“…In 2020, rock type and hydraulic flow units were used as a successful tool for reservoir characterization of the Bentiu-Abu Gabra sequence, Muglad basin, SW Sudan (El Sawy et al, 2020;Shalaby, 2021;Shoghi et al, 2020;Wu et al, 2020). Machine learning is effectively used by Man et al (2021) to boost the prediction of permeability and reduces uncertainty in reservoir modeling. Recently, a variety of conventional methods and machine learning algorithms were investigated in determining hydraulic flow units (HFUs), and the performance of each method was evaluated (Fernandes et al, 2023a;Forbes Inskip et al, 2020;Kianoush et al, 2022bKianoush et al, , 2023cKianoush et al, 2023a;Masroor et al, 2023;mohammadinia et al, 2023;Shi et al, 2023;Yu et al, 2023).…”
