A Better Water Treatment Solution for the Oil and Gas Industry

Chlorine dioxide improves oil recovery, increases well production, and boosts frac on the fly

Chlorine Dioxide’s (ClO2) versatility makes it the most effective and economical choice for oil and gas water treatment. Since the 1990s, International Dioxcide’s work in the oil and gas industry has proven that ClO2 offers greater microbial control (99.9%) and less corrosivity than alternative water treatments using chlorine, peroxide, bleach or ozone. Furthermore, chlorine dioxide produces significant savings by reducing treatment, logistical, and freshwater sourcing costs.

Improve Oil Recovery

Our decades of experience and independent testing have shown that chlorine dioxide water treatment can increase skim oil recovery up to 30 percent. Why? Because chlorine dioxide eliminates 99.9% of bacteria and the resulting iron sulfide and hydrogen sulfide (H2S) that cause significant emulsion. With chlorine dioxide, less emulsion means increased oil recovery and revenue. Chlorine dioxide destroys H2S by killing the sulfate reducing bacteria that produces it and oxidizing it to a sulfate.

Increase Production Rate

Another major benefit of chlorine dioxide water treatment is increased well production. In fact, chlorine dioxide can increase well injectivity by more than 150%. Chlorine dioxide achieves this by eliminating the oxidizable compounds and biofilm that “plug” saltwater disposal or injection well operations. ClO2 eliminates 99.9% of bacteria and the resulting iron sulfide and hydrogen sulfide (H2S) that cause significant emulsion and fouling.

Other benefits:

  • Restores frac wells to their original production rates
  • Removes iron sulfide contaminated wellbore damage

Save on Frac Water Treatment

In addition to improved well production and oil recovery, chlorine dioxide can reduce frac water treatment costs by 20% or more. Chlorine dioxide eliminates 99.9% of acid-producing and sulfate-reducing bacteria and reduces bottle turns to zero━and it achieves this at a lower dose compared to other biocides.

Other benefits:

  • Reduces truck traffic by 50% or more
  • Reduces frac well freshwater sourcing costs by up to 90%
