shales are located in the middle of the Illinois Basin (Lineback 1980). The thickness of the glass creek shale is a maximum of 160 feet, and it is inclined in the lateral direction northwest afterward (Lineback 1980). In Indiana State, Grassy Creek shale is equivalent to Morgan Trail, Camp Run, Clegg Creek (Lineback 1980).

Hydraulic fracturing of energy sources is underway in the United States. There are several shales in the county, including the Mancos shale of Utah and Colorado, the New Albany shale of Illinois and Kentucky, and the largest shale Marcellus shale in the country. Mercerous shale extends to Pennsylvania, Ohio, New York, West Virginia, Kentucky, and Virginia. The majority of the Marcellus shale is in New York and Pennsylvania where shale begins to decompose and natural gas can flow into new wells.

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.
