Kerogen: from Types to Models of Chemical Structure

Abstract: Résumé -Les kérogènes : de la notion de types aux modèles de structure chimique -Le but de cet article est de présenter, à travers une revue des développements conceptuels et analytiques en géochimie dans la période , les principales étapes qui ont conduit, à travers la préparation et l'analyse des kérogènes d'une part, et l'étude de systèmes pétroliers de référence d'autre part, aux notions de types, chemins d'évolution et modèles statistiques de structure chimique des kérogènes. Le kérogène est défini comme … Show more

“…The reconstruction for a group of kerogen molecules should be based on the experimental results of their molecular weight, elemental composition and functional group spectrum. The kerogen molecule model used in the present work has been reported by Vandenbroucke [31] and Collell et al [7], which describes the coal-like kerogen sourced from liptinitic at the end of catagenesis. The element ratios are: H/C: $0.5, O/C: $0.02, S/C: $0.005, N/C: $0.005.…”

“…3). Indeed, some samples present very low HI values comparable to values obtained from coal (type III) samples, whereas the others correspond to type II organic-rich rocks, as expected for Lower Toarcian shales of the Paris Basin (Durand, 2003;Vandenbroucke, 2003). At the local scale, large differences in OM quality (i.e., TOC, HI and OI) can be observed along the core (Fig.…”

“…We deal with a simplified chemical kinetic in which a single type of kerogen generates one type of oil, yet this model can be extended to more complex kinetics. For a detailed description of the different types of kerogen and the kinetic cracking of kerogen into oil, see [26].…”
