Microbiologically influenced corrosion and souring ofoilfield reservoirs are process frequently provoked by the sulphate-reducingbacteria. The most common method applied in the industry for preventing orcontrolling the deleterious effect caused by the presence of microorganisms isthe addition of chemical agents (biocides) aimed at killing the microorganismsor inhibiting the microbial growth. Traditionally, biocide selection andtesting are based on NACE standard TM0194 which implies the use of culturingfor enumerating the bacteria surviving the treatment.
