VIS-STAR FP
VIS-STAR FP is a readily dispersible, ultra-high molecular weight anionic polymer designed to provide cuttings encapsulation, fluid loss control and clay/shale stabilization. VIS-STAR FP acts as a viscosifier, reduces friction and flocculates fines in the fluid. It can be added to the system or directly to the borehole. VIS-STAR FP can be used in drilling and in trenching.
Application
VIS-STAR FP will increase the viscosity and enhance the overall ability of drilling fluids. Improving fluid loss, clay/shale stabilization, and cuttings encapsulation and removal. VIS-STAR FP ,in low doses, can be used to extend bentonite based fluids, further increasing the base fluid properties. VIS-STAR FP will bind together unconsolidated formations increasing well-bore stability. It will also flocculate fines, allowing them to settle and help maintain a clean fluid.
Advantages
- Can be mixed in the borehole or into the excavation
- Clay and shale stabilizer (encapsulator)
- Enhances the removal of drill solids, clean fluid
- Non-gelling, allowing for the settlement of fine
- Reduces skin friction (Lubrication)
- Improves fluid loss and bore stability
