Acid can impact the particles’ coating. Hence, it has to be spent before nanoActiv® is pumped. We generally pump water spacers before and after pumping nanoActiv® to make sure nanoActiv® does not come in contact with acid.
We have seen many instances with increased oil and gas production. Intuitively, this would also make sense, as lighter density fluids should be easier to recover. We have recently pumped in gas-only wells and are waiting for more data.
There are two versions of nanoActiv® HRT. The higher temperature version can withstand up to 180° C (350° F).
- Up to 100k mg/l: there is no issue at all.
- Between 100k and 200k mg/l: can work but needs lab testing to confirm specific cases.
- Above 200k mg/l: not likely to work, will still run compatibility testing to confirm.
Naturally fractured reservoir, oil-wet, tight, and low permeability along with fractures away from aquifers are the ideal scenarios. In all cases, candidate wells will be discussed and screened with involvement of both parties (operator and technology provider).
Nissan Chemical has been perfecting nanoparticles since 1951, making it one of the first companies in the world to produce highly surface-modified particles for industrial applications. Our years of experience, proprietary materials, and patented technologies have helped us become a worldwide leading provider of refined nanoparticle solutions.
