Answer 2

Difference Between Associated and Natural Gas

Associated Gas: Associated gas is found in oil fields and is produced along with crude oil. It is often dissolved in the oil at reservoir conditions and is released as a gas when the pressure is reduced during production. Associated gas can also be found in gas caps above the oil zone in a reservoir. It is typically rich in methane and is often processed to remove impurities before being used.

Natural Gas: Natural gas, on the other hand, is found in reservoirs separate from oil fields. It consists mainly of methane, but can also contain small amounts of other hydrocarbons, such as ethane, propane, and butane, as well as small amounts of nitrogen, carbon dioxide, hydrogen sulfide, and rare gases.

Differences: The primary difference between associated and natural gas lies in their association with oil. Associated gas is found in oil fields and is produced along with crude oil, while natural gas is found in separate reservoirs. Additionally, associated gas is often processed to remove impurities, while natural gas may contain a wider range of hydrocarbons and impurities.
