... in petroleum formation, the thermal expansion of the organic liquids generated, and the increase in solubility of water in the bitumen network. A fundamental concept that emerges from hydrous pyrolysis experiments is that expulsion of oil from a source rock is a consequence of oil generation within a source...

... the rate of oil generation. According to DURAND s opinion high pressure shales may indeed exhibit higher temperatures, but for a different reason. According to DURAND fluids can move normally in shales exhibiting hydrostatic pres- sures and, therefore, heat can be carried away with the fluid...

... It has been recognised during the past decade that the principal phase of oil generation (Vassoyevich et al.') can be identified in deeply buried Sediments, notably through the study of the diagenetic evolution of hydrocarbons. This is achieved by investigating extracts from suites of fine...
