Yes, dead corpses are transformed into fossil fuels in the absence of oxygen and at high temperatures and pressures. So yes, oil comes from dead humans.
The process by which oil is formed from organic material that is preserved over time with no further input of energy is called "petrogenesis". Oil deposits that result from processes other than petrogenesis are called "fossil fuels". Petroleum geologists are able to tell whether or not a particular rock formation is fossil fuel-containing by using techniques such as magnetic resonance imaging (MRI) and nuclear magnetic resonance (NMR) spectroscopy. These methods cannot distinguish between oil and natural gas, so they must be extracted from the ground before they can be used. Oil spills occur when there is damage to oil reservoirs caused by an act of god or someone else. Spills can happen when heavy rains cause wells to flood or when trucks hit the tanks while transporting oil.
Oil is a mixture of hydrocarbons: molecules composed solely of hydrogen and carbon. The most abundant element found in oil is hydrogen, which makes up more than 75% of its weight. Other common elements include helium, oxygen, nitrogen, phosphorus, sulfur, and some trace amounts of zinc, iron, copper, calcium, and magnesium.
Petroleum (crude oil) is not derived from extinct dinosaurs. It was produced from the remnants of microscopic sea creatures and plants that existed millions of years before the dinosaurs in a marine (water) environment. The heat and pressure from these layers aided the transformation of the leftovers into what we now call petroleum or crude oil.
Oil is a mixture of hydrocarbons of different lengths and degrees of hydrogenation. Oil is sticky because some of its molecules are composed of chains of carbon atoms with hydrogen atoms attached to them. These molecules can stack up tightly together.
Dinosaurs did not have legs made of oil; they used their bones and muscles to walk on land and float in water. However, even though they were not physically moving oil still needs energy to change shape, and dinosaurs lacked the biological machinery for this process so it is presumed that they obtained the necessary energy from burning fat and sugar stores in their bodies.
Sea creatures today use oil for protection and to communicate over long distances. It provides an oily coating which acts as a barrier against predators and allows some species to swim faster by changing the angle at which their tail fins break the surface of the water. Sea animals also use oil to feed their young: females deposit their eggs within the body of another animal (usually a larger one) and the embryo uses its tail to push itself through the mother's skin into the ocean where it feeds on zooplankton.
Petroleum, a fossil fuel, is created when enormous amounts of dead animals, usually zooplankton and algae, are buried beneath sedimentary rock and exposed to extreme heat and pressure. The majority of petroleum has been extracted by oil drilling. Oil is recovered from the ground by using wells drilled into reservoir rocks. The energy in the rock drives the flow of oil out of the rock into the well.
The first step in producing oil is to determine where there are likely to be reservoirs. If you look at a map of the world's oil fields, you will see that they are not distributed uniformly across the planet. They are located in certain geologic settings, which provide conditions favorable for reservoir formation. A good example is the Middle East and North Africa. Here you will find most of the world's oil reserves. Another location with significant quantities of oil is Northern Alaska. There are also large reservoirs of oil under the South China Sea and in the Gulf of Mexico.
Once potential reservoir sites have been identified, an assessment must be made as to whether or not they would be profitable to explore. This requires knowledge of several factors including depth, accessibility, mineral content, and temperature among others. For example, at deep depths (over 3000 feet) it becomes difficult and expensive to extract oil because there is less than one kilo-barrel per barrel available if production rates remain the same as at shallower levels.
Natural gas and oil are not derived from petrified dinosaurs! As a result, they are not fossil fuels. This is a myth. It was then utilized more widely in the early 1900s to persuade people that petroleum, coal, and natural gas were derived from old living organisms, thereby making them natural substances. Today it is known that all three are formed through geologic processes after ancient plants and animals die.
Oil is an organic compound found in the fat cells of animals and plants. Oil has many uses including cooking with oil or butter, making paints, medicines, and vitamins, and as a fuel source. Natural gas is a colorless, odorless gas made up of methane molecules bonded together. It is found in deep underground reservoirs, where it is trapped between layers of rock. The first natural gas wells were dug in Pennsylvania in 1856, but it wasn't until much later that this resource became useful energy. In 1957, the U.S. started using natural gas in place of coal for electricity generation. Since then, its use has grown dramatically. Natural gas is used in almost every aspect of our daily life: as a fuel for cars, trucks, buses, and airplanes; to heat homes during winter months; and to boil water for coffee and tea at work or at school. It also plays a role in manufacturing and seems likely to be needed in large quantities to meet the demands of a growing population.
Today, it is still used in some scientific articles and papers.
In fact, oil and natural gas are products of decayed plants and animals. Oil wells start out as small holes dug into the ground to reach underground reservoirs of oil or natural gas. The oil or gas forces its way through more porous rock until it reaches an opening in the rock where it can escape. As more oil or gas is produced, more holes are drilled to find more reserves.
Oil has been known since ancient times; it was one of the most important commodities in the world for many centuries. Natural gas was first discovered in 1669, but it wasn't until 1816 that the first commercial extraction method was developed. Since then, extensive exploration has revealed vast quantities of oil and natural gas under our feet. We now know that ordinary soil contains hundreds of millions of barrels of oil, while the Earth's mantle is estimated to contain five to 50 billion barrels of oil.
The main source of oil is vegetable matter (including seeds) that decomposes at high temperatures and pressure. Natural gas is a colorless, odorless gas made up of carbon compounds obtained from decaying organic matter.
