SAND-STAR
SAND-STAR is a specialty blend of synthetic polymers specifically designed for drilling through unconsolidated sand and silt. It also provides cuttings encapsulation and shale stabilization. SAND-STAR acts as a viscosifier, friction reducer and fluid loss control additive in fresh and saltwater.
Application
SAND-STAR is used when drilling in unconsolidated sand and silt. SAND-STAR consolidates loose formations allowing for efficient installation of casing. SAND-STAR increases core recovery by reducing the opportunity for caving sand and silt and wash out.
Advantages
- Unique polymer blend designed to quickly hydrate and consolidate troublesome geology
- Effective when encountering clay seams by encapsulating drilled cuttings and reducing swelling/sticking of formation clays
- Enhances the removal of drill solids
- Maintains hole stability while drilling to install surface casing
