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 is different and requires a tailored program to meet the needs of the specific system.

NEW! AQUCAR™ 7140 LT and AQUCAR™ TN 250 LT Water Treatment Microbiocide and AQUCAR™ TN 250 LT Water Treatment Microbiocide

Winterized Biocides for Cold-Weather Hydraulic Fracturing Operations

From well-established basins like the Permian to colder regions like Western Canada and the Bakken, hydraulic fracturing activity continues to rise across North America. Shale basins are dependent, in part, on their surrounding environment, so as demand for oil increases in the Canadian, Bakken and Marcellus Basins, so has the need for winterized biocide products.

Dow Microbial Control’s new AQUCAR™ 7140 LT Water Treatment Microbiocide and AQUCAR™ TN 250 LT Water Treatment Microbiocide resists freezing at temperatures as low as -40°C and is now registered by EPA for use in the United States.
