DPAM Series Friction reducers of anionic and cationic hydration quick Solid (powder) for saline brines. DPAM Series is a fast-hydrating, high-performance dry friction reducer (DFR) for stimulation fluids in both fresh water and brines with low to medium salinity. With a low dosage (1 to 2 pptg), it reduces friction pressure in excess of 70%. As a solid powder product, DPAM Series has significant logistic and storage benefits. It’s also advantageous in economic and environmental considerations versus conventional emulsion-based friction reducers, since it has no organic solvents or harsh surfactant chemicals, unlike in emulsion-type (EPAM) products. It hydrates rapidly in fresh water and in typical light brine solutions to achieve maximum performance in less than a minute. This is particularly useful for well stimulation where additions by “on-the-fly” operations are demanded. This dry friction reducer can be fully activated when mixed with fresh water or moderate salinity brines.

EPAM Series is an ultra-high salinity tolerant liquid-based friction reducer that is specifically designed as an additive to very heavy brines or return fracturing fluids. Additions of small amounts of EPAM Series (typically, 0.25 - 1 gpt) in hydraulic fracturing fluid can reduce the friction pressure by up to 70% in less than one minute. EPAM Series is a high molecular weight, partially hydrolyzed anionic PAM- copolymer. Alkyl phenol ethoxylates (APE) and nonylphenol ethoxylates (NPE) are excluded from the ingredients, which makes EPAM Series more environmentally benign than other emulsion products. As an emulsion-type product, EPAM Series inverts rapidly even in high TDS or poor quality water. Applications are versatile through continuous additions to stimulation fluids by “on-the-fly” method or batch mixing before treatments.
