In order to provide our customers across the globe, operating assets in unconventional markets, with new and consistent levels of operational efficiency, treatment cost reduction, and higher production returns from better fractured wells, ZL offers unique polymer chemistry for use in slick-water hydraulic fracturing applications. Such chemistry was designed with the dual functionality of being able to deliver superior friction reduction at ultra low dosages without compromising the ability to place high proppant loadings far into the formation during high-rate slick-water applications. 

ZL's R&D team, headquartered in Zhengzhou, China, has been working since 1995 to extensively understand and optimize polymer chemistry for polymer flooding, and in more recent years slick-water hydraulic fracturing. The R&D capabilities and equipment used to evaluate polymer chemistry performance at ZL is unlike anywhere else in the world.


Chemistry Class

Our capabilities to optimize hydration and dissolution time, viscosity build-up and retention, the impact of mechanical shear degradation, and friction reduction can be conducted using our 4.5 inch diameter flow-loop, which extends over 3,500 feet and is connected to a ZL compact polymer dispersion unit, equipped with four different sampling points. It is through our extensive research on polymer chemistry through the years that we have been able to provide differentiating polymer chemistry for use in unconventional fracturing.

ZL's family of liquid friction reducers, UltraFlo, are anionic polymers slurried in a clay-free suspension package. ZL's suspension package was carefully designed to eliminate potential polymer separation extending the shelf life to months, which is unlike emulsion based friction reducers. 




The same polymer chemistries slurried in ZL's liquid friction reducers are available in larger mesh sized dry powder. Our dry polymers can be instantaneously hydrated while pumping the dry polymer on the fly at the well-site using ZL's compact dispersion unit. Hydrating larger mesh sizes of dry polymer, without having to the slice the polymer to hydrate, results in a higher molecular weight friction reducer with higher viscosity and better proppant suspension and transport capabilities, and lower shear degradation susceptibilities.
