Metals in the form of inorganic salts or organo-metallic compounds are present in the crude mixture in tiny amounts. The ratio of different constituents in crude oils varies obviously from one reservoir to another. The exact molecular composition varies widely from formation to formation but the proportion of chemical elements varies over narrow limits and as shown in Table 1.1 1 Table 1.1 the composition by weight of crude oil as chemical element Element Range % Carbon 83-87 Hydrogen 10-14 Nitrogen 0.1 – 4 Oxygen 0.1 – 1.5 Sulfur 0.5-6 Metals
