Tiny sea plants and animals died
and buried on the ocean floor.
Deeper and deeper. The
enormous pressure and
heat turn them into oil
and gas.
They didn’t completely
decompose because there
wasn’t enough oxygen in the
water. Over time, they were
covered by layers of sediments
and rocks.
Over millions of years, the
remainds where buried
Today, we drill down throught
the layers of sedimentary rock
that contains oil and gas
deposit.

OIL IS A MIXTURE OF DIFFERENT
HYDROCARBON MOLECULES. AND
WHEN WE SEPARATE THEM WE OBTAIN
DIFFERENT PRODUCTS.
To separete molecules of different
lenghts, we pass oil throught a HOT
PIPE. As the OIL GETS HOT, the
LIGHTER MOLECULES EVAPORATE
and exit the pipe. As the OIL GETS
HOTTER, the HEAVIER MOLECULES
EVAPORATE and exit the pipe.
