The most important source of natural gas is natural gas. This is why it is called natural. It is not "made" from oil or coal. Natural gas forms by decomposition of organic material. Whether the organic material decomposes to coal, oil, or gas depends on the composition of the original material, time, pressure, and temperature. In theory, oil (=long chains ...

A significant part of the natural gas used around the world today comes from oil fields. On top of the oil is a layer of natural gas, and in the crude oil is dissolved natural gas. This will be released when the pressure drops during the extraction of the crude oil so the natural gas will be separated from the oil during the extraction process. Earlier ...

Most plastics are made from the already-sunk carbon of crude oil or natural gas, and as a result, can be at best carbon neutral. However, bioplastics such as cellulose acetate or polylactic acid are derived from plant sources; the carbon here comes from the atmosphere, and they can theoretically act as carbon sinks. However, even if we switched all our ...

The most important factor for petroleum becoming gas isn't a substance, it's temperature and pressure. Most reservoirs have varying degrees of both; the T&P dictates how much of each will form. Knowing the type of field tells you what you should expect, be it a natural reservoir (black gold), or peat bogs (oil sands). Geologists often refer to the ...
