STAR-DRILL 2000
STAR-DRILL 2000 is a 50 % active synthetic polymer developed for use in freshwater and saltwater base drilling fluids. STAR-DRILL 2000 is a unique dispersion grade liquid PHPA that resists freeze/thaw degradation and phase separation.
Application
STAR-DRILL 2000 viscosifies rapidly and exhibits excellent hole-cleaning characteristics under low shear rates. It provides easy solids deposition in settling pits when used in core drilling. STAR-DRILL 2000 used alone or with KCL or substitutes will stabilize active shales by encapsulating the drilled cuttings and inhibiting formation swelling. STAR- DRILL 2000 creates thicker, stronger drill foams improving the cuttings-carrying capacity of the fluid and resisting water inflows.
Advantages
- Concentrated polymer content with longer shelf life than other liquid polymers
- Stabilizes clay, shale and mudstone formations
- Compatible with most drilling fluid additives
- Excellent all-round lubricant
- Can be used with foam to help stabilize loose formations and improve cuttings carrying
- Can act as a flocculant
