The growing need for energy and the depletion of oil wells necessitate advanced Enhanced Oil Recovery (EOR) techniques, particularly water polymer flooding, which play a crucial role in augmenting hydrocarbon recovery rates. However, flooding high-permeability layers often leads to breakthroughs, reduced sweep efficiency, formation preferential channels, posing significant challenges reservoir management. Conformance control treatments, including use microspheres, offer promising solution by...
Abstract Three compounds namely; 5‐(phenyl)‐4 H ‐1,2,4‐triazole‐3‐thiol, 3‐(decylthio)‐5‐phenyl‐1 ‐1,2,4‐triazole and 3‐(benzylthio)‐5‐phenyl‐1 ‐1,2,4‐triazole) were synthesized. The chemical structure of the prepared was confirmed using FTIR 1 H‐NMR analysis. tested as corrosion inhibitors against carbon steel in M HCl weight loss, polarization electrochemical impedance methods. results revealed that these have significant inhibiting effects on steel. Polarization studies showed act...
Abstract It is well known that tetra hydroxymethyl phosphonium sulfate (THPS) commonly used in oil fields as a biocide for sulfate‐reducing bacteria (SRB), but it has low corrosion inhibition. In this study, four surfactant compounds were synthesized via coupling reaction between THPS and different fatty acids namely: decanoic, dodecanoic, palmitic stearic to produce the corresponding surfactants. The chemical structure of surfactants was confirmed using FTIR 1 H‐NMR spectroscopy. surface...
Three Gemini quaternary ammonium surfactants based on polyethylene glycol have been prepared and characterized using FTIR 1HNMR spectra. The effect of ethylene oxide units' number the steel corrosion in 1.0 M HCl has estimated weight loss, polarization electrochemical impedance spectroscopy. Gravimetric technique done at three different temperatures 25, 40 55 °C. synthesized cationic with higher molecular (higher units) showed inhibition efficiency under all conditions. All inhibitors upon...
In this work, poly 12-(3-amino phenoxy) dodecane-1-thiol surfactant self assembled on silver nanoparticles was synthesized and characterized by different techniques. The polymeric its nanostructure with the prepared were examined as non-toxic corrosion inhibitors for carbon steel in 1 M HCl solution using weight loss potentiodynamic polarization results show that value of percentage inhibition efficiency (IE%) obtained is better than only. Polarization data indicate selected additives act...
