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 ... -
Dissolution kinetics of different inorganic oilfield scales in green formulations
Ahmed M.; Hussein I.A.; Onawole A.T.; Saad M.A.; Mahmoud M. ( American Chemical Society , 2020 , Article)Scale mineral deposition is a critical problem that hinders the daily production of oil and gas fields. Chemical removal of these scales, based on the scale type, is common. In this paper, borax and diethylene tremaine ... -
Rheological characterization of NA2CO3 activated calcium bentonite for oil and gas drilling applications
Nasser, M.S.; Al-Marri, M.J.; Khraisheh, Majeda; Saad, M.A. ( AIChE , 2015 , Conference Paper)Calcium bentonite was activated with soda ash (Na2CO3) at various ratios and due to the ion exchange; the original Ca-bentonite was converted to Na-bentonite. It was found that the Na2CO3 activation improves the swelling ...
