Aggressive moves counter SRB in flooded subsea pipeline

摘要

Aggressive applications of biocide, use of hydrogen sulfide scavengers, and multiple pig runs can quickly eradicate even major infestations of sulfate-reducing bacteria in a repaired subsea natural gas pipeline following seawater incursion.Sample analysis made it possible to understand conditions within the pipeline and measure the treatment's effec-. tiveness, allowing Williams Midstream to regain control of internal corrosion mechanisms and quickly eradicate microbial populations, minimizing their threat to pipeline integrity.
