Abstract
Geological reservoir models, created based on sparse core and seismic data, inform hydrocarbon production, geothermal applications and aquafer management. Important factors contributing to reservoir quality in these applications include the heterogeneities within and connectivity between the relevant geo‐bodies constituting the reservoir. The transport and preservation of sediment at the time of deposition impacts these factors. Therefore, a better understanding of sediment delivery, transport and deposition can be used to better quantify reservoir properties. This same computational methodology can also be applied test hypotheses concerning the depositional processes responsible for preservation of ancient deposits. Constraining such hypotheses improves our understanding of the paleo‐sediment dynamics and the accuracy of future geological models.
