- W4285188564 abstract "Summary Earth Systems paleoclimate predictions can be used to address hydrocarbon exploration questions and reduce risk. We have developed a first-pass screening workflow that integrates data, geological principles and ‘ground-truthed’ paleoclimate models that allow us to predict the likely distribution and driving mechanism for source rocks in deep geological time. We demonstrate how this workflow can be applied to the East African margin. Despite numerous gas discoveries, the East African margin remains a frontier region for oil exploration as there have been very few substantial oil discoveries. Our geodynamic reconstructions show that the southern half of this margin formed the northern margin of the paleo-Southern (Austral) Ocean. This ocean would have been highly restricted, stratified, and anoxic in the Early Cretaceous — conditions strongly favoring the preservation of organic matter. Our climate predictions indicate that organic matter productivity in this ocean was caused by seasonal upwelling supplemented by localised inputs of terrestrial organic nutrients from rivers. We predict the most likely locations for Early Cretaceous, oil-prone, oil-mature source rocks on the East African margin together with a proxy for thickness: these results correspond to recent exploration successes in South Africa." @default.
