Hydraulic Fracturing

Optimize microbial control treatment for water in hydraulic fracturing operations

Hydraulic Fracturing Operations

An optimized microbial control treatment program requires a strategy to address each of the three phases of hydraulic fracturing: preparing the water, decontaminating the well, and protecting the reservoir.

As a leader in optimized microbial control for hydraulic fracturing operations, Dow recommends biocides based on the conditions of each phase, considering temperature, salinity, aerobic and anaerobic conditions, and the desired duration of control. Each application (shale play or well) is different and requires a tailored program to meet the needs of the specific system.
