DOI: 10.1016/j.marpetgeo.2020.104423
Abstract: Abstract Primary depositional variations interact with diagenetic modifications to exert strong control on pore networks in tight hydrocarbon reservoirs. However, the linkage between pore characteristics and depositional microfacies remains enigmatic, which restricts the prediction of… read more here.
