Bacterial activity can have a profound bearing on the operation and integrity of a water injection system. The presence of harmful bacteria in such systems can lead to corrosion of equipment, group lines, and injection wells, as well as formation plugging, and as a result, decreased water injectivity. Formation plugging can occur due to bacterial biomass and the generation of corrosion products such as iron sulfide. A strategy for the control of microbiologically influenced corrosion was designed, which includes definition of the baseline, identification of critical areas and associated controls, monitoring and assurance activities. This strategy allowed reducing the concentration of bacteria to target values (less than 100 Bact/mL) and reducing failures due to corrosion.
