STAR-DRILL DRY
STAR-DRILL DRY is a high molecular-weight polymer designed for cuttings encapsulation and shale stabilization developed for use in low solids to weighted muds in fresh and salt make-up water. STAR-DRILL DRY acts as a viscosifier, friction reducer, and flocculant.
Application
STAR-DRILL DRY may be used in clear-water, solids-free drilling fluids. STAR- DRILL DRY enhances solids removal by flocculating low-gravity solids and increasing viscosity while providing cuttings encapsulation and improved wellbore stability. In reduced-bentonite systems, STAR-DRILL DRY extends bentonite to increase viscosity, flocculates drill solids for more efficient removal and encapsulates cuttings while improving wellbore stability. STAR-DRILL DRY can be used in weighted fluids for cuttings encapsulation, improved wellbore stability, viscosity and improved filter cake integrity. STAR-DRILL DRY sweeps are effective for periodic hole cleaning to help clear accumulated cuttings and maintain a clean hole
Advantages
- Excellent cuttings encapsulation that limits cuttings dispersion
- Improved shale stabilization
- Coats and lubricates solids to aid in preventing balling on the bit, stabilizers and BHA
- Enhances the removal of drill solids
Typical Usages
| Typical Amounts of STAR-DRILL DRY Added to freshwater | |||
|---|---|---|---|
| Drilling Application | lb/100 gal | lb/bbl | kg/m3 |
| Polymer mud systems | 0.6 - 2.4 | 0.25 - 1 | 1 - 3 |
| Mix STAR-DRILL DRY slowly into the active mud system to prevent "fish eyes" or premix at higher concentrations in a separate pit or chemical barrel, then blend into the active mud system | |||
| For sweeps, mix STAR-DRILL DRY directly in the active system at the suction pit or premix a high concentration in a separate pit and wait for the polymer to fully yield before pumping | |||
