0% and 2% NaCl wellbore fluid

[johnchrc]

I am curious what a 0% NaCL fluid is. Is that just distilled water?

We make a polymer that absorbs freewater from typical wellbore water based and oil based muds. The more freewater (less salt), the faster the polymer swells and isolates producing zones downhole.

2-10% NaCL is common with the lower sodium content having the faster swell time.

Any comments on 0% NaCl?

If there was such a thing as 0% NaCL fluid, then yes, it would be a low salt water. However, if the water was a 0% NaCL fluid, there may be other minerals present.

0% NaCL fluid is more of a theoretical concept. See the attachment. It is not uncommon for fresh water to have a 0.01% NaCL concentration.
