How i think oil was formed in the earth

Recommended Posts

Hundred of millions of years ago. when our planet was already formed. The planet was completely covered with water. Oceans were not as deep as they are today, but only a few hundred feet deep but thousand of miles long.


As time passed, green sea moss began to grow in the shallow areas.


Since there was no sea life, like fishes or other type of sea life, to eat or disturb the moss, it grew very thick.


After a while, this moss broke away and slid down in the deepest vallies. As more time passes this moss will be hunded of feet deep and thousands of miles long.


The moss at the lower depth start to decompose into a black slimy goo, as more moss come on top, great pressure of moss and water cause cracks in the botton of the vallies where this thick slimey goo began to fill the empty hollows in the earth where it was "cooked" by the heat and roation of the earth for a long period of time.


This is how I think crude oil was formed in the earth and not by decomposing trees and animals.

Hello University,


I didn't read your post too closely, but it seems to be valid. I just want to note that it's more than just moss, but you seem to have the basic idea correct. Organisms die, layer, and decompose, and under pressure form oil.



Here is a wonderful program on the subject. Maybe you'll enjoy it as much as I did:





All three parts, as well as the interviews, are fantastic. Enjoy. :)

"The Origins of Oil

Petroleum in ancient times was called bitumen, and mankind for centuries was not at all sure what bitumen was made of or where it came from. Two ideas developed in ancient times to explain the composition and origin of bitumen. One held that bitumen was inorganic and bore no relation to living things, whereas the other theorized that it somehow formed from once-living plants or animals.

Leo Lesqueroux, considered the father of paleobotany, claimed in 1866 that petroleum in Pennsylvania formed from marine algae in Devonian shales much the same way that coal forms from land plants. Later, Anderson and Arnold convincingly argued in a 1907 bulletin of the U.S. Geological Survey that the only possible source for oils from Santa Maria field in California was microscopic fossil plants, called diatoms. Another bulletin by Clarke in 1916 demonstrated that the Santa Maria oils were chemically similar to the organic remains of diatoms.

There is agreement among most geologists today that crude oil was formed over million of years from the remains of tiny aquatic plants and animals. This oil was formed from organic matter that is either "cooked" deep within the earth.

Kerogen is the name given to the fossil organic matter. Kerogen occurring in many areas is derived mainly from diatoms, one-celled planktonic plants with microscopic shells of silica. Other types of plankton & sometimes bacteria that feed on decaying plankton, make up most of the kerogen in many of the oil source rocks.

Most crude oil was thus formed from planktons, one-celled plants and animals, which floated on the surfaces of ancient oceans. As these organisms died, they settled to the ocean floor and were covered with mud. If the mud did not contain enough oxygen for the soft parts of these organisms to decay, then the organic material was converted into kerogen. Some kerogen may later be converted into oil.

Some oils also formed from non-marine algae and bacteria which grew in ancient lakes.

In summary, most crude oil formed from microscopic plants and animals – prominent among them being algae - that died millions of years ago. With deeper burial, sufficient time and temperature, the soft parts of these organisms, were slowly converted to oil over millions of years"

If I may I would like to say that there is another school of thought, oil, coal and other hydrocarbons found int the earth are not biology reworked by geology but are actually geology reworked by biology. Hydrocarbons were deposited with the earth as it formed from material similar to hydrocarbon rich meteorites called carboniferous chonderites, this hydrocarbon material is reworked by biology into Oil natural gas and coal, The observed phenomenon of oil reservoirs refilling after being emptied is just one part of a large body of evidence for this process. Unfortunately this idea has met considerable problems because some people have hit upon this to try and say that oil is not running out and this blatant lie has given the whole idea of abiotic oil a bad name. Actually the refilling of oil fields is far to slow to be a significant factor in the world wide oil crisis. The Deep Hot Biosphere by Thomas Gold is a recent advocate of this process but the idea stretches back more than a hundred years and was the first explanation for the origin of oil. The Soviets also promoted this and of course western science rejected it out of hand due to this. See these links for more info.










sadly this idea is being hijacked by people who think it means oil is in unlimited supply and the people who say oil is limited are very reluctant to even consider the possibility of abiotic oil.
