ABSTRACT
A comprehensive analysis of the role of natural gas in meeting energy requirements must take into account several basic points:
1. Natural gas is an extremely useful and desirable fuel. 2. Natural gas competes with other fuels. 3. Natural gas and liquid hydrocarbons (such as crude oil, butane, and propane) are developed and
produced jointly. 4. Natural gas virtually displaced manufactured gas because it was cheaper and better. 5. Changing demands affect the relative prices of joint products.
