GENERAL DESCRIPTION
RiDrill™ WS2 is the next-generation of mechanically enhanced viscous wellbore strengthening LCM pills from Riteks. Formulated for extreme well conditions, RiDrill™ WS2 delivers unmatched stability at temperatures up to 400°F (205°C), making it the optimal choice for challenging HPHT environments. With reduced loading requirements and advanced rheological properties, RiDrill™ WS2 maximizes cost-efficiency while maintaining viscosity, suspension, and premium strengthening performance.

APPLICATIONS & BENEFITS
APPLICATIONS
APPLICATIONS & BENEFITS- Primary operations with clear fluids, WBM, or OBM
- Combine with Riteks LCM’s (RadiLock 3mm, Legion-LCM, Saber-LCM, or Arsenal-LCM) to treat severe losses
- Has substantial benefits for strengthening weak or depleted zones
FEATURES & ADVANTAGES
APPLICATIONS & BENEFITS- Forms a seal to minimize filtrate invasion and effectively reduces/eliminates losses
- Higher PV/YP at lower loadings than 1 st gen. strengtheners
- Provides wellbore strengthening & reduces incidents of induced losses downhole
- Capable of suspending multiple LCM's
- Sweeps and effectively removes cuttings
- Compatible with virtually all drilling fluids, surfactants, weighting agents, & LCM's
Recommendations
APPLICATIONS & BENEFITS- Recommended to use in systems up to 400°F (205°C)
- Depending on desired rheology, loadings can be varied from 7 to 20 lb/bbl
- For seepage to severe and even total losses, couple with Riteks LCM Products (RadiLock Fibers, Legion-LCM, etc...) for healing and sealing capabilities
