THE PETROLEUM

T H E   P E T R O L E U M

Oil is a homogeneous mixture of organic compounds, primarily hydrocarbons insoluble in water. 

Also known simply as crude oil or crude oil. 

It occurs in the interior of the Earth, transforming the organic matter accumulated in sediments in the geologic past and can accumulate in natural geological traps, from which it is extracted by drilling wells.

It is common to measure the volumes of liquid petroleum in barrels (42 US gallons, equivalent to 158.987294928 liters), and the volume of gas in cubic feet (equivalent to 28.316846592 liters); in other regions both volumes are measured in cubic meters.
