Crude Oil

Heavy Crude Oil or extra heavy crude oil is any type of crude oil, which can easily flow. Its density or specific gravity than the light crude oil, because it is a "heavy" is referred to. An API gravity of heavy crude oil is any liquid petroleum that is less than 20, °. [1] light grades to the high viscosity and specific gravity, as well as the physical characteristics that differ between large molecular composition of heavy crudes. Extra heavy oil density is less than 10 ° API (defined by means of an appeal or, equivalently, more than 1 More than 1000 kg/m3 and a specific gravity of over 10,000 centipoises viscosity of a reservoir. [2], [3], a specific gravity greater than 1, the additional of a dense non-aqueous phase liquid heavy crude such as that surrounding circumstances. [citation needed] Gas Exploration Heavy crude oil from oil sand, is closely associated with the natural asphalt. Some petroleum underground due to concentration of less than 10 as extra heavy crude oil, bitumen from oil sands classifying ° API. [Citation needed] extra heavy oil, tar, and other classifications that differ from the label. [Citation needed], they differ in the degree by which they are degraded by bacteria and erosion from the original crude oil. [Citation needed] Often, such as tar, and is solid at ambient conditions of flow. Oil Production North Orinoco River in Venezuela, the world's largest crude oil reserves, the largest of the city, [4], but there are 30 or more countries have reserves of Saudi Arabia, [5], the conventional oil reserves of the same amount.
