Introduction:
Natural Gas is a vital component of the world's supply of energy. It is one
of the cleanest, safest, and most useful of all energy sources.
What is Natural Gas:
Natural gas is a combustible mixture of hydrocarbon gases( from CH4 to
C8H18”OCTANE) consisting essentially of METHANE ,other hydrocarbons
and non Hydrocarbon Gases in gaseous state ,which is extracted from the
subsurface of the earth in its natural state ,separately or together with
liquid hydrocarbons

Globally, natural gas has a proved reserves life index of 64 years. The IEA (2012)
estimates that there are nearly 404 trillion cubic meters (tcm) (14,285 trillion cubic feet (tcf))
of remaining recoverable resources (including all resource categories) of conventional gas
worldwide, a value that is equivalent to almost 130 years of production at 2011 rates.

1000 sft3 ( 1 MSCF ) of Natural Gas is equivalent to :
52 kg of (indigenous) Coal
28 liters of Kerosene
0.168 barrel of Crude Oil (petroleum)
285 kwh of Electricity
0.024 tone of Furnace Oil
21 kg of LPG
58 kg of Wood
Generally
16. NATURAL GAS
• Natural gas resources
• Crude oil wells with a gas cap above the crude oil trap
or gas dissolved in the oil produce associated gas
• Gas wells and condensate wells are gas sources that
contain little to no crude oil and are called non-
associated gas
• Condensate wells that contain heavier forms of natural
gas (pentane) can also produce low weight
hydrocarbons in the gas product
20. Gas produced from gas reservoirs,
Comes naturally at high pressure, enough to propel
through processing and transmission to point of use.
may or may not be condensate production together

Gas produced with crude oil.
Comes at low pressure. Requires compression to propel
through processing and transmission.
Often flared when processing and transmission to point
