An Investigation of the Swelling Kinetics of Bentonite Systems Using Particle Size Analysis
( Taylor and Francis Inc. , 2019 , Article)Particles size distribution (PSD) is introduced as a tool for analysis of bentonite aggregation and swelling kinetics. Raw Ca-bentonite was purified using a combined wet sieving and sedimentation processes, followed by ... -
Effect of pH on acidic and basic chelating agents used in the removal of iron sulfide scales: A computational study
( Elsevier B.V. , 2019 , Article)Iron sulfide scale is a major challenge in the upstream section of the oil and gas industry. It is responsible for precipitate formation in tubulars, and it damages equipment. This leads to a loss in production. Mechanical ... -
Hydrogen storage in gas reservoirs: A molecular modeling and experimental investigation
( Elsevier , 2023 , Article)Hydrogen is one of the clean energy sources that can be used instead of fossil fuel sources to reduce greenhouse emissions. However, hydrogen supply intermittency significantly reduces the deployment and reliability of ... -
Introduction to reservoir fluids and rock properties
( Elsevier , 2023 , Book chapter)Hydrocarbon reservoirs contain gas, oil, water, and brine within the pores. The interactions between these fluids and the reservoir rocks have a considerable role in distributing the phases in the porous media. Understanding ... -
Iron Sulfide Scale Inhibition in Carbonate Reservoirs
( American Chemical Society , 2022 , Article)Hydrocarbon production operations include water injection, varying stimulation approaches, and enhanced oil recovery techniques. These treatments often affect reservoir formation, production, and injection facilities. Such ... -
Molecular and electronic structure elucidation of Fe2+/Fe3+ complexed chelators used in iron sulphide scale removal in oil and gas wells
( Wiley-Liss Inc. , 2019 , Article)Quantum chemical calculations based on DFT are employed to study the electronic structure and binding affinity of chelators used in the removal of iron sulphide scales. Three chelating agents, EDTA, HEDTA, and DTPA, are ... -
Molecular dynamics of CH4/CO2 on calcite for enhancing gas recovery
( John Wiley and Sons Inc , 2022 , Article)The effect of temperature and pressure on the adsorption of CO2 and CH4 gases on calcite (104) has been studied by means of classical molecular dynamics. The results show that carbon dioxide greatly improves methane ... -
Upgrading Calcium Bentonite to Sodium Bentonite Using Seawater and Soda Ash
( American Chemical Society , 2019 , Article)In this paper, a new method is introduced to produce sodium bentonite by treating calcium bentonite using seawater to eliminate the use of freshwater and reduces the amount of soda ash required for the treatment, which ...
