Antiscaling Evaluation and Quantum Chemical Studies of Nitrogen-Free Organophosphorus Compounds for Oilfield Scale Management
Mady, Mohamed Fawzy Hamed Attia; Abdel-Azeim, Safwat; Kelland, Malcolm A. (Peer reviewed; Journal article, 2021-08)Nonpolymeric aminomethylenephosphonates are widely used as powerful scale inhibitors in the petroleum industry. However, most of these inhibitors have certain drawbacks, such as low biodegradability and incompatibilities ... -
Investigation of the Antiscaling Performance of Phosphonated Chitosan for Upstream Petroleum Industry Application
Mady, Mohamed Fawzy Hamed Attia; Abdel-Azeim, Safwat; Kelland, Malcolm Andrew (Peer reviewed; Journal article, 2021)Scale deposition is one of the main water-based production problems in the upstream oil and gas industry. Few environmentally friendly scale inhibitors show good thermal stability as well as calcium compatibility. We report ... -
N‑Vinyl Caprolactam/Maleic-Based Copolymers as Kinetic Hydrate Inhibitors: The Effect of Internal Hydrogen Bonding
Kelland, Malcolm Andrew; Pomicpic, Janronel Calog; Ghosh, Radhakanta; Abdel-Azeim, Safwat (Peer reviewed; Journal article, 2022)Kinetic hydrate inhibitors (KHIs) have been used for over 25 years to prevent gas hydrate formation in oil and gas production flow lines, but they are some of the most expensive oilfield production chemicals. The main ... -
Phosphonated Lower-Molecular-Weight Polyethyleneimines as Oilfield Scale Inhibitors: An Experimental and Theoretical Study
Mady, Mohamed Fawzy Hamed Attia; Karaly, Ali H.; Abdel-Azeim, Safwat; Hussein, Ibnelwaleed A.; Kelland, Malcolm Andrew; Younis, Ahmed (Peer reviewed; Journal article, 2022)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, ...
