Based in Houston, Texas, Nissan Chemical America Corporation is a division of Nissan Chemical Corporation founded in Japan in 1887. A forerunner in chemical innovations for more than 130 years, Nissan Chemical has been perfecting nanoparticle technology since 1951, making it one of the first companies in the world to produce highly surface-modified colloidal particles for industrial applications.
nanoActiv® EFT increases profits through greater initial oil and gas production. It is a nanoparticle micellar dispersion, which uses a synergistic combination of silicon dioxide nanoparticles, a soybean extract solvent, and a blend of surfactants. nanoActiv® EFT exhibits an extremely effective primary chemical action, enhanced with the added mechanical properties of nanotechnology. nanoActiv® EFT reduces interfacial tension and exhibits wettability modification, combined with the unique effects of diffusion, disjoining pressure, fragmentation, and reduction in interfacial tension. It improves stimulation fluid interaction near the created and propped fracture faces, and throughout the entire propped fracture network — increasing initial oil and gas production.
Hydraulic fracturing can introduce a variety of fracturing fluid systems into unconventional reservoirs. When a lower salinity fracturing fluid comes into contact with a higher salinity low permeability formation, fracturing fluid filtrate can get trapped into the pore spaces due to a difference in osmotic potential. This can lead to an increase in the water saturation and a problematic decrease in hydrocarbon mobility in pore spaces.
nanoActiv® EFT reaches surfaces adjacent to both primary and secondary fractures to improve cleanup and flow efficiency.
nanoActiv® EFT reaches into small pore spaces — releasing more immobilized oil than ever before — delivering significantly more efficient and complete flowback of the treatment fluids over a shorter period of time.

nanoActiv® EFT effectively displaces hydrocarbons by reducing the interfacial tension of the fracturing fluid and mobilizing immobile water-block zones in pore spaces. The presence of nanoparticles in nanoActiv® EFT significantly increases the efficiency of the technology by contacting more surface area with a Brownian-motion, diffusion-driven mechanism known as disjoining pressure. The nanoparticles in nanoActiv® EFT fragment hydrocarbons into smaller droplets, allowing efficient recovery of fluids pumped and onset of rapid production. It cleans up residual fracturing fluid components such as residual gel and maintains maximum flow capacity of the proppant pack.
nanoActiv® EFT is designed to be pumped in the body of the fracturing fluid as an additive at concentrations between 1 gallon and 5 gallons per 1,000 gallons of fracturing fluid. This allows nanoActiv® EFT to aid in a more efficient and complete flowback of the fracturing fluid — radically increasing the percentage flowback over a shorter time period.
