Achieve Long-term Control with Non-ionic, Balanced 2K7 Biocide

Water provides an ideal environment for the proliferation of microorganisms and, if uncontrolled, can cause significant problems including increased operating costs. In the energy industry, the development and operation of an oilfield goes through several distinct phases, all of which can be affected by unwanted microbial growth. Microbial contamination can occur during drilling of the well, hydraulic fracturing, coiled tubing millouts, waterflood, construction of the facilities and production itself.

Many operations in the oilfield industry tend to present anaerobic environments, favouring the proliferation of sulfate reducing bacteria (SRB), resulting in the production of H2S. 2K7 biocide helps control microbial growth, preventing significant problems including reservoir souring, metal corrosion, biofilm buildup and health hazards.

Wherever there is water there are microbes. Depending on the application, microbial contamination can lead to serious issues such as fouling, souring and corrosion.

How 2K7 Biocide Works

2K7 biocide disrupts microbial activity by incorporating into sulfur-containing proteins. The antimicrobial activity is not associated with bromine or formaldehyde. 2K7 is non-ionic and very compatible with most chemicals including other biocides however it will interact with thiol groups, and dosages may need to be adjusted appropriately to overcome said reactions. Oxygen scavengers like sodium bisulfite may be used to deactivate 2K7. Always check effectiveness and compatibility before applying this product into fluid systems or alongside other chemical treatments.

OSP 2K7 biocide provides consistent microbial control and outlasts current product in Texas coiled tubing operation


Coiled tubing (CT) mill out of bridge plugs is a common operation. To increase the lifespan of their tubing, Service Companies are turning to a variety of products to mitigate microbiologically influenced corrosion (MIC), which has been shown to cause pitting leading to premature string failure. Microbial growth in mill-out fluids pumped downhole can also cause formation damage, such as souring.

Frequently Asked Questions

Does it matter which biocide I choose for my upcoming frac?

Within the frac process it is important to select the right biocide for the job and to test the effectiveness for the duration of the frac job. While all biocides provide a method of kill, some offer a quick kill, immediately knocking down the microbial load, while others are work horses, offering long term reliability. It is important to think about the following: How long does water sit on location before pumping? How long is the pumping time? How long is the shut-in period? Complete a kill study at least to the point of flowback time to ensure the kill takes into consideration source water, microbial load, length of time and overall desired kill.

What are the long-term production benefits of treating with 2K7 biocide?

The usage of 2K7 biocide prevents bacterial contamination and growth, controlling issues that arise from their presence, including microbiologically influenced corrosion (MIC). 2K7 reduces the risk of failures, improves run time on pipe, prevents contamination of downhole equipment and controls formation damage.

Is 2K7 compatible with most chemistries?

Yes. 2K7 is non-ionic and therefore very compatible with most system components within the oil and gas industry.

Can microbes develop a resistance to 2K7 over time?

Very unlikely. While it has been proposed that microbes can develop resistances to organic biocides, this has not been seen with 2K7 applications nor is it likely based on application methods used within our industry.
