How Natural Gas is Delivered Natural gas is found in the earth and is drilled for just like oil and water. All of Springfield s natural gas comes from Texas, Louisiana, and the Gulf of Mexico.
Natural gas comes from two types of wells.
Non-associated gas wells and associated gas wells. In associated wells, natural gas is found in combination with oil. When natural gas leaves an associated well it goes through a separator, to separate the oil from the gas, on its way to the processing plant. Gas from non-associated wells goes through a cleaner on its way to the processing plant. The processing plant separates the impurities, liquid products, such as propane, and other gaseous products.
