Phage Shield is a unique product for combating biofilms and sulfate-reducing bacteria (SRB) involved in the biocorrosion process. The product has an unprecedented technology for the control of SRB and biofilms, free of chemical substances harmful to the environment, which consists of the use of bacteriophages isolated from the environment. Phage Shield has the potential to reduce the huge load of biocides that are currently used by oil and gas exploration companies. The product has high specificity for bacteria with great safety for aquatic fauna and humans.

Sulfate Reducing Bacteria (SRB) are the main microorganisms related to cases of biocorrosion of metals and biogenic acidulation (biological souring). This occurs due to the high production rate of H2S (sulfidric gas) as a product of the metabolism of this group of bacteria. As a direct consequence, we can mention the clogging of reservoirs; corrosion inside pipelines; high maintenance cost; reduction of the useful life of equipment; decreased oil recovery; reduction in the quality of the oil, in addition to possible risks and damage to workers’ health and the environment due to exposure to hydrogen sulfide. Based on this evidence, the importance of controlling these bacteria is clear and the justification for the annual use of tons of synthetic biocides that are dumped into the environment. Therefore, alternative products that can replace the biocides represents a great advance towards sustainability
