Natural gas is predominately composed of methane (CH 4 ). Some of the gases that are produced along with methane, such as butane and propane (by-products), are separated and cleaned at a gas processing plant. The by-products, once removed, are used in a number of ways. For example, propane can be used for cooking on gas grills.

Non-associated gas is found without accompanying oil. A reservoir of non-associated gas could arise from gas migrating to a different location than that to which oil migrated, or from formation of gas in the gas window, i.e. without oil.
