In response to rapid increases in pitting on coupons and plugging of injection wells in various locations of the Prudhoe Bay water floods, programs for monitoring of microbial contamination and corrosion in both the produced and sea waters has been developed. Since the original method was explained in 1985 at a previous NACE annual convention, a number of changes have been made to enhance the usefulness of the monitoring data. These changes include introducing various techniques to quantitatively evaluate the microbial populations and their viability. Side-stream devices have been installed to perform on-line monitoring of biocide performance and to conduct kill studies with various biocides. These techniques, the data collected and future plans to combat the problems will be discussed.
