A sustainable approach to synthesize phosphonated chitosan using ball milling and its application for oilfield scale management
Mady, Mohamed F.; Haukereid, Eirik; Abdel-Azeim, Safwat; Hussein, Ibnelwaleed A.; Kelland, Malcolm A. ( Royal Society of Chemistry , 2022 , Article)For many years, the oil and gas industry has strived to develop environmentally friendly organophosphorus-based scale inhibitors. The natural polymer chitosan has recently gained significant importance for various upstream ... -
Flexible, Linear, and Systematically Expanded Tetraphosphonate Bolaamphiphiles and Their Inhibition Performance against Calcite and Barite Scale Formation
Mady, Mohamed F.; Abdelaal, Abdelrahman T.; Kelland, Malcolm A.; Liakaki-Stavropoulou, Stefania; Demadis, Konstantinos D. ( American Chemical Society , 2023 , Article)Oilfield scaling is one of the most prevalent water-based oilfield production problems. Chemical inhibitors are often used to combat and prevent scale deposition. The phosphonate functional group is commonly used in many ... -
Phosphonated Lower-Molecular-Weight Polyethyleneimines as Oilfield Scale Inhibitors: An Experimental and Theoretical Study
Mady, Mohamed F.; Karaly, Ali H.; Abdel-Azeim, Safwat; Hussein, Ibnelwaleed A.; Kelland, Malcolm A.; Younis, Ahmed... more authors ... less authors ( American Chemical Society , 2022 , Article)For many years, amino methylenephosphonate (-CH2-N-PO3H2)-based scale inhibitors (SIs) have been deployed for preventing various scales in the oil and gas industry, particularly for squeeze treatment applications. However, ... -
Phosphonated Polyetheramine-Coated Superparamagnetic Iron Oxide Nanoparticles for Inhibition of Oilfield Scale
Mady, Mohamed F.; Karaly, Ali H.; Kelland, Malcolm A. ( American Chemical Society , 2023 , Article)Oilfield scale is one of the significant problems in hydrocarbon production in the oil and gas industry. Many research groups have attempted to develop greener chemicals to meet environmental regulations. Magnetic nanoparticles ...
