Alkharraa, H.S.H. (author)Oil exploitation of tight reservoirs has gained significant importance lately. Some researchers have defined tight reservoirs as those characterized with permeability lower than 0.1 mD. However, permeability is an absolute value, and tight reservoirs have complex pore systems that require a detailed geological and petrophysical rock...doctoral thesis 2024
