DFT-MD dissolution of oilfield pyrite scale using borax
Onawole, Abdulmujeeb T.; Hussein, Ibnelwaleed A.; Ahmed, Musa E.M.; Saad, Mohammed A.; Aparicio, Santiago ( Qatar University Press , 2020 , Poster)Introduction: Oilfield scales including pyrite form in oil and gas pipelines, underground tubing, and surface equipment thus blocking the flow of fluids and hindering production. Hence, the need for the development of ... -
Effect of pH on acidic and basic chelating agents used in the removal of iron sulfide scales: A computational study
Onawole, Abdulmujeeb T.; Hussein, Ibnelwaleed A.; Saad, Mohammed A.; Mahmoud, Mohamed; Ahmed, Musa E.M.; Nimir, Hassan I.... more authors ... less authors ( Elsevier B.V. , 2019 , Article)Iron sulfide scale is a major challenge in the upstream section of the oil and gas industry. It is responsible for precipitate formation in tubulars, and it damages equipment. This leads to a loss in production. Mechanical ... -
Molecular and electronic structure elucidation of Fe2+/Fe3+ complexed chelators used in iron sulphide scale removal in oil and gas wells
Onawole, Abdulmujeeb T.; Hussein, Ibnelwaleed A.; Sultan, Abdullah; Abdel-Azeim, Safwat; Mahmoud, Mohamed; Saad, Mohammed A.... more authors ... less authors ( Wiley-Liss Inc. , 2019 , Article)Quantum chemical calculations based on DFT are employed to study the electronic structure and binding affinity of chelators used in the removal of iron sulphide scales. Three chelating agents, EDTA, HEDTA, and DTPA, are ... -
Theoretical Studies of a Silica Functionalized Acrylamide for Calcium Scale Inhibition
Onawole, Abdulmujeeb T.; Hussein, Ibnelwaleed A.; Saad, Mohammed A.; Ismail, Nadhem; Alshami, Ali; Nasser, Mustafa S.... more authors ... less authors ( MDPI , 2022 , Article)The calcium carbonate (CaCO3 ) scale is one of the most common oilfield scales and oil and gas production bane. CaCO3 scale can lead to a sudden halt in production or, worst-case scenario, accidents; therefore, CaCO3 scale ...
