THIXATROL^® DW 50

THIXATROL DW 50 is a unique proprietary organic polymer that generates an efficient rheological profile in synthetic based invert emulsion drilling fluids while having a minimal viscosity increase when subjected to reduced temperatures. This highly desirable flat rheological property is stable through 350ºF and can be extended to applications beyond deep water drilling.

In addition to maintaining a consistent or flat rheological profile from 40ºF through 350ºF, THIXATROL DW 50 is not toxic to marine life.

THIXATROL DW 50 exhibits an excellent balance of dispersibility for initial viscosity build, efficiency for cost effectiveness and tolerance to adverse conditions for reduced depletion rates. Control of ECD is significantly improved as compared to drilling fluids incorporating only conventional rheological additives. 

Key properties

• “Flat” rheological profile from 40ºF through 350ºF for reduced low temperature viscosity build and improved ECD control for the elimination or reduction of mud losses. 35% reduction in 40ºF HSRR.
• Stable to bottom hole temperatures in excess of 350ºF
• PARCOM (Class D) / Mysid & Lepto compliant for global offshore applications
• Maintains HTHP fluid loss control
• Shear thinning rheological profile for improved ROP
• Compatible with conventional invert emulsion drilling fluid additives and contaminants
• Builds viscosity in clay free systems or with organoclays
• Efficient hole cleaning and suspension properties for sag control
