Natural gas
Natural gas is a mixture of hydrogen and carbon compounds and small amounts of hydrocarbon compounds in the gas phase or in solution with the crude oil is in the deposits.
Thegas molecule is composed of one carbon atom and four hydrogen atoms, which are represented by the formula (CH4) as you can see in this picture.
Many natural gas hydrocarbons are saturated, whichmeans that each carbon atom is bonded to four hydrogen.
These are known as alkanes, and aliphatic paraffins.

Natoral gas extraction
The natural gas is extracted by expansion, this means that thesame gas pressure in the tanks of the rocks, the pulse produced fluids into the wellbore and then climb the outside.

Pressure is natural gas production from the well, gradually decrease over theexploitation of the deposit, however life can be extended by using compressors for imparting strength to the gas found underground and help you to get to the pipeline .

Natural gastreatment
Which removes items which can be water, acidic compounds such as carbon dioxide and hydrogen sulfide, nitrogen, helium, and other solids and impurities, which could not be eliminatedpipelines corrode and damage the environment
The gas, before being transported and used commercially must be purified and have passed all quality standards required by carriers and consumers.
Duringtreatment the gas is subjected to extraction and fractionation processes to separate components and methane gas available for transportation and distribution under established quality standards.

Theseparate components in this process, such as ethane, propane, butane and pentane, are later used individually as products traded on the market, thanks to its wide range of applications, among which wecan mention the enhanced recovery of crude oil, the feedstock for refineries, petrochemical plants and energy use.
