Coming directly from oil deposits, natural gas is an extremely versatile fossil fuel, used for various purposes besides being a great source of energy. In Brazil, it is found mainly in the seas of the coast, and the largest reserves located in the states of Rio de Janeiro, Espírito Santo and Bahia.
Basically, natural gas production is done in six steps: exploration, explosion, production and processing in the field, processing, transport and storage and distribution.
- Exploration: Demographic studies are conducted in order to verify the possible occurrence or not of natural gas in region.
- Explosion: This step consists of installing all the infrastructure necessary for the withdrawal of natural gas through the drilling wells.
- Production and Processing in the field: At this stage it is separated from possible "contaminants" that are not of interest in the composition of natural gas, as traces of oil from extraction.
- Processing: it is done in petrochemicals, and at this stage the heavy fractions are removed and the by-products produced originated through natural gas.
- Transportation and storage: Transportation is done through pipelines and storage is not common in Brazil, only in countries climate, aiming to form a stock for harsh winters.
- Distribution: It is made throughout the country and takes the product to the final consumer.
