2K7 Bugstick / Slimstick Features and Benefits

  • Broad spectrum, non-selective antimicrobial chemistry
  • Non-ionic, highly compatible with other industrial chemicals
  • Balanced efficacy (good balance between speed and length of protection)
  • Simple application – just toss it in
  • Steady dissolution rate – dissolves in water over time
  • Sinks in water targeting microbes where they thrive – drops through hydrocarbons

2K7 Bugstick / Slimstick Recommended Uses

  • Batch applications (including addition into Frac, Saddle, Hydration, Buffer, and Settling tanks).
  • Use in low water volume and limited (restricted) access applications
    • Pre Treat Tanks
    • Fluid Transfer Control (Trucking, Pipeline, Lay Flat Hosing)
    • Asset Layup or Cleaning
  • The 2K7 Bugstick and 2K7 SlimStick are registered biocides, please refer to product label for approved directions for use.



Keep product in original outer bag until time of use.

OSP 2K7 Water Soluble Paks reduce bacterial load in coiled tubing fluid in the Eagle Ford


Coiled tubing (CT) is used for a variety of operations in oil and gas wells, including mill out of bridge plugs after cemented liner plug-and-perf stimulation. With each trip in or out of the wellbore, the CT string incurs a certain amount of fatigue that can be estimated using simulation software based on the CT outside diameter (OD) and material grade. CT units are retired at 80% of predicted fatigue. CT manufacturers have increasing empirical evidence showing that CT units experience premature string failures (below 80% fatigue) in certain areas, such as the Eagle Ford, Haynesville formations and Permian basin in Texas, and the Horn River and Montney formations in northern British Columbia. These string failures manifest in the form of pinholes and parting of the pipe. If these failures occur above ground, safety risks are a major concern. If they occur downhole, as detected by a sudden drop in tubing weight, the project is delayed and the costs of fishing out the broken pipe is incurred as well as the loss of the CT unit for future operations.

Frequently Asked Questions

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.

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.
