Natural gas is a form of energy that is known for many centuries but its systematic usage dates back to only a few years after World War II.
Natural gas is a mixture of light hydrocarbons in a gaseous Itate.
It´s principal component is methane (CH4) in a proportion of approximately 80 to 95%.
Formed over millions of years, from organic deposits in the bottom of the ocean and continents forming wells that may or may not be associated with petroleum. It is extracted by perforations in the ground in the same way as petroleum.
Gas wells are found in certain fields that are detected by various sophisticated cientific methods which are found in the ocean or on solid ground.
Natural gas is a primary energy because it originated directly from nature and it is used without heing transformed in any way.
A secondary energy results from the transformation of other energies for example propane and butane which are the major components of GLP.
Natural gas with a correct operation of the burners produces an energy source with components such as water and carbon dioxide with very little contamination.
