Nu-Well 220 Dispersant Polymer

In new well systems, use Nu-Well 220 dispersant polymer as you would phosphates for drilling mud breakdown and well development. For optimal removal of bentonite drilling fluids, separately pre-treat the well with 1,500 ppm chlorine to break down the polyacrylamide polymers that are included in most commercial bentonite products. Determine borehole volume, and apply Nu-Well 220 dispersant polymer at the rate of 1 gal. per 500 gal. of water. Vigorously agitate by mechanical means for several hours (approximately 1/2 hour per 20 ft. of intake). If left in the well overnight, agitate before pumping out.

Insights

In older well systems use, Nu-Well 220 dispersant polymer to remove fine sands, mud and clays that have filled in the gravel pack and borehole. Use at a rate of 1 gal. per 300 gal. of water. Vigorously agitate (by mechanical means), allowing the solution to stand in the well overnight and repeat the agitation the next day, before pumping out.

Description
  • Nu-Well 220 dispersant polymer uses liquid dispersant chemistry specifically designed to remove mud and clay from the well environment
  • Successfully develops new wells without using phosphate
  • Eliminates food source for bacteria (100 percent water soluble, readily flushed from well)
  • Rehabilitates old wells plugged with clays, silts and fines
  • NSF approved for potable water well use

Example 

Old 12 in. well, total depth = 600 ft., SWL =  50 ft.

- Find dosage factor (old or new well)

- Multiply static height by dosage factor

- Mix and apply to well or circulating system

Step 1: Dosage factor = 0.024 gal./ft.

Step 2: 550 ft. x 0.024 gal./ft. = 13.2 gal.

Step 3: 13 gal. of Nu-Well 220 dispersant polymer needed
