Petrol and diesel sea under the earth !!

[suntrack2]

when these two things found very firstly ? to whom ? (how these two items evolved?)

uptill this is going smoothly, the fuel consumption is just going on rapidly,but how these two things formed? is it due to big mixing in the present sea(s), or both things were found at the bottom of the sea due to its density?

both fuel modes are great one, are they formed during earth was taking shape?, ir these two things comes after the earth was formed solidly. these two things is an extraction of chemical process under the water? or a big rock was grind in the sea and these two things came out?

lot of questions are there, today we are looking these things are how much important.

do you think that petrol and diesel can only found under the sea and under the land(if we dig dipper) !!

Or there is a pacific like under ground sea of petrol and diesel present!!, and the oil is resting in it's bottom?

First, there's only petrol (petroleum) and natural gas. Diesel is a fuel derived from petrol, while natural gas is a fairly complex mixture of primarily methane (result of biological decomposition) but with ethane, propane, butane, and pentane, mixed in with some other non-combustible gases.

Second, petrol, like natural gas and coal, is a fossil fuel. All fossil fuels are the result of biological decay. Both animals and plants are laden with a rich variety of fats and oils, and fossil fuels are the result of being under heat and pressure in the Earth.

Fossil fuels of all types are found under both land and sea.

Here's wikipedia's (http://en.wikipedia.org/wiki/Petroleum#Formation) explanation, and it seems short but good.
Geologists view crude oil and natural gas as the product of compression and heating of ancient organic materials (i.e. kerogen) over geological time. Formation of petroleum occurs from hydrocarbon pyrolysis, in a variety of mostly endothermic reactions at high temperature and/or pressure.[9] Today's oil formed from the preserved remains of prehistoric zooplankton and algae, which had settled to a sea or lake bottom in large quantities under anoxic conditions (the remains of prehistoric terrestrial plants, on the other hand, tended to form coal). Over geological time the organic matter mixed with mud, and was buried under heavy layers of sediment resulting in high levels of heat and pressure (known as diagenesis). This caused the organic matter to chemically change, first into a waxy material known as kerogen which is found in various oil shales around the world, and then with more heat into liquid and gaseous hydrocarbons in a process known as catagenesis.


As mugs said, refiners take crude oil and process it into the various fractions that we use: gasoline, diesel, kerosene, asphalt, etc., etc.

OP asks when these things were first found. There exist accessible asphalt deposits and oil seeps at the surface, which were almost certainly discovered by man in prehistory. They were certainly in common use by those early civilisations which had access to them, notably in the form of asphalt (bitumen), which was comnonly available in the Middle East, and used for mortar, waterproofing and mummification.

The earliest known oil wells were in China, at least as early as 347 CE. Large scale industrial exploitation of mineral oils took off only in the later years of the 19th century, following the discovery of the possibility of extracting kerosene first from coal (1846) and quickly after that it was found more easily got from petroleum (1852). The first off-shore production of oil began off the coast of Summerland, California in 1897.

In the standard theory of the geological origin of petroleum, the sea plays an important part. Widespread anoxic conditions in the oceans prevailing at certain periods in geological time allowed large quantities of organic matter to be preserved there, rather than recycled by life as currently happens in most places.

...the roots of anti-oil protests in the Santa Barbara Channel date back to the installation of oil platforms off the coast of Summerland, long before the [1969, 3 million gallon] Platform A blowout. “They started offshore oil drilling in the 1890s, and within a year or two, there were anti-oil protests, there were newspaper editorials and letters to the editor about this horrible, foul, evil, ugly stuff [happening] on the beaches and offshore,” Smith said...
