Nissan Chemical America receives its first oilfield nanotechnology patent

August 22, 2019

PASADENA, TX - Nissan Chemical America Corporation has received its first US patent, “Hydrocarbon Formation Treatment Micellar Solutions," for its nanoActiv enhanced flowback dispersion additive.

nanoActiv EFT is the first micellar dispersion additive that applies nanoparticle technology to increase initial oil and gas production. nanoActiv EFT is a synergistic combination of Nissan’s proprietary silicon dioxide nanoparticles, an organic solvent, and a blend of surfactants. These technologies work together to efficiently overcome problems presented by increases in water saturation and decreases in hydrocarbon mobility.

“For the nanotechnology to do its job, the particles must be uniform in size and remain separate from each other. In the presence of brine, that is a very difficult thing to do,” says NCA technology director John Southwell. “We solved this challenge by engineering highly surface-modified brine-resistant nanoActiv particles with the ability to remain a colloidal dispersion in challenging downhole conditions.”

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.

The benefits of nanoActiv EFT are amplified when used in combination with nanoActiv HRT to syngergistically increase initial oil and gas production while reaching deeper into the fracture network creating pathways for sustained recovery.

“Nissan Chemical’s nanoActiv products are the only true nanoparticle solutions in the industry. This patent is a big step forward as the nanoActiv brand continues to grow,” adds NCA president William Smith. “Our innovative products for the oil & gas industry consistently give operators improved returns.”
