Bacterial contamination from drilling and fracturing can lead to serious problems in unconventional oil and gas shale plays. Large water volumes for these processes are transported from aquifers municipal waters rivers lakes ponds or oilfield flowback water to the wellsite and stored in frac tanks or earthen impoundments. Typically these waters are contaminated with bacteria. Furthermore fracturing fluids contain gelling agents or polyacrylamide-based friction reducers which are readily available bacterial food sources. If these fluids are insufficiently treated establishment of sulfate-reduction bacteria (SRB) and acid-producing bacteria (APB) can lead to operational issues including: 1) biogenic sulfide production and formation souring 2) plugging from iron sulfide scale production 3) microbially influenced corrosion (MIC) and 4) premature degradation of fracturing fluids. As operators continue to search for solutions to control bacteria induced issues in unconventional shale plays an ideal biocide with the following characteristics would be required: (1) environmentally safe (2) broad spectrum (against SRB and APB) with fast kill times at low concentration (3) neutralization of hydrogen sulfide and other corrosion causing chemicals (4) removal of iron and other scale forming ingredients (5) compatible with drilling fluids (6) cost effective and readily available (7) scalable for future production model (multi-pad) (8) economy of scale: could be generated onsite with mobile unit
