Value chain 
 

From the formations of reserves to sales to final clients, natural gas undergoes a complex set of processes and activities. These vary according to the distance and available means of transportation.

Natural gas is transported to final clients by pipeline or by ship for longer distances.
 
When configuring the natural gas value chain, a high-pressure pipeline connection close to the processing and marketing centres is the most important factor.
 
Close to the consumption centres, natural gas is marketed through a complex network of thousands of kilometres that cover the main consumption areas, namely industrial and residential customers.

Natural gas value chain

  

Transportation through pipelines, underground or underwater, is connected to a complex system of pipes and control systems that guarantee the safety of this activity.

The value chain of liquefied natural gas


Transporting natural gas by sea requires the gas to be cooled (-160º) so that it maintains its liquid state (liquefied natural gas) under a pressure slightly higher than the atmospheric pressure. At the destination terminals, gas is transformed again into the gas state to be injected into the distribution network.
