Just move your mouse over the key points (marked by a number) to understand what it's all about. You can also drag the 'underground' section to view other parts of the natural gas chain.
The story of natural gas is an
ancient one. It all started millions of years ago
when the remains of plants and animals (called
organic material) were buried beneath the earth's
surface under layers of sand and rock. The layers
continues to build up and the organic materials were
buried and deeper.
Very slowly - over millions of
years to be exact! - increasing temperature,
pressure and micro-organisms started to act on the
trapped fossil remains. Just like food in a pressure
cooker, the organic material was slowly 'cooked',
turning them into fossil fuels of various forms such
as coal (solid), oil (liquid) and natural gas
(gaseous). Oil forms first, then as the temperature
and pressure increase at greater depth gas begins to
Natural gas is often found inside
the earth's crust together with oil (petroleum).
Once the area where the crude oil and gas is
established - usually after seismic surveys and
environmental assessments are performed - a drilling
facility is built at the location. Reaching the gas
deposits requires drilling through layers of sand,
silt and rock. he raw gas is then pumped from
underground to the surface and into pipelines.
