OSPMICROCHECK.COM | INFO@OSPMICROCHECK.COM CASE STUDY 2K7 BIOCIDE REDUCES TREATMENT COSTS IN LARGE VOLUME PAD STIMULATION Competing biocide program replaced with combination of chlorine dioxide and 2K7 biocide background 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). challenge The 7-well stimulation design included the use of 350,000 m 3 of source water with a very high level of microbial contamination – 100x previous fresh water sources. The operator’ s current microbial contr
