History

The sixty frac ponds involved in this case study:

• Had baseline SRB counts of 100,000 cells/mL or greater
• Operator typically used 750 ppm biocide per frac water
• Cost per frac biocide was $65,000 per 100,000 Bbl lined frac pit or pond

Treatment Goals

• Signifianctly reduce SRB population during pre-treatment prior to frac
• Reduce biocide ppm and expense
• Reduce future risk of H2S
• Reduce future risk of iron sulfide scale

Results

• Expenses per frac reduced by 50%, resulting in $26,700 savings, including the cost of the the microbes
• SRB reduced to 1,000 cells/mL or less per frac water
• Of 60+ frac water treatments, only 2 wells have shown any ppm of H2S gas, and only 1 was higher than 10 ppm
• As a result of this project, this operator is using Bio Tech's pre-treatment program to treat virtually all their frac water
