Effect of Trace 100 vppm H2S on the Corrosion Behaviour of Plain Carbon and Microalloyed Steels in a Predominant Sweet Environment in High Flow Regime
Sk, Mobbassar hassan; Abdullah, Aboubakr Moustafa; Al-Qahtani, Noora Hamad S; Laycock, Nick; Ryan, Mary P; Williams, David E... more authors ... less authors ( Hamad bin Khalifa University Press (HBKU Press) , 2018 , Conference Paper)We investigate the effects of the presence of trace (100 vppm) H2S on the corrosion behaviour of plain carbon steel and its various micro-alloyed counterparts in a CO2 saturated (sweet) brine (0.5 M NaCl) environment, in ... -
Formation and Structure of Sulfide Deposits on Carbon Steel Under Free Corrosion Potential
Al-Qahtani, Noora; Qi, Jiahui; Abdullah, Aboubakr M.; Laycock, Nicholas J.; Ryan, Mary P. ( Association for Materials Protection and Performance , 2021 , Article)The corrosion of alloy materials in the H2S environment has considerably limited the growth of oilfield manufacturing. The sour corrosion of iron has frequently been studied, and steel corrosion under the H2S scheme has ... -
Nanoscale studies of the early stages of scale formation in sour environments
Al-Qahtani, Noora; Qi, Jiahui; Abdullah, Aboubakr M.; Laycock, Nicholas J.; Ryan, Mary P. ( one petro , 2018 , Article)The corrosion of carbon steel in environments containing hydrogen sulfide (H2S) is a critical issue to the oil and gas industry. Although considerable research efforts have been carried out, there is not yet a complete ... -
The Formation of Sulfide Scales on Carbon Steel in Saturated H2S
Alqahtani, Noora; Qi, Jiahui; Abdullah, Aboubakr M.; Laycock, Nicholas J.; Ryan, Mary P. ( Qatar University Press , 2020 , Poster)"There are three contributing elements of corrosion of Carbon Steel in H?S environment: the effect of H2S on water chemistry; electrochemical reactions of the bare iron surface (both anodic and cathodic processes); and the ...
