Abstract
Anaerobic microbiological activities of two oil-producing facilities were determined by monitoring
microbial activities in CSB-K medium and MPN counts of SRB in API RP-38 broth medium and APB
in ZPRA-5 broth medium. Corrosion measurements were also carried out by weight loss method. Our
investigation revealed that microbial activities at the near-shore facility were dominated by both sulfate
reduction and methanogenesis with potential for souring and corrosion, while that of offshore was
dominated by sulfate reduction, but the potential for souring and corrosion were reduced by frequent
application of a combination of biocides by the operators.
