Crude oils are extracted by fractioning crude oil in a fractioning tower. They are fractioned by heating to boiling point and rising up the tower where they condensate and come out in another form.
By using Fractional Distillation.
Waxes are separated from crude oils in a process called solvent dewaxing. A limited number of crude oils are suitable for processing in the lube oil refineries that run this process. These crude oils must have a high wax content in the original crude, resulting in a high pour point, making these types of crude oils difficult to extract and process in other refinery units. See the excellent link below entitled: "The Evolution of Base Oil Technology"
Crude oils
This is the possibility to extract crude oil for long time.
It comes from underground and we extract it by drilling a hole then by pumping it out of the ground
yes
you extract them by drilling wells
viscosity. very viscose oils are considered "heavy", oils of low viscosity are considered "light". Oils with little sulfur are considered "sweet", oils with lots of sulfur are considered "sour". The most valuable crude oil is "light sweet".

To get lots of different oils from the main crude oil you must put it into a fractional distilaltion chamber.

the Melting point depends on different types of Crude oil.. Crude oils are of different types ..so there is no specific Boiling point
