Aqua-Star D is a derivitized starch-based fluid loss control agent capable of enhancing
rheology and providing lubricity when used in conjunction with various shear-thinning
polymers. It is a sodium carboxymethyl starch.

Aqua-Star D exhibits fluid loss control efficiencies similar to the cellulosics. The synergistic
behaviour of Aqua-Star D with bentonite and other polymers enhances the shear thinning
properties of a drilling fluid and thus provides excellent hole cleaning at low shear rates.
Aqua-Star D’s ability to coat clay and shale particles aids in controlling dispersion and the
eventual destabilisation of well bores. Aqua-Star D’s ability to encapsulate drilled solids
facilitates their removal at surface.
With the addition of an oxygen scavenger Aqua-Star D can be temperature stable up to 150ºC.
Aqua-Star D is non-fermenting and requires no biocide under normal conditions. Aqua-Star D
exhibits greater stability to enzyme contamination than typical stabilized fluid loss polymers.
Aqua-Star D is used in concentrations ranging from 5.0-25.0 kg/m3 depending on fluid loss
requirements and the amount of solids in the system.
MIXING AND HANDLING
Aqua-Star D mixes readily and may be added to a mud system through the hopper at 10-15
minutes per sack. It is advisable to use a dust mask and eye protection while mixing all
