Ab Initio molecular dynamics of the dissolution of oilfield pyrite scale using borax
( Elsevier B.V. , 2020 , Article)Iron sulfide scales, particularly pyrite, form in oil and gas underground tubing and surface equipment thus blocking the flow of fluids and halting production. Therefore, the development of physicochemical processes for ... -
Application of DFT in iron sulfide scale removal from oil and gas wells
( European Association of Geoscientists and Engineers, EAGE , 2019 , Conference Paper)Scale formation including those formed by iron sulfides have been a major hassle in the upstream sector of the oil and gas industry for many decades. Iron Sulfide scales including pyrite (FeS2) and troilite (FeS) often ... -
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, ... -
Current advances in bio-fabricated quantum dots emphasising the study of mechanisms to diversify their catalytic and biomedical applications
( Royal Society of Chemistry , 2021 , Article Review)Quantum dots (QDs), owing to their single atom-like electronic structure due to quantum confinement, are often referred to as artificial atoms. This unique physical property results in the diverse functions exhibited by ... -
Microalgae potential to protect from heavy metals-induced carcinogenicity
( Elsevier , 2024 , Article)Toxic elements are present naturally in the environment; however, during the last century, their level has been continuously rising in the air, water, and soil due to anthropogenic activities, including urban runoff, ... -
Mussel-mimicking sulfobetaine-based copolymer with metal tunable gelation, self-healing and antibacterial capability
( Elsevier B.V. , 2020 , Article)In the present study, the sulfobetaine-based copolymer bearing a dopamine functionality showed gel formation adjusted by the application of metal salts for gelation and various values of pH. Normally, the liquid-like ... -
Rheology of Triamine Functionalized Silica Reinforced Polymeric Gels Developed for Conformance Control Applications
( American Chemical Society , 2020 , Article)Recently, cross-linked polymers such as polyacrylamide (PAM)/polyethylenimine (PEI) have been used in conformance control applications to replace conventional lost circulation materials (LCMs). The objective of this work ... -
Synthesis and evaluation of a novel polyacrylamide functionalized nano-silica as a calcium carbonate inhibitor in upstream applications
( Elsevier B.V. , 2022 , Article)Calcium carbonate scale forms in production and injection wells, precipitating upon pressure and temperature changes, incompatible water mixing, and dehydration. Production shutdown is one of the most dramatic consequences ...
