Generation of hydrocarbons from organic matter

The three main stages of evolution of organic matter in sediments upon burial are diagenesis, catagenesis and metagenesis. The evolutionary stages 

Sediments deposited in a sedimentary basin in subaquatic environments, contain large amounts of water, minerals, dead organic matter and numerous 

This type is usually related to marine organic matter deposited in a reducing environment with medium to high sulfrir content. The hydrogen to carbon ratio and the oil and gas potential are lower than observed for type I kerogen but still very important.

Residual kerogen is one form of dead carbon and has no potential for oil and gas. Besides kerogen, at the end of diagenesis organic matter comprises a minor amount of free hydrocarbons and related compounds, as synthesized by
