A theoretical study of gas adsorption on calcite for CO2 enhanced natural gas recovery
( European Association of Geoscientists and Engineers, EAGE , 2019 , Conference Paper)The adsorption of gas molecules (CO2, CH4, H2O, H2S and N2) on calcite (104) has been studied by means of Density Functional Theory, in order to investigate the molecular characterization of Enhanced Gas Recovery (EGR) ... -
Applications of chelating agents in the upstream oil and gas industry: A review
( American Chemical Society , 2020 , Article Review)Chelating agents show very effective performance in different applications in the upstream oil and gas industry. This study presents a critical review of the application of chelating agents in acidizing, scale removal, ... -
Characterization of H2S gas sensor based on CuFe2O4nanoparticles
( Elsevier Ltd , 2017 , Article)Copper ferrite (CuFe2O4) nanoparticles were prepared by the sol-gel auto-combustion method and used to construct a conductometric gas sensor in this work. The as-prepared CuFe2O4 nanoparticles were annealed at 500 °C and ... -
Corrosion behavior of API X-80 steel in hydrogen sulfide environment at different temperatures
( National Assoc. of Corrosion Engineers International , 2016 , Conference Paper)The electrochemical behavior of API X-80 steel materials in 3.5% wt. of NaCI solution containing different concentration of H2S at different temperatures was studied. Potendiodynamic polarization, electrochemical impedance ... -
Pyrite-scale removal using glutamic diacetic acid: A theoretical and experimental investigation
( Society of Petroleum Engineers (SPE) , 2021 , Article)Iron sulfide scale causes major losses in both upstream and downstream sectors of the hydrocarbon industry. Pyrite is one of the most-difficult forms of iron sulfide scale from a removal point of view. Inorganic acids such ... -
Review of Iron Sulfide Scale Removal and Inhibition in Oil and Gas Wells: Current Status and Perspectives
( American Chemical Society , 2021 , Article Review)Iron sulfide scale is one of the main types of inorganic scales that block oil and gas wells. Iron sulfide has polymorph crystallinity structures, which complicate its dissolving and inhibition. Hydrochloric acid (HCl) is ...
