APPLICATIONS & BENEFITS

APPLICATIONS

APPLICATIONS & BENEFITS
RiSweep-H is ideal for routine and complex cementing and drilling operations that require a reliable viscous fluid to ensure effective fluid displacement, reduced contamination, and improved zonal isolation. Its adaptable formulation makes it suitable for use in a variety of fluid environments and well designs, including both water based and oil based applications.

FEATURES & ADVANTAGES

APPLICATIONS & BENEFITS
  • Compatible with both fresh water and brine systems
  • Customizable rheology for optimal flow properties (adjustable YP)
  • Variable density for diverse well designs
  • Promotes excellent mud and spacer separation
  • Enhances wellbore cleaning and cement bond quality
  • Reliable, cost-effective option for everyday viscous spacers and drilling fluids
  • No known incompatibilities with any surfactants, weighting agents, or LCM's

Recommendations

APPLICATIONS & BENEFITS
  • Use in primary cementing or in drilling fluids where viscosity is needed
  • Depending on desired rheology, loadings can be varied from 7 to 20 lb/bbl
  • Designed for fluid systems below 250°F. If more temperature stability isneeded, please consider a Riteks RiSeal™ Spacer
