Extender and Selective Flocculant
is a anionic copolymer designed to improve the
yield of bentonite while selectively flocculating
low yield solids.

health hazards are expected as a result of exposure to
DX-Extend. When handling any chemical, good personal hygiene

Selectively flocculates low yield solids.
Can be added to bentonite during milling operations or applied on-site.
For use in weighted and unweighted muds.
Can be used for interim viscosity increases.
2 pounds of DX-Extend should be added for every 5-8 sacks of bentonite.
The optimum amount of DX-Extend should be determined by pilot testing
with the bentonite that is on-site. Calcium levels should be treated
to below 200 ppm and preferably less than 100 ppm. The pH can be increased
to 9.5 to 10.5 with caustic soda (after the calcium has been reduced).
Since DX-Extend coats solids in the system, continued addition is
required as solids are removed. DX-Extend can also be used to generate
quick increases in viscosity for logging activities at the addition
rate of 2-3 lbs/100 barrels. The extending capabilities of DX-Extend
decrease with higher chloride levels. Use of DX- Extend by direct
addition should be discontinued at chloride levels greater than 10,000
ppm. However, use of DX-Extend can continue in the prehydration tanks
for the bentonite.
