Transcript of Petroleum Petroleum is an oil that is found underground.
Petroleum is a Fossil Fuel.• It was made from
plants and animals.
• The energy in petroleum came from plants and animals.
• That energy came from the sun.
The plants and animals lived
millions of years ago.
They were alive before the dinosaurs!
When they died, they were buried
on the ocean floor.
Over the years, layers of mud
built up, covering the dead plants
and animals.
Heat and pressure from
these layers helped the
remains turn into what we today call crude oil.
Petroleum is Non-Renewable.
The petroleum we use today took millions of years to form.
We can’t make more in a short time.
That’s why we call it a non-renewable energy source.
Today, the oil is found underground.
• Petroleum is buried underground in tiny pockets in rocks.
• The oil is trapped in rocks almost like water is trapped in a wet sponge!
Oil wells pump out the oil and bring it to
the surface.
Some oil wells are
more than two miles
deep!
Oil Well
Off-Shore Well
Oil rigs that can float are used to reach oil beneath the ocean.
Most of these wells are in the Gulf of
Mexico.
We can’t use crude oil as it
comes out of the ground.
We must change it into the fuels that
we can use.
At the refinery, the crude oil is separated into many fuels and
products.
Diesel
Gasoline
Jet Fuel
Propane
Products made from one barrel of crude oil
One barrel of crude oil produces 19.7 gallons of gasoline!
The demand for petroleum-based products is very high.
Petroleum use impacts every
part of our lives!
Americans use more petroleum than any other energy source!
Unfortunately, we use much more oil than we produce.
The U.S. only produces about one-third the amount of oil that we use!
The petroleum industry works hard to protect the environment.
• Oil is drilled and transported as safely as possible, to avoid spills.
• Gasoline has been changed to burn cleaner.
