        <p>Formed by the fossil fuels of plants and animals, millions and
millions of years ago, <strong>crude oil</strong> is a flammable
substance. It is a mixture of hydrocarbons and other chemical compounds
such as nitrogen, oxygen and sulfur. <strong>crude oil</strong> gets
trapped in the pores of the underground rock and it is extracted to make
it refined. Cosmetics, detergents, gasoline, plastics, paints etc are
made out of <strong>crude oil</strong>. <br><br> Being extracted from
different parts of the world, <strong>crude oil</strong> differs in terms
of its physical properties such as color, viscosity, relative weight etc
after which the oil is heated at a high temperature to separate it from
its impurities and bring it to a usable form. The major <strong>crude
oil</strong> producing countries are Mexico, United States, Iran,
Nigeria, Kuwait, Saudi Arabia and China. Among these countries, Saudi
Arabia is the world's major and leading producer of <strong>crude
oil</strong>. Due to the advancement in technology and various other
reasons, demand for <strong>crude oil</strong> has increased and it is
being consumed at a high rate in different parts of the world. The major
oil consuming country is the United States of America followed by China,
Japan, India, Germany, and France, etc. <br><br> Even though oil is
consumed at a high rate globally, not all countries produce it. Countries
like Italy, France, Spain and India import <strong>crude oil</strong>
from the major <strong>crude oil</strong> producing countries to meet the
increasing demand of oil consumption. Due to the huge demand in
<strong>crude oil</strong>, it is estimated that the oil reserves will
get depleted after few years. Hence scientists are trying to figure out
an alternative to overcome the global energy crisis. The oils can be
light and volatile liquids or heavy. The light and volatile oils are
toxic to animals and plants .Non sticky oils are less toxic. Heavy oils
are sticky and black in color. There are also asphaltic base, paraffin
base and mixed base oils. <br><br> <strong>Types of crude oil and
Classifications of crude oil</strong> <br><br> There are many different
<strong>types of crude oil</strong> and <strong>Classifications of crude
oil</strong> is based on the geographical locations, sulfur content and
relative weight but the major classification is done based on the
location, as the oil comes from various parts of the world and they
differ in their characteristics. The American Petroleum Institute or the
API provides a basis to measure the density of the oil. If the presence
of sulfur is low in the <strong>crude oil</strong>, it is termed as
'sweet' and if the oil has high sulfur content then it is termed as
'sour'. Based on the geographical classification, the various benchmarks
are North Sea crudes, United State crudes, West African crudes and
Persian Gulf crudes. The North Sea crudes comprise of Brent, Osberg,
Forties, North Sea basket etc. Brent Sweet Light crude is light but not
as light as the West Texas Intermediate (WTI). Brent crude is suitable
for the production of gasoline. The sulfur level is 0.36% whereas the API
gravity is around 38.5 degrees for the North Sea crudes. <br><br> The
Next benchmark of <strong>crude oil</strong> which is the OPEC Reference
basket or the West African crudes has API gravity around 35 degrees and
sulfur level of 0.2%. Bonny light, Escravos, Forcados and more fall under
this benchmark. The Persian Gulf crude includes Dubai, Arab and Qatar.
API gravity around 37 degrees and 1.08% of sulfur level are the measures.
The United States Crude comprises of West Texas Intermediate (WTI), West
Texas Sour (WTS), Light Louisiana Sweet (LLS) and much more. The sulfur
content is 0.24% and the API gravity is 39.6 degrees. The WTI is ideal
for the production of gasoline due to its low sulfur content and it is
lighter than Brent crude. <br><br> For more information and details on
