Tech Talk: How Much Freshwater Do You Need?
Optimize hydraulic fracturing stimulation while minimizing costs and environmental impact.

Hydraulic fracturing stimulation operations have gradually increased to maximize reservoir drainage in tight conventional and unconventional fields. This, however, has put a strain on freshwater requirements while increasing costs for flowback water handling and disposal. When high-viscosity friction reducers were introduced, they reduced hydraulic horsepower requirements and simplified traditional slickwater hybrid designs. Similar proppant carrying capacity to more viscous linear or crosslinked gel fluids reduced overall volume of fluid required.

Research along this path of water and power conservation has led to the development of dry and higher-salinity, produced-water-compatible high-viscosity friction reducers. Dry high-viscosity friction reducers simplify transportation and logistics and improve the overall environmental footprint by eliminating petroleum distillates and risk of spillage on location.

Our innovative high-salinity high-viscosity friction reducer extends the capacity of this viscous slickwater fluid portfolio. It enables reusing produced water and other nonfresh water sources with salinity ranges up to 300,000-mg/L total dissolved solids. Overall, our engineered viscous slickwater portfolio provides simplicity, cost and operational efficiency, water reuse capacity, and a low environmental footprint to optimize the success of your fracturing operations.
