Biodegradable Preformed Particle Gel (PPG) Made of Natural Chitosan Material for Water Shut-Off Application
Elaf, Reem; Ben Ali, Ahmed; Saad, Mohammed; Hussein, Ibnelwaleed A.; Nimir, Hassan; Bai, Baojun... more authors ... less authors ( MDPI , 2023 , Article)Oil and gas extraction frequently produces substantial volumes of produced water, leading to several mechanical and environmental issues. Several methods have been applied over decades, including chemical processes such ... -
Chitosan/Polyacrylamide Green Gels for Water Control in High-Temperature Reservoirs
Shamlooh, Mohamed; Elaf, Reem; Hussein, Ibnelwaleed A.; Saad, Mohammed; Bai, Baojun ( American Chemical Society , 2022 , Article)The rheology of a gel system composed of polyacrylamide (PAM) and chitosan is studied under typical reservoir conditions. The impacts of the degree of chitosan deacetylation, temperature, and salinity on the gelation ... -

Elaf, Reem; Hamza, Ahmed; Nimir, Hassan; Saad, Mohammed; Hussein, Ibnelwaleed A.; Bai, Baojun... more authors ... less authors ( American Chemical Society (ACS) , 2024 , Article)Modern oil and gas extraction faces challenges, notably from the surplus of produced water, hampering hydrocarbon recovery and raising environmental and economic concerns. A promising solution is the injection of preformed ... -
Effect of pH on dissolution of iron sulfide scales using THPS
Ahmed, Musa; Onawole, Abdulmujeeb; Hussien, Ibnelwaleed; Saad, Mohammed; Mahmoud, Mohammed; Nimir, Hassan... more authors ... less authors ( Society of Petroleum Engineers (SPE) , 2019 , Conference Paper)Iron Sulfides scale has been a critical problem for oil and gas wells for several decades. One of the best candidates to remove these scales is tetrakis(hydroxymethyl)phosphonium sulfate (THPS). Most studies on the dissolution ... -
Geometrical and Electronic Analysis of Polyepoxysuccinic Acid (PESA) for Iron Sulfide Scale Inhibition in Oil Wells
Magadia, Patricia; Abdulla, Samah; Elbashier, Elkhansa; Hussein, Ibnelwaleed A.; Khaled, Mazen; Saad, Mohammed... more authors ... less authors ( MDPI , 2022 , Article)Scale formation causes major losses in oil wells, related to production and equipment damages. Thus, it is important to develop effective materials to prevent scale formation and inhibit any additional formation. One known ... -
