Abstract

The history of petroleum formation is summarized as a function of increasing burial of the source rock in Figure II.7.1, which represents the abundance and composition of the hydrocarbons generated, and in Figure II.7.2, which shows the correlative evolution of kerogens. The depth scale represented in Figure II.7.1 is based on examples of Mesozoic and Paleozoic source rocks. It is only approximate and may vary according to the nature of the original organic matter, its burial history and the geothermal gradient. Based on the fundamental knowledge presented in the previous chapters, the general scheme of oil and gas formation may be summarized as follows.
