Paper Number: AMPP-2023-19243
... (determined by considering sweet corrosion), very protective iron sulfide films may form, resulting in low corrosion rates even in the absence of CI (i.e., control tests), rendering chemical selection and qualification meaningless unless the inhibitor interferes with the protective film, resulting in enhanced...

... weight-loss coupons were used in the test. Some important standard tests (e.g., thermal stability) based on ASTM G170 were also presented. The test results showed that the HTHP corrosion inhibitor showed the target corrosion rate (less than 0.075 mm/yr) with no pitting corrosion. The thermal stability...
