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).
