GENERAL DESCRIPTION
Riteks Legion-LCM - Multi-Modal LCM is a highly-efficient, multi-modal loss circulation material engineered to combat downhole losses
across a broad range of applications. Riteks Legion-LCM - Multi-Modal LCM is an effective bridging and sealing agent when used in
conventional spacers and cement slurries, but added performance is witnessed when coupled with one of Riteks
RiSeal™ Sealing Spacers. This specially formulated all-in-one single sack solution minimizes operational
complexity, saves time, and provides superior down hole performance.

APPLICATIONS & BENEFITS
APPLICATIONS
APPLICATIONS & BENEFITSRiteks Legion-LCM - Multi-Modal LCM is designed for use in both preventative and remedial loss circulation
applications during drilling and cementing operations. Riteks Legion-LCM - Multi-Modal LCM is Riteks' most
effective plugger to date. It can plug a 3 mm slot with just 10 to 15 lb/bbl loading
depending on carrying fluid. Recommended loadings are 0.5 to 3 lb/bbl for loss
prevention to seepage type losses, 4 to 7 lb/bbl for partial losses, and 8 to 15
lb/bbl for severe or total losses. To ensure safe passage through wellbore
restrictions, Riteks Legion-LCM - Multi-Modal LCM concentrations should be adjusted accordingly. The
carrying fluid must maintain a rheological profile that supports dynamic and static
suspension, considering interactions with surrounding fluids and thermal changes
to prevent settling and flow disruptions.
FEATURES & ADVANTAGES
APPLICATIONS & BENEFITS- Wide array of particle sizes capable of sealing slotted openings up to 3000 microns
- Excellent low pressure and high pressure LCM
- Capable of bridging and sealing
- Pre-blended, single-bag format reduces bulk plant preparation time
- Very compatible with water-based and oil-based fluid systems
- Helps to ensure proper top of cement
- Helps to prevent leak-off, fallback, and improves barrier integrity
- When coupled with Riteks RiSeal™ Spacers, can eliminate the need for a DV Tool and cure severe losses
