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.
