Kerosene, gas oil, paraffin (not the waxy solid of that name) is a colorless flammable hydrocarbon liquid. It is obtained from the fractional distillation of petroleum at 150 °C and 275 °C (carbon chains from the C12 to C15 range). At one time it was widely used in kerosene lamps but it is now mainly used as a fuel for jet engines (more technically Avtur, Jet-A, Jet-B, JP-4 or JP-8). A form of kerosene known as RP-1 is burned with liquid oxygen as rocket fuel. The name kerosene is derived from the Greek word keros (κερωσ, wax). Paraffin is a common name for a group of high molecular weight alkane hydrocarbons with the general formula CnH2n+2, where n is greater than about 20. ...

Typically, kerosene directly distilled from crude oil requires some treatment, either in a Merox unit or a hydrotreater, to reduce its sulfur content and its corrosiveness. Kerosene can also be produced by a hydrocracker, which is used to upgrade the parts of crude oil that would otherwise only be good for fuel oil.

Oil and Gas Extraction (3746 words)
Because oil and gas are difficult to locate, exploration and drilling are key activities in the oil and gas extraction industry.
When oil or gas is found, the drill pipe and bit are pulled from the well, and metal pipe (casing) is lowered into the hole and cemented in place.
Although worldwide demand for oil and gas is expected to grow, overall wage and salary employment in the oil and gas extraction industry is expected to decline by 28 percent through the year 2012, while employment in all industries combined is projected to increase by16 percent.
