Ab Initio molecular dynamics of the dissolution of oilfield pyrite scale using borax
Onawole A.T.; Hussein I.A.; Ahmed M.E.M.; Saad M.A.; Aparicio S. ( 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 ... -
Computational Screening of Potential Inhibitors of Desulfobacter postgatei for Pyrite Scale Prevention in Oil and Gas Wells
Onawole A.T.; Hussein I.A.; Saad M.A.; Ahmed M.E.M.; Nimir H. ( American Chemical Society , 2021 , Article)Sulfate-reducing bacteria (SRB), such as Desulfobacter postgatei are found in oil wells. However, they lead to the release of hydrogen sulfide. This in turn leads to the iron sulfide scale formation (pyrite). ATP sulfurylase ... -
Development of a New Borax-Based Formulation for the Removal of Pyrite Scales
Ahmed M.; Hussein I.A.; Onawole A.T.; Saad M.A. ( American Chemical Society , 2020 , Article)In the oil and gas industry, pyrite forms one of the most hardened scales in reservoirs, which hinders the flow of fluids. Consequently, this leads to blockage of the downhole tubular, formation damage, and complete shutdown ... -
Impact of aluminium acetate particles size on the gelation kinetics of polyacrylamide-based gels: Rheological and molecular simulation study
Hamza A.; Shamlooh M.; Hussein I.A.; Nasser M.S.; Onawole A.T.; Magzoub M.; Salehi S.... more authors ... less authors ( John Wiley and Sons Inc , 2021 , Article)Inorganically crosslinked polymers have been intensively implemented for conformance control treatments in oil and gas wells at low temperatures (<90°C) because of their faster gelation time compared to organically crosslinked ... -
Molecular Design of Novel Chemicals for Iron Sulfide Scale Removal
Onawole A.T.; Hussein I.A.; Nimir H.I.; Ahmed M.E.M.; Saad M.A. ( Hindawi Limited , 2021 , Article)Scale deposition is a pertinent challenge in the oil and gas industry. Scales formed from iron sulfide are one of the troublous scales, particularly pyrite. Moreover, the use of biodegradable environmentally friendly ...
