The demand curves for competitive firms, however, are almost perfectly elastic because no matter how these firms change their production, in a perfectly competitive economy, there are so many firms out there that its production will not affect anything.onopolistic competition, because there are so many relatively weak firms, there are no barriers to entry. Companies can enter the market relatively easily (although, of course, not as perfectly easy as in perfect competition). This makes for a long-term equilibrium competition of no profit.
How Is Natural Gas Produced. Natural gas is found in oil fields, natural-gas fields and coal beds. Since natural gas isn't a pure product, it needs to undergo processing before it can be used as consumer fuel. The gas is extracted from a field using a decompression process called retrograde condensation.
Natural gas. Natural gas is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium. It is formed when layers of decomposing plant and animal matter are exposed to intense heat and pressure under the surface of the Earth over millions of years. The energy that the plants originally obtained from the sun is stored in the form of chemic
