CyberVis RM polymer is specifically engineered and field proven to provide increased low-end rheology and yield point.


The primary application for CyberVis RM rheology modifier is in the preparation of new drilling fluids at the liquid mud plant where shear rates and mixing times are insufficient to fully stabilize the emulsion. The additive’s effectiveness will diminish as bottomhole temperatures increase from 350°F (177°C) to 425°F (218°C).

Treatment Recommendation

Treatment levels are best determined by pilot testing, but generally will be less than 4 lb/bbl (0.55 gal/bbl). Over-treatment should be avoided in freshly mixed drilling fluids as the organophilic clays will fully yield and the emulsion will tighten after a circulation through the bit.
