DYNALOSE™ Y

PRODUCT BULLETIN

FILTRATION CONTROL AGENT

This document is supplied solely for informational purposes and Newpark Drilling Fluids makes no guarantees or warranties, either expressed or

implied, with respect to the accuracy and use of this data.

All product warranties and guarantees shall be governed by the General Terms and Conditions.

PRODUCT DESCRIPTION

DynaLose™ Y filtration control agent is a pre-gelatinized,

 yellow-colored cornstarch used in water-based drill ing fluids.

It is effective in all water-based fluids, including seawater,

salt-saturated, and high-hardness (calcium) drilling

fluid systems.

BENEFITS

DynaLose Y starch reduces filtration by swelling and

then blocking small openings in the filter cake. It will

not significantly increase the rheological properties of

the drilling fluid system in which it is used.

APPLICATION

DynaLose Y filtration control agent should be applied in an

alkaline environment where it delivers its best performance.

TREATMENT RECOMMENDATION

DynaLose Y filtration control agent is used in concentrations

of 2-6 lb/bbl, depending on the amount of drilled solids

present in the drilling fluid system. Oxygen scavengers

should be used to reduce thermal degradation. In the

absence of high pH or high salinity, a bactericide should

be used. DynaLose Y powder mixes readily into the

system through the hopper at rates of 5-10 minutes per

sack to prevent balling and fish eyes. Starch is subject to

bacterial degradation. When used in freshwater drilling

fluids with a pH lower than 11. 5, a bactericide is required.

DynaLose Y filtration control agent is stable at bottom

hole temperatures up to 200°F (93°C).
