Oil is one of the national treasures of great importance in the market, one of the main commodities for the global industry. The oil is used in the form of automobile fuels, for the operation of the thermoelectric power plants and can be used in the manufacture of plastics, synthetic rubbers, paints, solvents, explosives, among others.
Its withdrawal is done in three stages: prospecting, drilling and extraction. The first is carried out from seismic studies where sedimentary basins are located by means of a detailed analysis of soil and basement, through equipment such as gravimeters, Sniffer, seismologists and magnetometers.
The second stage is the drilling, where the oil deposits are discovered and then the markings are executed with GPS coordinates and marker buoys, the offshore. If the research is carried out on the onshore land, the soil is drilled from a first well, considering the oil identification and economic evaluation of the extraction. The holes are executed on land by means of probes and offshore, by sea platforms.
Upon arriving at the third stage, after drilling the well, the oil can flow up to the surface by pressure, decreasing the bombardment of the fuel to the area, which ensures that the material is safely extracted by means of pumps on platforms and other Special equipment.
Currently, Brazil is first among the top 10 countries that have ultra-deep oil reserves. And the largest in the world are found, most of them, in the Middle East. Oil moves the national economy, favoring the enrichment of the country, and consequently, sectors such as health, employment, education, among others.
