STAR-TECH 151
STAR-TECH 151 polymer blend is designed to provide cuttings encapsulation, fluid loss and shale stabilization. STAR-TECH 151 acts as a viscosifier and friction reducer and works well for setting surface casing.
Application
STAR-TECH 151 systems provide excellent cuttings encapsulation and improved wellbore stability. Thicker mixtures should be used when groundwater and highly fractured formations are encountered. Thicker solutions of STAR-TECH 151 may be required to coat the borehole and casing when setting casing. STAR-TECH 151 may be mixed as required for air drilling
Advantages
- Provides excellent cuttings encapsulation and limits cuttings dispersion
- Provides improved shale stabilization and has excellent shear resistant properties
- Enhances the removal of drill solids
- Mixes and yields easily
- Aids in preventing balling on the bit, stabilizers and bottom-hole assemblies by coating and lubricating solids
- Functions to stabilize unconsolidated ground and prepares the upper hole to receive casing - as a result, casing removal is greatly improved.
Typical Usages
