Bactericides - (Biocides)

Oilfield producing systems may experience problems with corrosion or hydrogen sulfide gas (H2S) attributed to bacteria. The bacteria causing the problem may be acid producing bacteria (APB) or sulfate reducing bacteria (SRB).

These organisms can attach to surfaces, forming a biofilm. The activities of the attached or “sessile” bacteria living in the biofilm can lead to the following problems in the oilfield.

• Corrosion of metal surfaces
• The generation of hydrogen sulfide (H2S) and iron sulfide
• Plugging of production and injection wells
• Plugging of water filtration systems
• Fouling of production processing equipment and storage vessels

Biocides are used to control bacteria populations. There are four (4) types of biocides including quaternary amine salt, amine acetate, aldehydes, and organic sulfur compounds. Bactericides can be injected continuously or via batch (slug) methods.
