In this paper the compatibility of the biocide tetrakis(hydroxymethyl) phosphonium sulfate (THPS) and the oxygen scavenger ammonium bisulfite (ABS) were explored. Performance testing of both the biocide in the presence of the oxygen scavenger and the oxygen scavenger in the presence of biocide are reported.
The new passivation mechanism in steam-assisted gravity drainage (SAGD) process is discussed through theoretical approach in this paper. A corrosion mitigation program was implemented that included the pigging both slug and batch corrosion inhibitors chemistry analysis corrosion rate (CR) monitoring and non-destructive tests.
Biocorrosion or microbiologically influenced corrosion (MIC) is a major problem in the oil and gas industry. Biofilms are the culprits of MIC. In this work, D-amino acids were used to enhance two biocides, alkyldimethylbenzylammonium chloride (ADBAC) and tributyl tetradecyl phosphonium chloride (TTPC), to treat a field biofilm consortium on C1018 carbon steel coupons.
