Different types of kerogens convert to hydrocarbons at different rates, and they yield different quantities of various hydrocarbon phases. Therefore, one standard relationship between a measured maturity parameter and hydrocarbon generation does not exist. Values such as 0.6% vitrinite reflectance (Ro) are generally associated with the onset of oil generation or indicate the top of the oil window. However, this generality applies only if a source rock is composed of pure type II organic matter (marine kerogen).
