they are organic compounds of carbon and hydrogen from the transformation of organic matter (plankton, plants, dead animals) following the increase in temperature and pressure under the effect of the process sedimentation-burying and are preserved in fine sediment to rock, usually of clay or marl, called source rocks.

Hydrocarbons (oil and natural gas) are of organic origin. A few, however, maintain that some natural gas could have formed deep within the earth, where heat melting the rocks may have generated it inorganically. 1)Nevertheless, the weight of evidence favors an organic origin, most petroleum coming from plants and perhaps also animals, which were buried and fossilized in sedimentary source rocks. 2)The petroleum was then chemically altered into crude oil and gas.

The chemistry of oil provides crucial clues as to its origin. Petroleum is a complex mixture of organic compounds. One such chemical in crude oils is called porphyri

animals and fossils and gas can be found with oil

Oil and Gas is non-renewable source of energy, they are formed by the burial of plants and animals after million of years it compact and bury deep by the time due to burial temperature and pressure increased which result in the formation of oil and gas (it include other chemical processes).
