The exploited reservoirs are between 600 and 8000 meters deep. But there are deeper deposits
In 2009, it was discovered in the Gulf of Mexico as an oil field 1260 meters of water and reaching 10,600 meters deep. The presence of oil at such a depth was unimaginable ago thirties. How far in do you find
The oil resulting from the degradation of organic waste, mostly of vegetable origin, under the action of heat. But the temperature increases with depth, 30 ° C per kilometer on average. Buried in a sedimentary rock (the "bedrock"), organic debris is first transformed into a carbonaceous solid called kerogen, which coal is a variety, then give either oil and some gas (between 80 ° C and 150 ° C), or just gas (above 150 ° C). We deduce that the
