The process of formation of petroleum

Sakjane been a while I wanted to create a fairy tale or oil formation process occurs in the earth. But since no urgency ya guns only now finally this mythical writing. If yes buanyak scientific paper. Cuman often use jargon and terms that are only known at the gods up there


Theory of Organic and Inorganic theory

The theory of oil formation process known until now there are two major theories, namely the theory of inorganic and organic theory. Inorganic theory is now rarely used in oil and gas exploration. One of the developers of an organic theory are the followers of creationist - or adherents of the principle of creation. An-organic theory is also often known abiotic or abiogenic.

Fairytale time only for organic theory only.

Perhaps no one thought earlier that natural oil that is naturally created by these natural base ingredients from algae. Yes, in addition to algae, other biota in the form of leaves can also be a source of petroleum. But marine algae is important in producing oil. However, in the study of petroleum known that plants are high levels will produce more gas than oil produced. This is because the carbon chain is also more complex.

 

After the algae dies, it will be on the basis of sedimentary basins teredapkan. The presence of these algae can also at sea or in a lake. So it could be algae freshwater algae, and sea algae. Course the carbon-containing rocks can rock the result of deposition on the lake, in the delta, as well as on the sea floor. Rocks that contain a lot of carbon is called the Source Rock (rock Parent) contains elements Carbon-rich (high TOC-Total Organic Carbon).The process of formation of carbon from the algae to the host rock is very specific. That is why not all sedimentary basins will contain oil or gasbumi. If carbon is oxidized it will decompose and even a carbon chain that can not be cooked.

    Oil-3.jpgRock deposition process goes on and on. If this area continues to sink and continued by rocks piled on top of another, the rocks containing carbon will be heated. Course the we know that the entry into or vanish into the earth, the temperature will increase. Remember there is a geothermal gradient? (See explanation below maturation).Reservoir (rock Nest)
For a little more sophisticated in understanding the formation of oil and gas, the following tale explains just a matter of maturation.

As mentioned above that the maturation of source rock (host rock) is due to the heating process. Also known more in the host rock will ultimately generate more heat and oil. Surely there donk relationship between the depth of the maturation? Oh course the.

The cooking process is temperature dependent, and because the temperature depends on the size of the geothermal gradient, each area is not the same level of maturity.

Cold regions is low geothermal gradient areas, while areas of high geothermal gradient heat has.


In this picture it appears that oil is formed at temperatures between 50-180 degrees Celsius. But the peak or part of maturity is achieved when the temperature reaches 100 degrees Celsius. As the temperature continues to increase as it gets down in the basin that also followed the addition of rock hoarders, the high temperature will cook the existing carbon into gas!

Below is a map showing the notches of the oil producers in Indonesia. The green color indicates that the basin has produced oil and gas is greater than 5 Boe (Billion Oil Equivalent) or over 5 billion barrels of oil. Then between 1-5 billion, producing the yellow 1-1000 million barrels, and less than 10 million barrels of oil.

Basin-sedimentary basins in Indonesia was depicted in the picture on the top is not the same as each other, it shows there are still many that have not been discovered. Still need the technology, energy and thoughts and skills to seek and find.
