The development of on-line corrosion and bacteria monitoring techniques suitable for field use in pipelines has permitted direct field solutions of corrosion problems in pipelines without the need for back-up laboratory test programs. A pipeline with active bacterial corrosion was treated with biocide, which was found by on-line field monitoring to be highly effective in reducing corrosion rates in the pipeline system, and establishing the interval between treatments. Severe pitting was found on
coupons exposed in sediment in the monitor, and light pitting was found at the oil water interface. In contrast, no pitting was found on coupons exposed entirely to water.
