Overview of Natural Gas Resources 1 3

5 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

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.

sft 3 ( 1 MSCF ) of Natural Gas is equivalent to : 52 kg of (indigenous) Coal 28 liters of Kerosene barrel of Crude Oil (petroleum) 285 kwh of Electricity tone of Furnace Oil 21 kg of LPG 58 kg of Wood Generally

FORMATION OF NATURAL GAS Anticline TrapFault Trap

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

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 with the gas 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 of need is uneconomic Non Associated NG Associated NG Natural gas sources
