While some large industrial, commercial, and electric generation customers receive natural gas directly from high capacity interstate and intrastate pipelines (usually contracted through natural gas marketing companies), most other users receive natural gas from their local gas utility, also called a local distribution company (LDC).
Natural gas is found in coal seams hundreds of metres beneath the earth's surface. Just like conventional natural gas, coal seam gas (CSG) is comprised mostly of methane (CH 4) and is a type of petroleum that was formed from the compressed remains of plants over millions of years.atural gas from coal seams forms part of the gas supply piped into more than one million homes and businesses in NSW for use in everyday cooking, heating and manufacturing. In fact over 30% of the eastern Australian gas network is fed by coal seam gas.
