Extraction and Separation of Crude Oil
Introduction: In this investigation I will use the multimedia science
school programme and the chemistry books to see the formation,
extraction and separation of the crude oil.
Formation of crude oil:

As the materials were washed into the sea, land was formed. The living
material dies then the sand, mud and other materials settle on the top
of the seabed covering the dead living material.

Than the materials are covered and many layers are made and they
become more and more compressed.

Than as layers are made the living materials are squashed in the
middle and they are turned into the oil and also have gas on top of
the oil and also temperature and pressure cause chemical reaction and
changes to oil.
Search History
150 years ago people drilled hole where the oil was out in the surface
so that the can take whatÂ’s in the underground. They also drilled
holes where they think there was oil but sometimes they find and
sometimes they didnÂ’t. Before to many ships were sunk to find oil but
today it is an expensive business to find oil and we also have to do
it with science so that we can find oil.
The rocks contain oil and gas which are hidden from the view by sea or
other rock layers the other thin is that we can not just drill holes
and than see if we are lucky. Before we drill any holes we have to
check the area and this is where geologists, geophysicists and the
scientist came to study the area and the rocks.
The geologists look at the makeup of the rocks. The geophysicists use
the physical characteristics of rocks to find there magnetic and
gravitational properties.
There are many rocks and there are clear differences between them like
the igneous rock or sedimentary or like the sand stone which is
