Combining biodegradation in 2D petroleum system models: application to the Cretaceous petroleum system of the southern Persian Gulf basin

Biodegradation modeling is combined with petroleum system modeling along a regional 2D transect from the southern Persian Gulf basin. An advanced basement model was considered in the model that allowed a constant temperature to enter the entire sedimentary column. Modeling results were calibrated ag...

Description
Summary:Biodegradation modeling is combined with petroleum system modeling along a regional 2D transect from the southern Persian Gulf basin. An advanced basement model was considered in the model that allowed a constant temperature to enter the entire sedimentary column. Modeling results were calibrated against existing temperature and vitrinite reflectance data from nearby wells. Temperature, burial, and charge histories are carefully monitored within the studied section through geological time. Based on our modeling results, biodegradation has been effective along the migration pathway and within the eventual accumulation sites to varying extents. These findings can have practical implications for pre-drill oil quality predictions and accurate geochemical evaluations of oils and reduce offshore oil and gas exploration risks.
