NuWell 400 Non-Ionic Surfactant


NuWell 400 Non-Ionic Surfactant

Nu-Well 400 non-ionic surfactant is a non-ionic surfactant capable of use over
a wide pH range. The non-ionic nature ensures that the surfactant neither
reacts directly nor interferes with any other chemical being used. The surfaceactive properties of Nu-Well 400 non-ionic surfactant are excellent for improving
penetration of hard deposits or for wetting surfaces to be cleaned.
Nu-Well 400 non-ionic surfactant may also be used to improve flow characteristics
of heavy fluid or muds used in well construction. By changing the surface tension,
Nu-Well 400 non-ionic surfactant improves cleanup of oil or biologically fouled

Nu-Well 400 is surfactant designed to improve cleaning efforts in tight formations
or heavily impacted well systems.
Nu-Well 400 non-ionic surfactant is used at the rate of 1 gal. per 1,000 gal. of
water in the system to be cleaned or the total gallons of cleaning solution to be
used. If the system is being cleaned for oil or heavy biofouling, use Nu-Well 400
non-ionic surfactant at the rate of 1 gal. per 500 gal. of water.
