    • Capillary pressure correction of cuttings 

      Alessa, S.; Sakhaee-Pour, A.; Sadooni, F.N.; Al-Kuwari, H.A. ( Elsevier , 2022 , Article)
      The accurate characterization of capillary pressure is essential in determining multiphase flow behavior in subsurface conditions. It is also essential in quantifying reservoir rock quality, reservoir fluid saturations, ...

    • Characterizing fracture toughness using machine learning 

      Alipour, M.; Esatyana, E.; Sakhaee-Pour, A.; Sadooni, F. N.; Al-Kuwari, H. A. ( Elsevier B.V. , 2021 , Article)
      The existing models for fracture toughness characterization based on nanoindentations that account for the fracture length are limited to simple (ideal) geometries that are absent in shales. The present study proposes two ...

    • Comprehensive pore size characterization of Midra shale 

      Alessa, S.; Sakhaee-Pour, A.; Sadooni, F. N.; Al-Kuwari, H. A. ( Elsevier B.V. , 2021 , Article)
      Although the Middle East's carbonate reservoirs were the first and most studied rocks in the world, Middle Eastern shale reservoirs are still poorly understood compared with other unconventional formations in the US. We ...

    • Effect of strain on gas adsorption in tight gas carbonates: A DFT study 

      Elbashier E.; Hussein I.; Carchini G.; Sakhaee Pour A.; Berdiyorov G.R. ( Elsevier B.V. , 2021 , Article)
      The geometrical properties of the reservoir rocks are usually affected by natural thermodynamics or environmental changes. These factors may modify the distribution and the amount of gas in place in the reservoir. To address ...

    • Effect of surface morphology on methane interaction with calcite: a DFT study 

      Onawole A.T.; Hussein I.A.; Carchini G.; Sakhaee-Pour A.; Berdiyorov G.R. ( Royal Society of Chemistry , 2020 , Article)
      Natural gas, consisting primarily of methane, is found in carbonate reservoirs of which calcite is major component. However, the complexity and heterogeneity of carbonate reservoirs remain a major challenge in estimating ...

    • Empirical Relation for Capillary Pressure in Shale 

      Alipour, Mehdi K.; Kasha, Ahmed; Sakhaee-Pour, A.; Sadooni, Fadhil N.; Al-Kuwari, Hamad Al Saad ( Society of Petroleum Engineers (SPE) , 2022 , Article)
      Brooks and Corey (1964) and van Genuchten (1980) proposed the two most widely used relations for approximating capillary pressure. Petroleum engineers apply both, but they were originally proposed to understand the moisture ...

    • Machine Learning for Capillary Pressure Estimation 

      Kasha, A. A.; Sakhaee-Pour, A.; Hussein, I. A. ( Society of Petroleum Engineers (SPE) , 2022 , Article)
      Capillary pressure plays an essential role in controlling multiphase flow in porous media and is often difficult to be estimated at subsurface conditions. The Leverett capillary pressure function J provides a convenient ...

    • Microporosity evolution and destruction in the Jurassic Arab D reservoir, Qatar 

      Sadooni, F.N.; Al-Kuwari, H. Al Saad; Sakhaee-Pour, A.; Mattar, W. S. ( Institute for Ionics , 2023 , Article)
      Core samples were collected from three wells, one onshore and two offshore, from Qatar’s Upper Jurassic Arab D reservoir. The samples were subjected to multiproxy petrographic and chemical analyses to identify their micro- ...

    • Predicting carbonate formation permeability using machine learning 

      Tran H.; Kasha A.; Sakhaee-Pour A.; Hussein I. ( Elsevier B.V. , 2020 , Article)
      It is imperative to characterize the formation permeability to simulate the flow behavior at subsurface conditions. An accurate characterization at the core scale is possible when large samples are available, but often ...

    • The effect of vacancy defects on the adsorption of methane on calcite 104 surface 

      Berdiyorov G.R.; Elbashier E.; Carchini G.; Hussein I.A.; Sakhaee-Pour A. ( Elsevier Editora Ltda , 2021 , Article)
      Density functional theory calculations are used to study the effect of vacancy defects (ionic Ca and charge neutral CO3) on the adsorption properties of CH4 molecule on different calcite surfaces. Both types of vacancy ...
