Natural gas basins are large underground areas where natural gas is found in large quantities. These basins are typically located in sedimentary rock formations and are often found in areas with high concentrations of oil and gas. Natural gas basins are often divided into two categories: conventional and unconventional. Conventional natural gas basins are those that are easily accessible and can be extracted using traditional methods. Unconventional natural gas basins are those that require more advanced extraction techniques, such as hydraulic fracturing.
