Protect and Control Microbial Growth

2K7 Solution

2K7 Solution is a responsive, long term control biocide; the main mode of action
is inhibition of thiol-containing enzymes causing cell leakage and eventual collapse.
2K7 has a high level of activity against all groups of bacteria including sulfate
reducing bacteria (SRB). The efficacy of 2K7 is easily measured using ATP testing
methods. Resistance or high level tolerance has not been observed with 2K7 even
in facilities that have used the product for over 15 years.

Properties

Appearance: Clear to yellowish, solution
pH: 4-7 1% sol. @ 20°C / 68°F
Solubility in Water: Completely miscible in water
Odor: Odorless
Decomposition Temp: 140°C / 284°F
Packaging: Pails, drums and totes

*2K7 Solution is not winterized, making it more cost effective for applications where freezing is not an issue. For a winterized solution, 2K7 Solution W-M is available with a freeze point of -40°C / -40°F.

2K7 BIOCIDE REDUCES TREATMENT COSTS IN LARGE VOLUME PAD STIMULATION

Background

An operator planning a large-scale hydraulic stimulation of a 7-well pad in the Montney formation was looking to determine the optimal solution for microbial control in their treatment fluid. They wanted to mitigate microbiologically influenced corrosion (MIC) and well souring, commonly caused by sulfate-reducing and acid-producing bacteria (SRB and APB).

Frequently Asked Questions

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.

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.

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.
