Applications/Directions for Use

Water Flood Injection Water

Glutaraldehyde 50% exhibits excellent stability in oilfield injection waters, which ensures that its antimicrobial activity will not be diminished in long pipelines. Hard waters or brines do not adversely affect its biocidal efficacy, and Glutaraldehyde 50% is non-ionic so it won’t interfere with the action of demulsifiers, corrosion inhibitors, orsurfactants Glutaraldehyde 50%water treatment microbiocides are typically slug dosed into the injection water on a daily or weekly basis at 50 to 2500 ppm active for up to 4 hours, although the exact treatment regimen will depend on the condition of the system, the amount of water being treated, etc.
Drilling, Completion, Workover, and Fracturing Fluids
Glutaraldehyde functions as a biocide over a broad pH range and its efficacy is much faster at neutral to alkaline pH’s than at acidic pH’s. Therefore, Glutaraldehyde 50% water treatment microbiocide products are excellent choices for use in preserving drilling muds and other oilfield fluids that are typically alkaline in pH. The combination of rapid alkaline efficacy at the typical use rates of 25 to 500 ppm as active, and proven stability and effectiveness in high salinity matrices ensures microbial protection of these important fluids.
Produced Waters
Most oilfield systems contain sulfate reducing bacteria (SRB’s) and acid producing bacteria (APB’s). The presence of SRB’s and APB’s presents a serious challenge for effective control of microbial contamination in a production system. For a biocide to be effective against these problematic organisms, it must be stable in the presence of sulfides or organic acids that are produced by these organisms. Glutaraldehyde 50%, unlike some other biocides (formaldehyde, acrolein, and isthiazoione) does not react with, and is not deactivated by, H 2 S or other organic acids. This ensures that all of the Glutaraldehyde 50% added is available to act as a biocide. Like its use in waterflood inection systems, Glutaraldehyde 50% is typically added in slug doses on a daily to weekly basis at concentration of 50 to 2500 ppm as active.

Oil and Gas Transmission lines
Biofilms are a major problems in oil and gas production systems and pipelines are often afflicted with biofilm-related problems. Microbiologically Influenced Corrosion (MIC) is often associated with the presence of a biofilm. The control of biofilms is therefore crucial to ensuring that corrosion events, due to microorganisms, are minimized.

Glutaraldehyde 50% has been shown to penetrate a biofilm and kill the microorganisms that are contained within it. The penetrating ability of Glutaraldehyde 50%, along with its long-term stability in oilfield waters, makes it an effective product to control established biofilms in pipelines and prevents the formation of new ones.
Gas Storage Wells and Hydrocarbon Storage Facilities
The water bottoms in hydrocarbon storage tanks and gas storage wells can often be contaminated with SRB’s and serve as hosts to biofilms. This, in turn, can lead to the formation of H2S in the gas storage facility and the corrosion of hydrocarbon storage tanks. Glutaraldehyde 50% preferentially partitions into the water phase in a mixed hydrocarbon/water system and so would attack any microorganisms that are present in these water bottoms.
Production Wells
The injection of scale and corrosion inhibitors into production wells can introduce microorganisms into the production equipment and the formation. The addition of Glutaraldehyde 50% during these injections (squeeze treatments) can help to control these microorganisms and may help reduce the occurrence of MIC in production equipment.
