Application of mathematical and machine learning models to predict differential pressure of autonomous downhole inflow control devices
(Peer reviewed; Journal article, 2021)Controlling reservoir fluid flow is important for maximizing petroleum production through wellbores. A major challenge that reduces the production of oil is early breakthrough of secondary fluids to the wellbore perforations. ... -
Characterization and capillary pressure curve estimation of clayey-silt sediment in gas hydrate reservoirs of the South China Sea
(Peer reviewed; Journal article, 2023)The capillary pressure curve is a crucial basis for studying the pore structure and multiphase flow characteristics in oil and gas reservoirs. Due to the loose and unconsolidated nature of the clayey-silt sediment of natural ... -
The Influence of Adsorption Layer Thickness and Pore Geometry on Gas Production from Tight Compressible Shales
(Peer reviewed; Journal article, 2021-12)In tight shales, gas is stored in both free and adsorbed form. A one-dimensional model is derived for shale gas production by pressure depletion where the adsorbed layer thickness is of similar magnitude as the pore radius ... -
Insights from Boltzmann transformation in solving 1D counter-current spontaneous imbibition at early and late time
(Peer reviewed; Journal article, 2023)Counter-current 1D spontaneous imbibition in scaled form is investigated using Boltzmann transform before and after water meets the closed boundary (early and late time). At early time the system is self-similar and only ...
