No it starts with finding it first. That's the hard part.

Hydrocarbons produce energy when they are burned, producing water and carbon dioxide and carbon monoxide. This releases the stored energy, and leaves the byproducts in a lower energy state.

Paraffin is actually the final product to come from petroleum after a distillation process involving steam that separates the different components, or chains of hydrocarbons from the raw petroleum.  This is a process of distillation, separating, filtering and cleaning.

Here are the official statistics from the Department of Energy. It includes the percentages from various international sources. I doubt the CIA has this. \n\nhttp://www.eia.doe.gov/oil_gas/petroleum/info_glance/petroleum.html\n\nIf you seek more detailed information try this site at BP.

ORIGIN AND FORMATION:\n\n Crude oil is formed from accumulations of small organisms, mostly phytoplankton and zooplanton that are buried in sediments in both marine and lacustrine (fresh water) environments. Other organic material is mixed in such as spores, pollen, woody material, and other material such as fecal pellets from marine organisms. These materials often settle through the water into an organic-rich mud that is very low in oxygen (anaerobic) so there are few organisms to feed on the material and it accumulates over long periods of time. Rivers contribute to this process by both delivering large quantities of organic matter, and also large amounts of sediment to bury this organic matter.\n\nOver time these clay-rich sediments are buried under thousands of feet of sediments, dewatered by pressure from the overlying sediment and become shale. As the shale is buried its temperature increases due to geothermal warming. When it reaches temperatures and pressures of 140 degrees F. (60 C) it begins to convert to oil. As temperature increases from continuing burial processes it reachs a temperature where it begins to form natural gas. Both the oil and the gas are gradually expelled from the shale. Typically shales are found in depositional settings where they may be interbedded with sandstones. Sandstones will have higher porosity (more and bigger holes) than shale and the oil and gas will displace salt water that is remaining in the sandstones. Eventually the oil and gas migrates upward through the water and if the overlying structure has formed some sort of a trapping configuration, (like a sandstone overlain by an impervious shale, or a fault that has created a seal against the sandstone, then this becomes an oil reservoir.\n\nA very similar process occurs in carbonate rocks, like limestone and dolomite, except the organic material originates within the carbonate rock in many instances. If the carbonate reef (for example) has been buried by an impervious layer of shale or carbonate mud of a sabkha, it will become an oil reservoir. In other instances, the source of the oil will be a shale that is below the carbonate rocks, and the oil will migrate upward into this reservoir.\n\n\nReference: John M Hunt, 1996, "Petroleum Geochemistry and Geology", W.H. Freeman & Co: New York. 743 pp. \n\n                                  COMPOSITION:\nCrude oil is a complex mixture of many different hydrocarbon compounds and also may contain sulphur and trace amounts of heavy metals. Because of this, different reservoirs of oil can be distinguished and identified using gas chromatography and other methods. It is even possible to identify particles of the original organisms and plant remains under a microscope in some crude oil. The list of hydrocarbon compounds found in crude oil numbers in the hundreds, but here is a list of the most common:\nParaffins:\n  Pentane\n  Hexane\n  Octane\n  Nonane\n  Decane\n\nBranched chain paraffins:\n  2-Methylpentane\n  3- Methylpentane\n  2-Methylhexane\n  3-Methylhexane\n  2-Methylheptane\n  Pristane\n \nCycloparaffins:\n  Methlycyclopentane\n  Cyclohexane\n  Methylcyclohexane\n  1,2-Dimethylcyclopentane\n  1,3- Dimethylcyclopentane\n  1,3-dimethylcyclohexane\n\nAromatics:\n  Benzene\n  Toluene\n  Ethylbenzene\n  m-Xylene\n\nOr described by molecular size, using a common crude oil for an example:\n  Gasoline (C5-C10)  27%\n  Kerosine (C11-C13) 13%\n  Diesel fuel (C14-C18) 12%\n  Heavy gas oil (C19-C25)10%\n  Lubricating oil (C26-C40)20%\n  Residuum(>C40)                   18% \n\nThere is an interesting thing about biomarkers in oil. There are petroleum reservoirs offshore West Africa, and offshore Brazil, that came from the same source of oil, showing that the oil formed before Africa and South America were separated by the Atlantic Ocean.

Organic matter does not have to be heated to form petroleum.  Petroleum forms from compression AND heat.

First, there are several "grades" of crude oil.  Heavier oil products less gasoline and lighter crudes produce more.  The average is around 19 1/2 gallons of gasoline per barrel of crude.\n\n"The 42-gallon barrel of crude oil makes about 19½ gallons of gasoline, 9 gallons of fuel oil, 4 gallons of jet fuel, and 11 gallons of other products, including lubricants, kerosene, asphalt, and petrochemical feedstocks to make plastics. [See also this EIA page] That adds up to more than 42 gallons because of something called "refinery gain" - the processing and chemical changes increase the density and hence the volume of the refined components. So, crudely (pun intended), a $37 barrel of crude represents about 88 cents a gallon to start with. That 88c represents the cost of production plus producer profit. Go up from there."

Distillation is a process by which a mixture of compounds is separated based on boiling point differences.  Crude oil is a mixture of many different organic molecules, which come in a wide range of molecular weights, which, in turn, leads to differences in boiling point.  So refineries take advantage of this by using many distillation processes in series.  One column operating at a relatively low temperature might separate waxes from more volatile compounds.  Another column, operating at a higher temperature, would separate light alkanes like propane and butane from heavier ones like hexane, heptane and octane.  Each of these streams might then go on to another distillation column or to some other method of separation.\n\nOn any given column, the distillate is the ligher, vapor stream exiting at the top of the column.  The liquid stream exiting at the bottom is called the bottoms.
