DriFlow™ A Fully Integrated Dry FR Delivery System

“For our last pad, we used both HiFlow 5 and DriFlow™ FR’s for comparison of abilities of the products as well as to determine cost difference. We had 218 stages over 3 wells. I can say that the DriFlow™ performed as well as the HiFlow 5 with a comparable product cost reduction of ± 18% for thecompleted job. We plan to swap all of our crewsto DriFlow™”

- COO, Permian Basin Operator

Why DriFlow™?• Reduces spend on FR by 15 – 20%

• Exceptional results in all water qualities

• Slick water and enhanced rheology applications

• True “dry-on-the-fly” operation

• Custom digital control platform with integration to data van

• Reduces logistics to location by 300%

• Greatly reduces HSE risks associated with liquid FR’s

DriFlow™

Polyacrylamide chemistries are a vital component to unlocking the hydrocarbons that are trapped in unconventional reservoirs all around the world. On average, friction reducers account for approximately 55% of the total chemical spend on a stimulation job. The conventional delivery method for polyacrylamides has been liquid emulsions or liquid slurries that contain only 20 – 40% active polymer content. This has proven to be highly inefficient from a logistics standpoint and contributes to higher costs.

In January 2019, DCS introduced its first DriFlow™ dry polymer unit to the market. Utilizing proprietary polymer dispersion technology and in-house system development, our DriFlow™ units have set the bar

for performance and cost reduction.
